Dylan plants grass in a rectangular space behind the clubhouse.the area of the space is 70 square feet. If the length of the space is 14 feet . what is the width of the space
Answer:
The width of the rectangular space = 5 ft.
Step-by-step explanation:
The area of the rectangular space = 70 sq ft.
The length of the rectangular space = 14 ft
The width of the rectangular space - m ft
Now, AREA OF THE RECTANGLE = LENGTH x WIDTH
⇒ 70 sq ft. = 14 ft x m ft
or, m = 70 / 14 = 5 ft
or, m = 5 ft
Hence the width of the rectangular space = 5 ft.
50 points! A polynomial has been factored below, but some constants are missing. 2x^3 - 8x^2 - 24x = ax (x+b)(x+c) What are the missing values of a, b, and c?
The missing values are [tex]\( a = 2 \), \( b = 0 \), and \( c = -24 \),[/tex] yielding the factored form [tex]\( 2x(x - 24) \).[/tex]
To find the missing values of[tex]\( a \), \( b \), and \( c \)[/tex], we need to expand the polynomial [tex]\( (x+b)(x+c) \)[/tex]and equate it to [tex]\( 2x^3 - 8x^2 - 24x \).[/tex]
Expanding [tex]\( (x+b)(x+c) \),[/tex] we get:
[tex]\[ (x+b)(x+c) = x^2 + (b+c)x + bc \][/tex]
Comparing this to [tex]\( 2x^3 - 8x^2 - 24x \),[/tex]we see that:
[tex]\[ x^2 + (b+c)x + bc = 2x^3 - 8x^2 - 24x \][/tex]
We need to match the coefficients of corresponding terms on both sides of the equation.
From the equation above, we can equate coefficients:
1. Coefficient of [tex]\( x^3 \): \( 2 = 0 \)[/tex] (there is no [tex]\( x^3 \)[/tex] term on the right side).
2. Coefficient of [tex]\( x^2 \): \( 1 = -8 \) (from \( x^2 \) term)[/tex].
3. Coefficient of [tex]\( x \): \( b + c = -24 \) (from \( x \) term).[/tex]
4. Constant term: [tex]\( bc = 0 \)[/tex] (there is no constant term on the right side).
From the last equation, we know that either [tex]\( b \) or \( c \)[/tex]must be zero, or both.
If one of them is zero, then the other must be equal to [tex]\( -24 \)[/tex] for the equation [tex]\( b + c = -24 \)[/tex] to hold true.
Now, we can test some values to satisfy these equations:
1. If [tex]\( b = 0 \)[/tex]
[tex]\[ c = -24 \][/tex]
2. If [tex]\( c = 0 \):[/tex]
[tex]\[ b = -24 \][/tex]
3. If both [tex]\( b \) and \( c \)[/tex]are non-zero:
We can solve the equation [tex]\( b + c = -24 \)[/tex] for various values of [tex]\( b \) and \( c \).[/tex]
Therefore, possible combinations are:
1.[tex]\( a = 2 \), \( b = 0 \), \( c = -24 \)[/tex]
2.[tex]\( a = 2 \), \( b = -24 \), \( c = 0 \)[/tex]
3.[tex]\( a = 2 \), \( b = -12 \), \( c = -12 \)[/tex]
So, the possible missing values are:
1. [tex]\( a = 2 \), \( b = 0 \), \( c = -24 \)[/tex]
2. [tex]\( a = 2 \), \( b = -24 \), \( c = 0 \)[/tex]
3.[tex]\( a = 2 \), \( b = -12 \), \( c = -12 \)[/tex]
Solve the inequality $-4x > -24.$ Give your answer in interval notation.
Final answer:
To solve the inequality -4x > -24, divide both sides by -4 and flip the inequality sign to obtain x < 6. The solution in interval notation is (-∞, 6).
Explanation:
To solve the inequality -4x > -24, we can divide both sides of the inequality by -4. Remember, when dividing or multiplying both sides of an inequality by a negative number, the inequality sign flips. So, the inequality becomes:
x < 6
The solution in interval notation is (-∞, 6).
Final answer:
The solution is x < 6, which is represented as (-∞, 6) in interval notation.
Explanation:
To solve the inequality -4x > -24, we can start by dividing both sides by -4.
Divide both sides of the inequality by -4. Remember that when you multiply or divide both sides of an inequality by a negative number, the direction of the inequality sign changes.
However, when dividing an inequality by a negative number, the direction of the inequality sign must be flipped. So we have x < 6.
Since the inequality sign is less than, the solution set is all values of x that are less than 6. In interval notation, this is represented as (-∞, 6).

on dividing $200 between A and B such that twice of A's share is less than 3 times than B's share by $20
Answer:
Share of A is $116 and Share of B is $84.
Step-by-step explanation:
Let the share of A be [tex]x[/tex]
Let the share of B be [tex]y[/tex]
Given:
$200 is shared between A and B
So, [tex]x+y =\$200\ \ \ \ equation \ 1[/tex]
Also given;
twice of A's share is less than 3 times than B's share by $20
[tex]2x= 3y -20\\2x-3y = -20 \ \ \ \ equation \ 2[/tex]
Solution:
Now multiplying equation 1 by 3 we get,
[tex]3x+3y=600 \ \ \ \ equation \ 3[/tex]
Now Adding equation 2 and equation 3 we get
[tex](2x-3y = -20)+ (3x+3y=600)\\5x=580\\\\x=\frac{580}{5}=\$116[/tex]
Now Substituting the value of x in equation 1 we get,
[tex]x+y=200\\116+y=200\\y=200-116 = \$84[/tex]
Hence, Share of A is $116 and Share of B is $84.

Two times a number, plus five, equals the number, minus five.
Find the number and type it in the box.
Answer:
Answer:
x= -5
Step-by-step explanation:
let the number be x.
2x+5= -5 ====> equation
2x= -5-5. (shifted the +5 to the other side)
2x= -10
x= -10/2 ( shifted 2 on the other side as it was multiplying with x)
x= -5
Final answer:
To solve the equation 'two times a number, plus five, equals the number, minus five,' we set up and simplify the algebraic equation 2x + 5 = x - 5, which ultimately gives us the number x = -10.
Explanation:
The problem states that two times a number, plus five, equals the number, minus five. To find the number, we can set up the equation 2x + 5 = x - 5, where x represents the number we're trying to find.
Step 1: Start by subtracting x from both sides of the equation to get all the x terms on one side and the constant terms on the other side. The equation then becomes: 2x - x + 5 = x - x - 5, simplifying to x + 5 = -5.Step 2: Next, we subtract 5 from both sides of the equation to solve for x: x + 5 - 5 = -5 - 5, which simplifies to x = -10.Therefore, the number we were trying to find is -10.

the ratio of black bags to blue bags is 5 to 3 if there are a total of 10 black bags then how many blue bags are there
Answer:
6
Step-by-step explanation:
3 times 2
Is 6 and 5 times 2 is 10
Final answer:
To find the number of blue bags, we calculate based on the 5 to 3 ratio with 10 black bags. Each part corresponds to 2 bags, hence there are 6 blue bags.
Explanation:
The question concerns the calculation of the quantity of blue bags based on a given ratio to the quantity of black bags. If the ratio of black bags to blue bags is 5 to 3, and there are a total of 10 black bags, then we can set up a proportion to find the number of blue bags.
To solve this, we assume the number of black bags (5 parts) equals 10, which means each part corresponds to 10 / 5 = 2 bags. Since there are 3 parts of blue bags in the ratio, we then multiply the number of bags per part by 3 (the number of blue parts), which gives us 3 * 2 = 6 blue bags.
x^(logx) = 1000000x
Find x.
Answer:
[tex]x = 1000[/tex] or [tex]x = 0.01[/tex]
Step-by-step explanation:
We are given a logarithmic equation of x and we have to solve it for x.
Given,
[tex]x^{\log x} = 1000000x[/tex]
⇒ [tex]x^{\log x} = 10^{6} \times x[/tex]
Now, taking log on both sides, we get
[tex]\log x^{\log x} = \log 10^{6} \times x[/tex]
⇒ [tex]\log x .\log x = \log 10^{6} + \log x[/tex]
{Since [tex]\log a^{b} = b\log a[/tex] and [tex]\log ab = \log a + \log b[/tex]}
⇒ [tex](\log x)^{2} = 6 + \log x[/tex]
{Since log 10 = 1}
⇒ a² = 6 + a {Where, a = log x}
⇒ a² - a - 6 = 0
⇒ (a - 3)(a + 2) = 0
⇒ a = 3 or a = -2
⇒ [tex]\log x = 3[/tex] or [tex]\log x = - 2[/tex]
Now, converting logarithm to exponential form, we get,
⇒ [tex]x = 10^{3} = 1000[/tex] or [tex]x = 10^{- 2} = \frac{1}{100} = 0.01[/tex] (Answer)

Write a word problem using 7 groups. Solve your problem?
A real-world problem using 7 groups can be illustrated like a builder constructing 7 buildings each requiring 15 bricks per day. Multiplying these, 7 times 15 gives us 105, which is the total number of bricks needed each day.
Explanation:Consider a scenario where a builder is constructing 7 buildings. Each building needs 15 bricks per day for construction. We can therefore write a multiplication problem to find out how many total bricks are needed each day.
So, 7 (groups of buildings) multiplied by 15 (bricks per building) equals a total daily brick requirement. To solve this, you simply multiply 7 by 15 which equals 105 bricks needed each day.
This is a simple real-world problem to help understand the concept of multiplication as repeated addition. Here, you're adding 15 bricks 7 times since there are 7 buildings.
