To find out how many square tiles Mr. Grant needs, you need to know the total area he wants to cover. The area of each tile is 9 square feet. Divide the total area by 9 to find the number of tiles he needs.
Explanation:In order to figure out how many square tiles Mr. Grant needs to buy, more information is needed, such as the size of the area he needs to cover. The area of a single tile can be calculated using the formula Area = length × width. Since the tiles are squares, the length and width are the same, so if each side is 3 feet, then the area of a single tile is 9 square feet. If, for example, Mr. Grant needed to cover an area of 27 square feet, he would divide the total area by the area of a single tile: 27 ÷ 9 = 3, so he would need 3 tiles.

Solve for xxx. Write the smaller solution first, and the larger solution second. x^2 + 9x + 18 = 0x 2 +9x+18=0x, squared, plus, 9, x, plus, 18, equals, 0 \text{smaller }x =smaller x=start text, s, m, a, l, l, e, r, space, end text, x, equals \text{larger } x =larger x=start text, l, a, r, g, e, r, space, end text, x, equals
To solve the quadratic equation x^2 + 9x + 18 = 0, you'll have to find values of x that satisfy this equation.
To find the roots of the quadratic equation, we use the formula x = [-b±sqrt(b^2 -4ac)]/2a, where a, b, c are the coefficients of the quadratic equation of the form: ax^2 + bx + c = 0.
In our equation, we have:
a = 1 (coefficient of x^2)
b = 9 (coefficient of x)
c = 18 (constant term)
Substituting these values in our formula, we get:
x = [-9±sqrt((9)^2 - 4*1*18)] / 2*1,
x = [-9±sqrt(81 - 72)] / 2,
x = [-9±sqrt(9)] / 2,
x = [-9±3] / 2.
From here, we get two solutions:
For the smaller solution, we have: x = [-9 - 3] / 2 = -6.
For the larger solution, we have: x = [-9 + 3] / 2 = -3.
So, the solutions to the equation x^2 + 9x + 18 = 0 are x = -6 (for the smaller solution), and x = -3 (for the larger solution).
PLEASE ANSWER ASAP. What is the diagonal length of a photo frame with dimensions that are 24 cm x 7 cm?
A. 19 cm
B. 25 cm
C. 28 cm
D. 32 cm
Answer:
B
Step-by-step explanation:
The diagonal will become the hypotenuse of a right triangle, with the legs being 24 and 7.
Since it is a right triangle, we can use Pythagorean theorem
a^2+b^2=c^2
We know the legs: a and b, are 24 and 7, so we can substitute them in
24^2+7^2=c^2
Solve the exponents
576+49=c^2
Add
625=c^2
Take the square root of both sides
[tex]\sqrt{625}[/tex]=[tex]\sqrt{c^{2} }[/tex]
c=25
So, the diagonal will be 25 cm, or choice B

25cm or b

Answer:
the two packed because :
Step-by-step explanation:
first you need to find out the total of the two separated and for one it is £12.49 but for the second it is 50% off so 50% is a half so half of £12.49 is £6.25 so you now need to add them both together to find out how much two bottles cost separate which is £18.74. now you need to have a look see which costs less this is the two together in the pack so the answer is you would rather buy the two packed one because they are cheaper

Which better describes the data set, the mean or the median? Select the answer with the best explanation. A The median, because it is in the middle of the set. B The mean, because it is closer to most of the data values than the median is. C The mean, because it is the average of all the values of the set. D The median, because it is closer to most of the data values than the mean is.
Answer:
C
Step-by-step explanation:
The mean of the data describes the data set , because it is the average of all the values of the set
What is Mean?The mean value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values.
Mean = Sum of Values / Number of Values
Given data ,
Let the data set be represented as A
Now , the value of A is noted
And , the median of the data set is the middle term of the set
where the mean value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values
So , the average values of the set determines the data values as it is a compilation of all the data values
Hence , the mean of the data describes the set

What is the value of x?
Answer:
Step-by-step explanation:
a triangle = 180
Q = 180 - (90 + 45)
Q = 180 - 135
Q = 45
Step-by-step explanation:
With reference angle 60°
perpendicular (p) = 2√3
hypotenuse (h) = ?
We know
sin 60° = p/h
√3/2 = 2√3 / h
cross multiply
h =( 2√3 * 2)/ √3
therefore h = 4
So
Now
with reference angle 45°
perpendicular (p) = x
base (b) = 4
Now
tan 45° = p/b
1 = x / 4
Therefore x = 4

The graphed line shown below is y = negative 2 x minus 8.
On a coordinate plane, a line goes through (negative 4, 0) and (negative 2, negative 4).
Which equation, when graphed with the given equation, will form a system that has infinitely many solutions? y = negative 2 x minus 8.
y = negative (2 x + 8)
y = negative 2 (x minus 8)
y = negative 2 (x minus 4)
y = negative (negative 2 x + 8)
Answer:
A
Step-by-step explanation:
Our given equation is: y = -2x - 8
In order to have an equation with infinitely many solutions, it needs to be the same as the given equation.
Look at the answer choices:
A) y = -(2x + 8) = -2x - 8
This is the exact same equation, which means that any solutions for the given will also be solutions for this one. That means there will be infinitely many solutions.
B) y = -2(x - 8) = -2x + 16
We can tell this is definitely not the same as the given, so eliminate.
C) y = -2(x - 4) = -2x + 8
Again, this has a +8 instead of -8, so it's not the same and wrong.
D) y = -(-2x + 8) = 2x - 8
Here, we have positive 2 as the slope instead of -2, so it's not the same and wrong.
Thus, the answer is A.
Hope this helps!
