Use foil to explain how to find the product of (a+b)(a-b). Then describe a shortcut that you could use to get this product without using foil.
Answers
F- multiply the first two terms axa= a^2
O- multiply the two terms on the outside a x -b= -ab
I- multiply the two inner (middle) terms - b x a= ab
L- multiply the last variable in each term= b^2
A shortcut without using FOIL is called the difference of squares and can be rewrote as (a^2-b^2)
Firsts: a×a= a^2
Outers: a×-b= -ab
Inners: b×a= ab
Lasts: b×-b= -b^2
Combine -
a^2-ab+ab-b^2
= a^2-b^2
This particular pair of binomial brackets with a + and a - in them can be expanded with the difference of two squares:

Answer:

Step-by-step explanation:
We can change the sign of an exponent if we change sides. This means sign of exponent changes when we move the number (along with base) from numerator to denominator or from denominator to numerator.
So 10 to the power -1 will change to 10 to the power 1 if we take the whole thing to the denominator (steps shown below):

How can you solve problems involving equivalent expressions?
Answers
Since you didn’t give he specific questions I️ just do an example.
Say you’re trying to figure out x from 4x+5=2x+33
You basically just move the stuff around until all you have left on one side of the = is x so whatever you do from one side you do to the other.
4x+5=2x+33
-5 -5
4x =2x+28
-2x -2x
2x = 28
/2 /2
x = 14

pls dont answer if you dont know or you are not an expert
Answers
simple interest rate over 5 years = 1.5 x 5 = 7.5%
100% + 7.5% = 107.5%
107.5% = $19500
1% = 181.3953
100% = $18140.50
He needs to put in $18140.50 so that he can get $19,500 at the end of 5 years.

How is the following decimal number read?
28.9
A. Twenty and eight-nine tenths
B. Twenty-eight and nine hundredths
C. Twenty-eight and nine tenths
D. Twenty-eight nine
Answers
C) twenty-eight and nine tenths
Explanation:
We have two parts here, the whole number and the decimal part.
1- for the whole number, it is read normally as counting numbers. Therefore, 28 is read as twenty-eight
2- for the decimal part, it is read based on the place-value of the number. We know that the first number after the decimal point is in the tenth position. This means that 0.9 is read as nine tenths
Combining the two, we would conclude that 28.9 is read as twenty-eight and nine tenths
Hope this helps :)
Answer:
C. Twenty-eight and nine tenths.
Step-by-step explanation:
We have been given a decimal number [tex]28.9[/tex]. We are asked to choose the correct option that represents how to read our given decimal number.
Upon looking at our given decimal number we can see that it has one digit at tenth place that is 9, which represents that our number has 9 tenths.
The two digits before decimal are 2 (tens place) and 8 (ones place). These digits make 28.
Therefore, the given decimal number could be read as twenty-eight and nine tenths and option C is the correct choice.

B. 3.7 x 10^6
C. 3.7 x 10^4
D. 3.7 x 10^3
Answers
Hope this helps :D
Final answer:
To find out how many times more massive than the Sun a black hole with a mass of 7.36 x 10³⁶ kg is, divide its mass by the mass of the Sun which is approximately 1.99 x 10³⁰ kg. The answer is 3.7 x 10⁶ times more massive than the Sun.
Explanation:
Scientists believe that there is an extremely massive black hole at the center of the Milky Way. To find out how many times more massive than the Sun a black hole with a mass of 7.36 x 10³⁶ kg is, you can divide its mass by the mass of the Sun. So, 7.36 x 10³⁶ kg / 1.99 x 10³⁰ kg = 3.7 x 10⁶ times more massive than the Sun.
At a local fitness center, members pay an $8 membership fee and $3 for each aerobics class . Nonmembers pay $4 for each Aerobics class. For what number of aerobics classes will the cost for members & nonmembers be the same?
Answers
Since members pay $3 for each aerobics class, we can represent this part of the equation as 3c. Members also pay a one time $8 membership fee, so we just add the 8 to the 3c:
3c + 8
Since nonmembers pay $4 for each aerobics class, we can represent this part of the equation as 4c. They do not have to pay a one time membership fee, so our equation will just be:
4c
To determine when the cost (c) of the aerobics class will be the same for both members and nonmembers, we set the two equations equal to each other:
3c + 8 = 4c
Then, we solve for c. First, the variables must be on the same side of the equation. We can do this by subtracting 3c from both sides of the equation:
8 = 1c.
Last, we divide both sides by 1. So c = 8.
This means that the cost of classes will be the same for members and nonmembers at 8 classes. If we want to check our answer, we can plug 8 back into each equation:
3c + 8
= 3 ( 8 ) + 8
= 24 + 8
= 32
4c
= 4 ( 8 )
= 32

Percy is plotting points on a graph. The ratio of y-value to x-value is 2 to 3 for each point. What will be the x-value of a point with a y-value of 18?
Answers
Answer: Value of x = 27
Explanation:
Percy is plotting a coordinate on the graph.
Now the ratio of y-value to x-value is 2 to 3 for each point.
Suppose Value of is 3a and y value is 2a
So, the coordinate of the point is (3a,2a)
Now we find the x value of the coordinate when value of y is 18.
2a is same as 18
2a = 18
a = [tex] \frac{18}{2} [/tex]
a = 9.
Now find the x ordinate
put the value of a=9 into 3a
3a = 3(9) = 27
So the final answer is :
Value of x = 27 when value of y = 18

Answers
A snail moves 1/40 of a mile in 3/4 of an hour. If the snail continues at this pace, how far, in miles, does it move in one hour?
In [tex] \frac{3}{4} [/tex] hour snail moves [tex] \frac{1}{40} [/tex]miles
[tex] \frac{3}{4} hour = \frac{1}{40} [/tex] miles
Let us multiply by 4 on both sides, so that we can get the distance to be traveled in 1 hour.
So, [tex] \frac{3*4}{4} hour=\frac{1*4}{40} [/tex] miles
[tex] \frac{3*1}{1} hour=\frac{4}{40} [/tex] miles
Now to get distance in 1 hour, Let us divide by 3 on both sides
[tex] \frac{3}{3} hour=\frac{1}{10*3} [/tex] miles
[tex] \frac{1}{1} hour=\frac{1}{30} [/tex] miles
In 1 hour, the snail travels [tex] \frac{1}{30} [/tex]miles

The given question is a typical example of mathematical puzzles. Mathematical puzzles are mathematical problem given to pupils, students for recreational experience and more.
Further ExplanationMathematical puzzles further enhance the creativity of students, as it deals with their logical reasoning.
Mathematical puzzles also has do with the practical usage of order of operations i.e. BODMAS (which is an acronym of Bracket, Of, Division, Multiplication, Addition, Subtraction) to derive solutions for existing problems.
It can be observed from the above given mathematical puzzle expression that Multiplication and Addition are in use in that order.
The two figures are multiplied and added together and then placed together to derive a final
5 + 3 = 158
5 x 3 ~ 5 + 3 = 15 ~ 8 = 158
9 + 1 = 910
9 x 1 ~ 9 + 1 = 9 ~ 10 = 910
8 + 6 = 4814
8 x 6 ~ 8 + 6 = 48 ~ 14 = 4814
4 + 4 = 168
4 x 4 ~ 4 + 4 = 16 ~ 8 = 168
Therefore,
7 + 3 = 2110
7 x 3 ~ 7 + 3 = 21 ~ 10 = 2110
