Answer:

Tamara incorrectly factored the whole expression.

Step-by-step explanation:

Note that

•21x=3·7·x;

•56xy=2·2·2·7·x·y.

Mark in bold all common factors, then GCF(21x,56xy)=7·x=7x.

Thus,

21x+56xy=7x(3+8y).

Hence, Tamara correctly found the GCF of numbers 21 and 56, but incorrectly factored the whole expression.

Evaluate the expression when x = 8 and y = 1.
Rzqust [24]
The answer should be 4.

First, simplify \frac{8}{2} to 4. Your problem should look like: 4 x 1. 
Second, multiply. 4 x 1 = 4 so that is your answer.

Also, 
to start the equation up, make sure to add in the numbers in replace for the letters. Your problem to start with should look like: \frac{8}{2(1)}.

So to solve it the equation is a squared plus b squared = c squared. So you square a and b. Then do the square root of that and should get c. C is always the largest side. C is opposite from a 90 degree angle . Hope this helps you answer your question.

9500-8500 = 1000

Divide by the original amount

1000/8500=.117647059

Multiply by 100% to get in percent form
