Answer:
y+yz is: 
Step-by-step explanation:
Given expressions are:

The given expressions are polynomials and we have to find the value of y+yz
First of all, we will find the product of y and z
We will use the distribution to find the product.

The next step is to add y and yz

The answer is not one of the options which i assume might be a typing mistake.
Hence,
y+yz is: 
P=2l +2w to find w use Pythagorean theorem
25^2 -24^2= w^2
625-576=w^2
w=7
2l +2w: l=24 w=7
24+24+7+7=62
Perimeter=62 cm
B * 3 < 140
B being the number of books Frank owns. Because tripling the amount of books he owns is still less than the amount of book Emily owns, b*3 has to be less than 140
