The first blank is 17
2nd blank is 85
3rd blank is 15
wat happened is
C=paid-costofpizzas
paid=100
costofpizzas=number of pizzas times cost per pizza
costofpizzas=5 times 17
so
C=100-5 times 17
C=100-85
C=15
change=$15

Answer:
Step-by-step explanation:
- Its close circle because the number is included
The main rule we use in this exercise is
![( \sqrt{a} ) ^{m} =( a^{ \frac{1}{2}} )^{m} = a^{ \frac{1}{2}*m}=a^{ \frac{m}{2}}](https://tex.z-dn.net/?f=%28%20%5Csqrt%7Ba%7D%20%29%20%5E%7Bm%7D%20%3D%28%20a%5E%7B%20%5Cfrac%7B1%7D%7B2%7D%7D%20%29%5E%7Bm%7D%20%3D%20a%5E%7B%20%5Cfrac%7B1%7D%7B2%7D%2Am%7D%3Da%5E%7B%20%5Cfrac%7Bm%7D%7B2%7D%7D)
and the more general case:
![( \sqrt[n]{a} ) ^{m} =( a^{ \frac{1}{n}} )^{m} = a^{ \frac{1}{n}*m}=a^{ \frac{m}{n}}](https://tex.z-dn.net/?f=%28%20%20%5Csqrt%5Bn%5D%7Ba%7D%20%20%29%20%5E%7Bm%7D%20%3D%28%20a%5E%7B%20%5Cfrac%7B1%7D%7Bn%7D%7D%20%29%5E%7Bm%7D%20%3D%20a%5E%7B%20%5Cfrac%7B1%7D%7Bn%7D%2Am%7D%3Da%5E%7B%20%5Cfrac%7Bm%7D%7Bn%7D%7D)
Using these rules, we make all the indices, or exponents, look like
![a^{ \frac{m}{n}}](https://tex.z-dn.net/?f=a%5E%7B%20%5Cfrac%7Bm%7D%7Bn%7D%7D)
, and compare them to each other.

Formula for trapezoid
A=h*(b1+b2)/2,
b1 an db2 are the two lengths of the sides
152 = 16*(b1+6)/2 = 8*(b1+6)=8*b1+48--> 8*b1=104, b1 = 104/8=13
A = 16*(6+13)/2=16*9.5=152
