Answer:

0

Step-by-step explanation:

Apply Only the Outside and Inside Method of the Foil Method.

7 \times  -  \frac{1}{2}  =  - 3.5x

\frac{1}{2}  \times 7x = 3.5x

Add them together

- 3.5x + 3.5x = 0

So our b value is 0.

What is the value of this expression when a = 2 and b = -3 ? a^3 - b^3 / 5
saveliy_v [14]

Answer:

13 2/5

Step-by-step explanation:

a = 2 and b = -3

so the question asks whats.... a^3 - b^3/5

First we plug in the values of a and b

(2)^3 - (-3)^3 /5

Now we solve the ones in paranthesis first

(2)^3 = 8 because 2×2×2 and

-(-3)^3 forget about the - outside the parenthesis so

(-3)^3 = (-27) because (-3)×(-3)×(-3)

now we put it back together

8 -(-27)/5

the two minus become plus so

8 + 27/5

Now we solve it like fractions

8 and 27/5

simplify

13 and 2/5

Hope that helps!
