When it tells you to find h(2), that means you plug in 2 for x.
If 2x^3 (to the third power)
2(2)^3-3

1. PEMDAS, exponents first
2^3=8

2. multiply
8x2=16

3. subtract
16-3=13

Hope this helps!

Help please! I do not exactly understand how to do this. Thanks!
Radda [10]

X and Y are supplementary, that means X + Y = 180.

But we have, X  = Y +24, then

X + Y = Y + 24 + Y = 2Y + 24 = 180

Then

2Y = 156

Y = 78

Then X = 78 + 24 = 102.

(x - 5)(x^2 + 4x - 2)
n200080 [17]

Distribute sum groups

x(x^2 + 4x - 2) - 5(x^2 + 4x - 2)

Distribute

x^3 + 4x^2 - 2x - 5(x^2 + 4x - 2)

Distribute

x^3 + 4x^2 - 2x - (5x^2 + 20x - 10)

Simplify brackets

x^3 + 4x^2 - 2x - 5x^2 - 20x + 10

Collect like terms

x^3 + (4x^2 - 5x^2) + (-2x - 20x) + 10

Simplify

<u>x^3 - x^2 - 22x + 10</u>
