(x+9)(x+8) = x^2 +17x + 72
(x- 7)(x+8) = x^2 + x - 72
(x- 5)(x- 6) = x^2 -11x + 30
(2x + 3)(3x+2) = 6x^2 + 13x +6
(5x - 4)(2x-5) = 10x^2 - 33x + 20
(x-4)^2 = x^2 -8x + 16
(2x+1)^2 = 4x^2 +4x + 1
(4x+3)(4x-3) = 16x^2 - 9
The second description is not suitable.
It should be "simplify the terms" sice you are just adding 36 and -20.
Consider the given expression,

Apply the distributive property,

Combine like terms,

Subtract 20 from both sides,

Divide both sides by 27,
Answer:
h(5)=23
Step-by-step explanation:
<u>So the equation to find the sum of interior angles is
, with n = number of sides.</u> In this case, this is an octagon (8 sided polygon), so plug in 8 into the equation to solve:

<u>The sum of the interior angles is 1080°</u>
The derivative of a variable raised to exponent of n, x^n is equal to the product of n and x raised to exponent of n-1.
d(x^n) = (n)(x^n-1)
So, from the given
d(9x + 5) = (1)(9x^1-0) + 5(0)
= 9
The given value of x is irrelevant to this item because the derivative does not contain any variable x.
