Answer:
it is 4 if you needed which of the 2
Simplify the following polynomial expression:
(5x^4 - 9x^3 + 7x -1) + ( -8x^4 + 4x^2 - 3x + 2) - ( -4x^3 + 5x -1) (2x - 7)
Lets Simplify Your Equation, Step by Step:
(5x^4 - 9x^3 + 7x -1) + ( -8x^4 + 4x^2 - 3x + 2) - ( -4x^3 + 5x -1) (2x - 7)
Solution: ===> 5x^4 − 37x^3 − 6x^2 + 41x − 6 = 0
Distribute:
= 5x^4 + -9x^3 +7x + −1 + −8x^4 + 4x^2 + −3x + 2 + 8x^4 + −28x^3 + −10x^2 + 37x + −7
Combine Like Terms:
= 5x^4 + −9x^3 +7x + −1 + −8x^4 + 4x^2 + −3x + 2 + 8x^4 + −28x^3 + −10x^2 + 37x + −7
= (5x^4 + −8x^4 +8x^4) + (−9x^3 + −28x^3) +(4x^2+ −10x^2) +(7x + −3x + 37x)+(−1 + 2 + −7)
= 5x^4 + −37x^3 + −6x^2 + 41x + − 6
Hence, Answer:
= 5x^4 −37x^3 −6x^2 + 41x − 6 = 0

The surface area of the trapezoidal prism is: 4,190 in.².
<h3>What is the Surface Area of a Trapezoidal Prism?</h3>
Surface area = (b1+b2)h + PH, where:
- Length of the base of the trapezoid (b1) = 20 in.
- Length of the base of the trapezoid (b2) = 60 in.
- Height of the trapezoid (h) = 15 in.
- Perimeter of the trapezoid (P) = 60 + 25 + 20 25 = 130 in.
- Height of the prism (H) = 23 in.
Plug in the values
Surface area = (b1+b2)h + PH = (20 + 60)15 + (130)(23)
Surface area = 4,190 in.²
