Answer:
6x^2-6x-6
Step-by-step explanation:
(x^2-3x+2)+(5x^2-3x-8)
x^2+5x^2-3x+(-3x)+2+(-8)
6x^2-3x-3x+2-8
6x^2-6x+2-8
6x^2-6x-6
Answer:
126.2 meters
Step-by-step explanation:
A trapezoid's area is found using the formula A = 1/2 (a+b)h where a and b are the two bases. Substitute A = 12,052.1, a = 82.4 and b=108.6. Then solve for h.
A = 0.5(a+b)h
12,052.1 = 0.5(82.4 + 108.6)*h
12,052.1 = 0.5(191)h
12,052.1 = 95.5h
126.2 = h
We have the expression
, note that both terms have the factor 2x, if we factor this out, we are left with:
2x(4x + 5)
If you redistribute it you can see that it equals
