Step-by-step explanation:
The angles (8x + 28) and (4x - 7) are supplementary to each other so we can write
or

Also, note that the angle (4x - 7) and
are vertical angles, which means that they are equal to each other. Therefore,

Area = (base * height) / 2
60 = (12 * h) / 2
120 = 12h
h=10 yards
Answer:
5. (2x-3)(3x+2)
6.(x-8)(2x-5)
7.(5x-2)(2x+1)
8.(4x+3)(x+3)
Step-by-step explanation:
example on how to solve this in not how you solve your questions
2x times x = 2x2
2x times 2 = 4x
5 times x = 5x
5 times 2 = 10
The factors are (2x + 5) and (x + 2), so 2x2 + 9x + 10 = (2x + 5) × (x + 2)
4x and 5x are interchangeable, so you could put 5x in the first row and 4x in the second row and still get the same answer.
Divide the numerator and denominator
D seems to be right answer
