B = 2x+4
H = 3x-5
A = bh
= (2x+4)(3x-5)
= (2x)(3x)+(2x)(-5)+(4)(3x)+(4)(-5)
= 6x^2 - 10x + 12x - 20
= 6x^2 + 2x - 20
So the answer is A (6x^2 + 2x - 20) (i think)

tan37=r/8
r=8tan37
r≈6 in rise per step (to nearest whole inch)
2b
11*12/6=22 steps needed to climb the 11 ft to the entrance
...
3a
tanα=14/20
α=arctan(7/10)
α≈35° (to nearest whole degree)
..
3b
tanα=21/17
α=arctan(21/17)
α≈51° (to nearest degree)
Step-by-step explanation:
3x + 12 - 2x + 8 + 5x
Solving like terms
x + 20 + 5x
20 + 6x
20 / 6 = x
Answer: 31.57
Step-by-step explanation: If x is 37, that would mean 0.11 x 37 and that equals 4.07. Then you would add 27.50 and 4.07 and get 31.57.
