Answer:
yes,yes,no,yes
Step-by-step explanation:
Hello there,
The equation that we have to factor is as follows:
2x² + 3x - 54
In order to factor this we first multiply (-54) by 2 and try to find two factor pairs that can be add up to 3.
For this we would use 12 * -9 which gives you -108 when multiplied and when added you would get 3.
2x² + 12x - 9x -54
2x(x + 6) -9(x +6)
(2x - 9) (x + 6)
Now the factor pairs would be: (2x - 9)(x + 6)
Hope I helped,

Answer:
B
Step-by-step explanation:
Use the formula for finding the area of a cylinder - V = (pi)r^2h
Add in the numbers you were given:
V = (22/7) 5^2 (175)
The volume is A) 13,750 ft3
sin(x) = ⁴/₅
sin⁻¹[sin(x)] = sin⁻¹(⁴/₅)
x ≈ 53.13
cos(90 - x) = cos(90)cos(x) + sin(90)sin(x)
cos(90 - 53.13) = cos(90)cos(53.13) + sin(90)sin(53.13)
cos(36.87) = 0cos(53.13) + sin(53.13)
cos(36.87) = sin(53.13)
cos(36.87) = cos(90 - 53.13)
cos(36.87) = cos(36.87)
