Answer:
34
Step-by-step explanation:
(10)(4)−(4)(3)−2x−6x+8+(−3)(4)+(6)(3)−(2)(2)+8x−4
= 40+−12+−2x+−6x+8+−12+18+−4+8x+−4
Combine like terms:
= 40+−12+−2x+−6x+8+−12+18+−4+8x+−4
= (−2x+−6x+8x)+(40+−12+8+−12+18+−4+−4)
= 34
Angle of elevation is 37°
<u>Step-by-step explanation:</u>
As we have the opposite side 75 ft to the angle and the hypotenuse 125 ft, we can find the sine value as,
sin θ = opp/ hyp
= 75/125
= 0.6
θ = sin⁻¹ (0.6) = 36.9°≈ 37°
So angle of elevation is 37°.

Answer:
n≥-5
Step-by-step explanation:
-3n+2≥-4n-3
add 4n on both sides
n+2≥-3
subtract 2 on both sides
n≥-5
