Step-by-step explanation:
Answer:
x^2+x-2
this is the answer bc the 2nd parentheses is being multiplied by the negative sign meaning you need to subtract it from the 1st parentheses.
Answer:
x=-3
Step-by-step explanation:
Answer:
3.5 m
Step-by-step explanation:
Use Pythagorean theorem to find the distance (d) the distance goes up the wall = adjacent to the angle 75° that is formed with the wall.
Length of ladder = the hypothenuse = 13.5 m
Thus, we would use:
Cos75 = adjacent/hypothenuse
Cos 75 = d/13.5
Multiply both sides by 13.5
13.5*cos(75) = d
13.5*0.2588 = d
3.4938 = d
d ≈ 3.5 m (nearest tenth)
