We will use the distributive property. -4 times 9z=-36z -4 times -2=8 so we have -36z+8 as our answer
Answer:
65+42*(n-1)
Step-by-step explanation:
aₙ = 65+42*(n-1)
65, 107, 149, 191, .....
4+3 = 7
7^2 +6^2
49+36 = 85
Radical85 = 9.21
So x will be 3.9
I think it’s 5 but i’m not sure lol
Answer:
15.5 ft
Step-by-step explanation:
The geometry of the problem can be modeled by a right triangle with hypotenuse 16 ft and one side length of 4 ft. If x represents the height of the ladder on the building, then the Pythagorean theorem tells us ...
x^2 + (4 ft)^2 = (16 ft)^2
x^2 = 240 ft^2 . . . . . . subtract 16 ft^2
x ≈ 15.5 ft . . . . . . . . . . take the square root
The top of the ladder is about 15.5 ft above the ground.
