Answer:
11 units
Step-by-step explanation:
To calculate CD use the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = C(- 4, 6) and (x₂, y₂ ) = D(- 4, - 5)
CD =
=
= =
= 11
Answer:
The ladder should be 34 feet long.
Step-by-step explanation:
The height of the spotlight above ground = 30 feet
The base of the ladder will be = 16 feet from the base of house
We can easily assume this to be a right triangle with perpendicular as 30 feet and base as 16 feet and we have to find the hypotenuse.
Lets say the length of the ladder or hypotenuse is = x
We will apply Pythagoras theorem here.
=>
=>
=>
So, x = 34
Hence, the ladder should be 34 feet long.
The answer is 7x + 3
First, you have 3x-1 + 2x+1
Combine like terms and the 1’s cancel each other out. You are left with 5x.
Then, you add x+2 + x+1
Combine like terms and you have 2x+3
Add 5x + 2x+3 and you have 7x +3
I’m bad at explaining, so here are the steps.
