Answer:
x=-7
Step-by-step explanation:
The sum of the angles of a triangle are 180 degrees
40 + x+57 + 90 =180
Combine like terms
187 +x = 180
Subtract 187 from each side
187-187 +x = 180-187
x = -7
1. 24 times 18 times 9 to find area of the walls.
2. Take 3888 and divide that by 4 to get how much you need.
3. Answer is 972
So your final answer should be 972 square yards are needed for 4 walls.
Hope this helped you!
Have a great day.
I'd say what you would have to do is multiply 22 by 90% which is written like this:
0.9
What you will get when you put it into the calculator will be hours.minutes
Hope this helps!!(:
Answer:
4.4
Step-by-step explanation:
Answer:
144, 36, 9, 2 
Step-by-step explanation:
The recursive formula allows us to find a term in a sequence from the previous term.
Given
= 
Given the fourth term we require to work back to the third term , second and so on. Rearrange the formula to give
Multiply both sides by 4, then
= 4
Given a₄ = 2 , then
a₃ = 4 × a₄ = 4 × 2 = 9
a₂ = 4 × a₃ = 4 × 9 = 36
a₁ = 4 × a₂ = 4 × 36 = 144
