A square. A square is a quadrilateral with 4 sides with the same lenght.
Answer:
see below
Step-by-step explanation:
SA of a cylinder = 2πr² +2πrh
________________________ = 2πr²/4πr² + 2πrh/4πr² =1/2 +h/2r
SA of a sphere = 4πr²
The answer is 350 because 10 * 7 = 70 and 70 * 5 = 350
Answer:
27+4x+8y
or
4x+8y+27 ( I can reorder this a few different ways. I don't know what your choices are)
Step-by-step explanation:
11+4(x+2y+4)
We can apply distributive property to the 4(x+2y+4), this will give us 4x+8y+16.
Bring down the 11+ and we have 11+4x+8y+16.
The only like terms we have is 11 and 16. So reorder using commutative property and get 11+16+4x+8y.
I'm going to simplify the 11+16 part which gives us 27.
In the end we have 27+4x+8y.
Let me line up so it is all nice and neat:
11+4(x+2y+4)
11+4x+8y+16
11+16+4x+8y
27+4x+8y
Answer: the answer is 55°
Step-by-step explanation:
You equal the equations out and the number you get from doing that is the fill in for x and the you solve one of the equations replacing x with the number gotten
