You want to use PEMDAS to solve this problem.
So we do the parentheses first (4-2) = 2
Then you would do the exponent next
2 to the 5th power is 32
2 to the 3rd power is 8
(2) to the 4th power is 16
32 / 8 • 16
Then we want to do Multiplication and division from what ever comes first so in this case 32/8, which will equal 4 then we multiple 4 with 16 making the answer 64
This is the question that's gonna put me over the top and make me a Brainly Genius. Of course working for free doing middle school math homework doesn't really sound like a genius, but I'm doing it anyway.
This one is the Pythagorean Theorem of course:
The Shakespeare Quadratic Formula (2b or -2b) is a little shortcut for the quadratic formula when the middle term is even.
So we get
The minus root is less than -6 giving negative sides, so we reject it and conclude
Choice C

If you want the strip around the mat:
x=strip of mat
2(20+2x)+2(15+2x)=102
Distribute
40+4x+30+4x=102
Combine like terms
70+8x=102
Subtract 70
8x=32
Divide by 8
x=4
If you want the whole width of the mat:
w=15+x
w=15+2*4
w=23
I don't understand................
Answer: I don't see that you have a diagram of the swimming pool or any given side measures but assuming it is a rectangle, the algebraic expression would be 2(L+W) where L is the length and W is the width.
Step-by-Step Explanation: So when you are finding the perimeter, you are finding the length of the space surrounding something. So you would add up the length of all its sides to find it. In a rectangle, opposite sides are equal, therefore the length will be equal to the side opposite to it and the width will also be equal to the side opposite to it. So if you were to write the expression like that, you would get L+L+W+W, which can be simplified to 2L+2W, or just 2(L+W).
