-4z is the answer I believe
Given the information, we have the following:
since the distance from each boundary of the tennis court to the fence is the same (x feet), then we have:
therefore, the expression that gives the are of the entire surface inside the fence is A=(36+2x)(78+2x)
1.015873015873016 to the nearest tenth is 1.02. The tenth place is the second number to the left of the decimal and you would round up because the third number is at least five.
I hope this helps!
33/100 as a decimal is 0.33
3x - 9y - 5x - 7y
Combine like terms
( 3x + - 5x ) + ( - 9y + - 7y )
= - 2x - 16y
