I know this isn't an answer but I've totally borrowed your profile pic and I hope you don't mind.. xD
Answer:
FALSE
Integer are set of positive numbers, negative numbers and zero but not fractions.
Answer:
The value of z is 1.
Step-by-step explanation:
Given:

We need to solve the problem using distributive property.
Solution:
For the given equation we will apply distributive property;
By Definition of Distributive property which states that;
"The distributive property lets you multiply a sum by multiplying each addend separately and then add the products."
example = 
So we get;

Now by using Subtraction property we will subtract both side by 1050 we get;

Now Dividing both side by 21 by using Division property we get;

Hence The value of z is 1.
Answer:
Longer side is 75 feet, shorter side is 50 feet.
Step-by-step explanation:
Let l be the length of the longer side and w be the length of the shorter side.
2l + 2w = 250, which simplifies to
l + w = 125. Solving for w, we have
w = 125 - l.
lw = l(125-l) = 3750


l = 75, w = 50
