Just download photo math, it’s super easy and the answers are always right
Right away the shape of the graph looks like a parabola which is a dead give away that the equation has to have an exponent in it leaving #1 as your only option. plug in a few numbers to proof like (5,393) and (10,1518)
Answer:
If Kareem were to work for 5 hours, she would get paid $45.
Step-by-step explanation:
If she gets paid $72 for working 8 hours, you would need to find how much she gets paid per hour by doing 
.
Which then gives you $9 per hour, so then all you need to do is multiply $9 by the number of hours which in this case is 5 to get the answer of $45.
So given a rectangle
sides are
_<u>x</u>_
x-5|__|x-5
x
the perimeter is 90 inches
perimeter is
x + x + (x-5) + (x-5) = 90
combine like terms
2x + 2(x-5) = 90
distribute
2x + 2x-10 = 90
combine like terms
4x - 10 = 90
add 10 to both sides
4x= 100
divide both sides by 4
x = 25
now to find the length of a side
x is 25
and x-5 is 20
to check and see if that's right:
25 + 25 + 20 + 20 =?= 90
50 + 40 =?=
90 = 90
Now to find the area
A = b * h
so
x * (x-5)
substitute
25* 20
500
The area of the rectangle is 500
Hope this helps :)
