Answer:
Eh you got 3 wrong
Step-by-step explanation:
!! You got wrong !! First picture the answer is A b/c a function is when the X value only has 1 Y value assigned to it.
-------------
!! You got wrong !! The second picture, the answer is 35 T-Shirts
12T + 25S = 795
T - 20 = S
12T + 25(T - 20) = 795
12T + 25T - 500 = 795
37T = 1295
T = 35

!! You got wrong too !! First one has a solution of 0. The answer is the last answer choice.
---------------
You got this one correct, it is (2,3)
I hope this helps you

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 :)
Volume = length x Base x height
3240 = 18 x 12 x H
3240 = 216 x H
H = 3240 / 216 = 15 inches
