Answer:
x=2.5
Step-by-step explanation:
x(2)-8×+15=0 combine like terms
-6x+15=0 subtract 15 from both sides
-6×=-15 divide by -6 on both sides
2x -8x+15=0
-6x+15=0
-6x= 15
x= 5/2
r=9/2 or 4.5
First of all our goal is to get R by itself
by cross multiplying we get,
(r+3)*3=5r
by distributive property we get
3r+9=5r
substracting 3r from both sides we get
9=2r
by dividing by 2 in both sides we get

C, D, E
l×w×h
Length and width are n
Height is 6
Plug them into the equation, the order can be changed. Also, n^2 is the same as n×n. Hope this helped you.
