5(x+y)= 20+ 3x
5x+5y=20+3x
5x+5y-3x=20+3x-3x
2x+5y=20
2x+5y-2x=20-2x
5y=-2x+20
5y/5=-2x/5+20/5
y=-2/5x+4
ANSWER: y=-2/5x+4
The answer is 52 if you are looking for the answer to 2x2x13=? then it is 52. Otherwise idk what you are asking.
Answer:
125 ft²
Step-by-step explanation:
We know that that surface area of the triangular prism that will be covered with insulation is equal to the area of the two triangular faces, plus the two lateral rectangular faces.
So you get:
SA = 2 [
(15)(15)] + 2 [(30)(15)] = 1,125 ft²
A = 90 degrees
B = 50 degrees
D = 140 degrees
E = 40 degrees
HOPE THIS HELPS!
