Answer:
[2,6]
Step-by-step explanation:
3x+5y=36
5x-4=y
3x+5(5x-4)=36
3x+25x-20=36
28x-20=36
28x=56
x=2
5x-4=y
5*2-4=y
10-4=y
6=y
9514 1404 393
Answer:
486 square units
Step-by-step explanation:
Use the surface area formula with the given numbers.
SA = 2(LW +H(L +W))
SA = 2(12·6 +9.5(12 +6)) = 2(72 +9.5(18)) = 486
The surface area of the box is 486 square units.
The answer is a, it adds one block
<h3>The surface area of cube is 162.24 square inches</h3>
<em><u>Solution:</u></em>
<em><u>The surface area of cube is given as:</u></em>
![Surface\ Area = 6s^2](https://tex.z-dn.net/?f=Surface%5C%20Area%20%3D%206s%5E2)
Where,
"s" is the length of each side of cube
From given,
s = 5.2 inches
Therefore,
![Surface\ Area = 6 \times 5.2^2\\\\Surface\ Area = 6 \times 27.04\\\\Surface\ Area = 162.24](https://tex.z-dn.net/?f=Surface%5C%20Area%20%3D%206%20%5Ctimes%205.2%5E2%5C%5C%5C%5CSurface%5C%20Area%20%3D%20%206%20%5Ctimes%2027.04%5C%5C%5C%5CSurface%5C%20Area%20%3D%20162.24)
Thus the surface area of cube is 162.24 square inches
