So y=9....
9=-3x+6
3=-3x
x=-1
so answer.....-1,9.....that is C
Answer:
Step-by-step explanation:
2X+4)+(2X+4)+X+X=38
Lets add our X's and then add our whole numbers. 6X+8=38
Lets work our sentence by subtracting 8 from each side of the equal sign.
6X+8–8=38–8
6X=30
Lets divide each side by 6.
6X/6=30/6
X=5 now lets prove 5 is X.
(2×5+4)+(2×5+4)+5+5=38
(14)+(14)+5+5=38
28+10=38
38=38
X is equal to 5.
Answer:
62
Step-by-step explanation:
surface area of a rectangular prism = 2lw + 2lh + 2wh
Where l = length, w = width and h = height
The box has the following dimensions
length = 5 in
width = 3 in
height 2 in
Using these dimensions, we plug in the values into the formula
![SA=2(5*3)+2(5*2)+2(3*2)\\5*3=15\\15*2=30\\5*2=10\\10*2=20\\3*2=6\\6*2=12\\SA=30+20+12\\30+20+12=62](https://tex.z-dn.net/?f=SA%3D2%285%2A3%29%2B2%285%2A2%29%2B2%283%2A2%29%5C%5C5%2A3%3D15%5C%5C15%2A2%3D30%5C%5C5%2A2%3D10%5C%5C10%2A2%3D20%5C%5C3%2A2%3D6%5C%5C6%2A2%3D12%5C%5CSA%3D30%2B20%2B12%5C%5C30%2B20%2B12%3D62)
Hence, the surface area = 62
