Since they both equal y, set the equations equal to each other: 12x + 39 = 9x, simplify
1) 39 = -3x
2) -13 = x
Answer:
y = a - b(5) i think that's it

Answer:
2±1\2x
Step-by-step explanation:
[4±x]1\2
we will start by opening the brackets
[4]1\2=2
[x]1\2=1\2x
2±1\2x
hope am right
Answer:
2.83 inches
Step-by-step explanation:
The formula for surface area of cube = 6s²
Where
s = side length of cube
S.A = 6s²
s² = S.A/6
s = √S.A /6
For cube a
Surface area = 1200 in²
Hence,
side length = √1200/6
Side length = √200
= 14.14 inches
For cube b
Surface area = 768 in²
Hence,
side length = √768/6
Side length = √128
= 11.13 inches
How much longer is the side of a cube with a surface area of 1,200 square inches than a cube with the surface area of 768 square inches?
Therefore,
14.14 inches - 11.13 inches
= 2.83 inches
