4x + 4y
Step-by-step explanation:
5y - 8x - y + 12x
4y + 4x
Answer:
6 miles
Step-by-step explanation:
3+1/2+2+1/2=6miles
We are tasked to solve for the ratio of the two boxes. Boxes are cubes. We can use the formula in solving the surface area of the box as shown below:
Surface Area of Cube = 6a² where "a" is the length of the side.
For smaller box:
Area= 6(12)²=864
Area =864
For the larger box:
Area = 6(18)²
Area=1944
Then, the ratio is:
Area smaller box/Area larger box =864/1944
Ratio=4:9
Y-y1=m(x-x1)
slope=m
point is (x1,y1)
slope=3
point is (-6,-1)
y-(-1)=3(x-(-6))
y+1=3(x+6)
Steps To Solve:
x² + 6 = 10
~Subtract 6 to both sides
x² + 6 - 6 = 10 - 6
~Simplify
x² = 4
~Take square root of 4
x² = ±√4
~Simplify
x = -2 or x = 2
Best of Luck!
