The answer is 290 inches squared.
The surface area is = the sum of all sides. There are 4 sides that equal 60 (60 x 4 = 240), and 2 sides that equal 25 (25 x 2 = 50), the surface area is equal to 240 + 50 which equals 290.

Answer:

290 in^2

Step-by-step explanation:

So what you do is you use the formula of the surface area of a rectangle which is SA=2lw+2lh+2hw.

The length=5. The width=5. The height=12.

You put those numbers into the formula.

2(5)(5)+2(5)(12)+2(12)(5)=290 in^2.

Write an equation for the line that passes through (4,-6) and (-7,-6). Is the line parallel or perpendicular to the y-axis?

alisha [4.7K]

Answer:

y = -6, perpendicular

Step-by-step explanation:

You can use the points to find the slope of the line:

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} =\frac{-6-(-6)}{-7-4} =\frac{-6+6}{-7-4}=\frac{0}{-11}=0$

Then, using point-slope form, choose one set of coordinates to use for y1 and x1:

$y-y_{1}=m(x-x_{1})$

$y-(-6)=0(x-4)$

$y+6=0$

$y=-6$

Since the slope of the line is zero, it's a horizontal line. The y-axis is a vertical line, which means that the line is perpendicular to the y-axis.
