A cardboard box is shaped like a cube. The length of each side is 15 inches.
chubhunter [2.5K]
<h3>Answer: 1350 square inches</h3>

Work Shown:

s = side length = 15 inches

SA = surface area of the cube

SA = 6s^2

SA = 6*15^2

SA = 6*225

SA = 1350

The surface area is 1350 square inches.

Note the formula has us compute the area of each square face, which is s*s = s^2. Then we multiply by 6 since there are 6 identical square faces on the cube.

HELP format is y=mx+b!!!!
Gekata [30.6K]

Answer:

y = - 3x - 3

Step-by-step explanation:

the equation of a linear function in slope- intercept form is

y = mx + b ( m is the slope and b the y- intercept )

To calculate m use the slope formula

m = (y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (- 2, 3) and (x₂, y₂ ) = (6, -21) ← 2 points from the table

m = \frac{-21-3}{6+2} = \frac{-24}{8} = - 3

y = - 3x + b ← is the partial equation

To find b substitute any other point from the table into the partial equation

using (2, - 9), then

- 9 = - 6 + b ⇒ b = - 9 + 6 = - 3

y = - 3x - 3 ← linear relationship
