What is the surface area of the box? use your answer to problem 2 to write an equation
sammy [17]

Answer:

S=2lw+2lh+2wh

Step-by-step explanation:

If we consider the structure of a box with length l, width w, and height h, we may note that it is formed from six rectangular faces. The bottom and top faces are rectangles with sides of length l and w. Two of the side faces have side lengths l and h. And the remaining two side faces have side lengths w and h.

As the area of a rectangle is the product of its side lengths, we can put this together to get the surface area S of the box as

S=2lw+2lh+2wh

A line has a slope of –3/2 and has a y-intercept of 3. What is the x-intercept of the line?
Maslowich

Answer:

The x-intercept is (2, 0).

Step-by-step explanation:

First write the equation of this line:  y = (-3/2)x + 3.

At the x-intercept, y = 0.  So, we set the above equation equal to 0 and solve for the x-intercept:

0 = (-3/2)x + 3, or

(3/2)x = 3, or x/2 = 1.  Thus, x = 2.

The x-intercept is (2, 0).

j = 34

34 + p > 175 <== ur inequality

p > 175 - 34

p > 141.......so she spent at least 141.01...because it has to be greater then 141...but cant be equal.
