Helena wants to paint a box in the shape of a cube with sides that are 18 inches long. what is the surface area that Helena will
yan [13]

Answer:

1944 Inches Squared

Step-by-step explanation:

Surface area Formula for a Cube:

A = 6a^2

The "edge", which is also the side, is 18 inches.

a = 18

Solve the formula.

A= 6a^2 = 6(18)^2 = 6 * 18^2\\18^2 = 324\\324 * 6 = 1944\\A=1944

The cube's surface area should be 1944 square inches.

Upstream: 14 - 4 = 10. Miles per hour.
16 miles = 1.6 hours.

Downstream: 14 + 4 = 18.
16 miles = 16/18 = 8/9 or 0.888 of an hour.

Rewrite the following equation in slope-intercept form. 6x − 14y = -3 Write your answer using integers, proper fractions, and im
Alex17521 [72]
Answer:
y = (3/7) x + (3/14)

Explanation:
The slope-intercept form has the following formula:
y = mx + c
where:
m is the slope
c is the y-intercept

The given is:
6x - 14y = -3

To get in the slope-intercept form, we need to isolate the y as follows:
6x - 14y = -3
14y = 6x + 3
y = (6/14)x + (3/14)
y = (3/7) x + (3/14)

Hope this helps :)
