Find the value of x that will make l and m 7x-7, 4x+14

ohaa [14]

Answer:
x = 7

Explanation:
We are given that:
l = 7x - 7
m = 4x + 14

We want to have:
l = m

Therefore, we will simply equate the two equations and solve for x as follows:
7x - 7 = 4x + 14
7x - 7 - 4x = 4x + 14 - 4x
3x - 7 = 14
3x - 7 + 7 = 14 + 7
3x = 21
x = $\frac{21}{3}$
x = 7

Hope this helps :)

MatroZZZ [7]

Answer: 15 inches is the height of Keisha's fish tank.

Step-by-step explanation: Basically, multiply your length x width, which is 12 x 10. 12 x 10 = 120.

Next, divide 1800 by 120.

1800 divided by 120 is 15.

So, 15 inches is the height of the fish tank.

The perimeter of a rectangular garden is 346. if the width of the garden is 79 feet, what is its length?

Nostrana [21]

Perimeter = L + L + W + W
346 = L + L + 79 + 79
346 = L + L + 158
346 - 158 = L + L 158 -158
188 = L + L
So im gonna square root 188
188 ( square rooted) = 13.7113092.....
Im gonna round it so the lengths gonna be
≈ 13.7
