The width of a rectangle is 2 units less than the length. The area of the rectangle is 63 units. What is the length, in units, o
Oduvanchick [21]

Answer: Length = 9 units

Step-by-step explanation:

Let L represent the length of the rectangle.

The width of a rectangle is 2 units less than the length. It means that the width of the rectangle is (L - 2) units.

The formula for determining the area of a rectangle is expressed as

Area = length × width

The area of the rectangle is 63 units. It means that

L(L - 2) = 63

L² - 2L = 63

L² - 2L - 63 = 0

L² + 7L - 9L - 63 = 0

L(L + 7) - 9(L + 7) = 0

L - 9 = 0 or L + 7 = 0

L = 9 or L = - 7

Since the length cannot be negative, then

L = 9 units

Width = 9 - 2 = 7 units

N^2-n-42=0 <br> Please help ASAP !!!!
KatRina [158]

Answer:

(n-7) (n+6)

Step-by-step explanation:

1. You need to find two numbers that's product will equal to 42 and it's sum is -1.

2. You could probably figure out it's 7 & 6 by now and now you have to figure out which one is positive or negative since they both can't be positive or negative since the product needs to be negative and if it will come out to -1. It's simple math from -7 + 6 equals -1. So the 7 would be negative in the equation and the 6 would be positive.
