The area of a rectangular room is 238 square feet. The width is 3 feet less than the length. Find the dimensions of the room.

Answers

Answer:

Step-by-step explanation:

L= length

w= width= L-3

A= area= 238 ft^2

LENGTH

Area Formula

A= LW

substitute w value

238= (L)(L- 3)

multiply L by parentheses

238= L^2 - 3L

subtract 238 from both sides

0= L^2 - 3L - 238

factor

0= (L + 14)(L - 17)

set each parentheses equal to 0

0= L + 14

-14= L

OR

0= L - 17

17 ft= L

*Since the measure of a rectangle would not be negative, L= 17 ft

WIDTH

w= L - 3

w= 17 - 3

w= 14 ft

ANSWER: Length= 17 ft; Width= 14 ft

Answer:

Length= 17 ft; Width= 14 ft

Step-by-step explanation:

L= length

w= width= L-3

A= area= 238 ft^2

LENGTH

Area Formula

A= LW

substitute w value

238= (L)(L- 3)

multiply L by parentheses

238= L^2 - 3L

subtract 238 from both sides

0= L^2 - 3L - 238

factor

0= (L + 14)(L - 17)

set each parentheses equal to 0

0= L + 14

-14= L

OR

0= L - 17

17 ft= L

*Since the measure of a rectangle would not be negative, L= 17 ft

WIDTH

w= L - 3

w= 17 - 3

w= 14 ft

ANSWER: Length= 17 ft; Width= 14 ft

Step-by-step explanation:

4x+3y=5;2y=x−4

brainliest please?

Answer:

The answer to the system of equations is x = 2 and y = -1

Step-by-step explanation:

We can substitute the variables and see how they work with the equations.

2 (-1) = (2) - 4

-2 = 2 - 4

-2 = -2

4 (2) + 3 (-1) = 5

8 + (-3) = 5

8 - 3 = 5

5 = 5
