Answer:
Step-by-step explanation:
A linear equation in "standard form" looks like Ax + By + C = 0, or
Ax + By = D
x + y = -1
: is in standard form: A = 1, B = 1 and D = -1
-3.x = y
: NOT in standard form
x + 4y = 0 is in standard form
y = 5x - 2 NOT in standard form
x = 3 -0.17 NOT
8x – 3y = 20 is in standard form
First, we determine the area of the wall before cutting out the door by multiplying the dimensions given.
area of wall = ( 9 ft)(5.25 ft) = 47.25 ft²
Then, we determine the area of the door by subtracting from the total area the area of the remaining wall.
area of door = 47.25 ft² - 26.25 ft² = 21 ft²
The two whole numbers that can be the sides of the door are 7 ft x 3 ft.
Answer:
Step-by-step explanation:
