Answer:
Lets take all factors into consideration first
The door is a rectangle and the area of a rectangle is length times width
Let the width be w
Let the length be l
Equation length × breadth = area
(w+48)w = 3024
w^2 + 48w = 3024
w^2 + 48w - 3024 = 0
w^2 + 84w - 36w - 3024 = 0
w(w + 84) -36 ( w + 84) = 0
(w + 84) (w - 36) = 0
w + 84 = 0 AND w - 36 =0
w = -84 and w = 36
Since width cannot be negative, the right answer is 36
How did I get 84 and 36? Well, I had to factorize 3024 and since 84 times 36 is 3024 and 84 minus 36 is 48, I chose them.

<span>y+2>1/2-2 looks a little strange. Is it OK to combine the last 2 terms?
</span><span>y+2> -3/2
Then y > -2 - 3/2, or y > -7/2. y must be greater than -7/2, greater than -3.5.</span>

Answer:
-5x² -4x +8
Step-by-step explanation:
Eliminate parentheses and collect terms.
(-2x² +3) -(3x² +4x -5)
= -2x² +3 -3x² -4x +5
= (-2-3)x² -4x +(3 +5)
= -5x² -4x +8
Step-by-step explanation:
answer: a) both x are 16, it is an equalatrial triangle
b) (mark as the brainliest and i"ll give you the answer
