Answer:
-220
Step-by-step explanation:
-5 x 1 x 11 x 4
times -5 and 1 = -5
-5 times 11 is -55
-55 times 4 is -220
Sarah scored 82 points on her first test of the year. On the second test,
82%
On the Second Test, She scored 77 points
77%
82
-77
=5
The Percent of Change is 5%
or -5% Because The second test Is lower than her first test
The sum of the area of these three rectangles will be 3x² + 20x.
<h3>What is the area of the rectangle?</h3>
Let L be the length and W be the width of the rectangle.
Then the area of the rectangle will be
Area of the rectangle = L×W square units
The lengths and the widths of the following three rectangles are labeled.
The area of the first rectangle will be
A₁ = x · x
A₁ = x² square units
The area of the second rectangle will be
A₂ = 20 · x
A₂ = 20x
The area of the third rectangle will be
A₃ = 2x · x
A₃ = 2x²
Then the sum of the area of these three rectangles will be
A = A₁ + A₂ + A₃
A = x² + 20x + 2x²
A = 3x² + 20x
Thus, the sum of the area of these three rectangles will be 3x² + 20x.

Hello :
<span>x²- y = 3 ...(1)
x - y = -3 ...(2)
by (2) : y = x+3
subqct in (1) : x²-x-3 = 3
x²-x-6 =0
(x+2)(x-3) = 0
x+2 =0 or x-3 =0
x=-2 or x=3
if x = -2 y = -2+3 = 1
if x=3 y =3+3 = 6
two solutions : ( -2, 1) , (3,6)</span>
Well, it would help if you added a picture of some sorts.
