The area of the region = area of the two rectangles = 64 units².
<h3>How to Find the Area of Rectangles?</h3>
A rectangle has a length and a width, and its area can be calculated using the formula below:
area of rectangle = (length)(width).
The region shown is composed of two rectangles. To find the area of the region, calculate the area of each of the rectangles in the image given.
Area of rectangle 1 = (length)(width)
Length = 12 units
Width = 4 units
Area of rectangle 1 = (12)(4)
Area of rectangle 1 = 48 units²
Area of rectangle 2 = (length)(width)
Length = 4 units
Width = 4 units
Area of rectangle 2 = (4)(4)
Area of rectangle 2 = 16 units²
The area of the region = area of the two rectangles = 48 + 16 = 64 units²

Answer:
The value of X<em> </em>is 6.
Step-by-step explanation:
5 + 3 + 7 + 9 = 24
30 - 24 = 6
X = 6
The difference is 6.
So,
We'll just use A to represent both Jan and Mya's miles, since they ran the same number.
We have the equations:
1. Jan (J) = Mya (M)
2. Sara (S) = M - 8
3. 2A + S = 64
J = M
S = M - 8
We'll just use A to represent both J and M.
S = M - 8
We'll use Elimination by Substitution.
2A + A - 8 = 64
Collect Like Terms
3A - 8 = 64
Add 8 to both sides
3A = 72
Divide both sides by 3
A = 24
Since
A = J
and
A = M
and
J = M
then
J = 24
M = 24
Substitute
S = 24 - 8
S = 16
Check
24 + 24 + 16 = 64
64 = 64 This checks.
So,
J = 24
M = 24
S = 16
Answer:
Since the roots are 3, -4 then we must put
-3, 4 into this equation,
(x +a) * (x +b) = 0
(x -3) * (x +4) = 0 then multiplying
x^2 +x -12
