So we can call the width of the rectangle x.
So then the length would be 4x.
The perimeter would then be 10x.
Since the perimeter is 70, we can say 70 = 10x.
And then simplify that to 7 = x.
So the length of a rectangle would be 28 cm, and the width would be 7.
So to find the area, just multiply length by width.
28*7 = 196 square cm
So the rectangle's area is 196 square cm.
I hope I helped!
Answer:
X = -3
Step-by-step explanation:
-5 and -8 are like terms, so you can add 5 to the other side. This leaves you with x = -3
The area of the composite shape is 203ft
Answer:
<h3>Each of the given pairs is not a solution to the given equation.</h3>
Step-by-step explanation:
Put the x and y values in the equation 4y = -7x + 5 and check the equality of the left and right side of the equation.
A. x = -5 and y = 0
L = 4(0) = 0
R = -7(-5) + 5 = 35 + 5 = 40
L ≠ R
B. x = -3 and y = 4
L = 4(4) = 16
R = -7(-3) + 5 = 21 + 5 = 26
L ≠ R
C. x = 1 and y = 3
L = 4(3) = 12
R = -7(1) + 5 = -7 + 5 = -2
L ≠ R
D. x = 2 and y = -2
L = 4(-2) = -8
R = -7(2) + 5 = -14 + 5 = -9
Answer:
Sixed sided die. All but one of the sides are not 3, so that's five sides.
