Formula for Perimeter of Rectangle:
P = 2(L + W)
Plug in 160:
160 = 2(L + W)
L = 4W
<span>So we can plug in '4W' for 'L' in the first equation.</span>
<span>160 = 2(L + W)
160 = 2(4W + W)
Combine like terms:
160 = 2(5W)
160 = 10W
Divide 10 to both sides:
W = 16
Now we can plug this back into any of the two equations to find the length.
L = 4W
L = 4(16)
L = 64
So the width is 16, and the length is 64.</span>
Answer:
39 in.
Step-by-step explanation:
As it's a regular hexagon all sides are congruent.
Therefore
7x + 4 = 8x - 1
4 + 1 = 8x - 7x
x = 5.
So the required length is 7(5) + 4 = 39 in.
Answer:
1/6
Step-by-step explanation:
There are 2 numbers greater than 4 on a die (5 and 6).
A spinner divided into 12 equal sectors numbered 1 through 12 has 6 even numbered sectors.
Therefore, the probability is:
P = (2/6) (6/12)
P = 1/6
Answer:
A
Step-by-step explanation:
2x² - 4x - 30
2(x²) - 2(4x) - 2(15)
2(x² - 4x - 15)
