<span>4x + 8 = −2 − 2 + 5x
5x - 4x = 8 + 4
x = 12
There's only one solution, x = 12</span>
Answer:
P = 6 2/3 ft
Step-by-step explanation:
The formula for the perimeter of a rectangle of length L and width W is
P = 2(L + W).
Here the perimeter is P = 2(1 2/3 + 5/6) = 2(5/2 + 5/6)
= 2(15/6 + 5/6) = 2(20/6)
= 40/6 = 20/3
P = 6 2/3 ft
Answer:
Short leg = √3 cm
Step-by-step explanation:
the opposite angle of long leg is 60°
hypotenuse : x
sin 60° = 3/x = √3 / 2
x = (3 x 2) / √3 = 2√3
short leg length (s)
Cos 60° = 1/2 = s / x = s / 2√3
s = √3
answer:
131.88 inches
step-by-step explanation:
- know the formula: 2πr
- now plug in what we have
2πr = circumference
2(21)(3.14)
= 131.88
