Answer:
length=10
width=2
Step-by-step explanation:
let w = x
p = l + w
length = 3x + 4
24= 2(3x +4) + 2x
24= 6x + 8 + 2x (combine like terms)
24= 8x + 8 (then subtract each side by 8)
16 = 8x (then divide each side by 8)
2=x
Now plug in 2 for x.
length= 3x+4
3(2)+4
6+4=10
so length equals 10
width equals x, so the width would be 2

Step-by-step explanation:
100- 51 = 49
Answer:
x ≈ 61.3
Step-by-step explanation:
Using the Sine rule, that is
=
( cross- multiply )
5.8 × sinx = 6 × sin58° ( divide both sides by 5.8 )
sin x =
≈ 0.87729, thus
x =
(0.87729) ≈ 61.3
Answer:
Parking costs $2 per hour for the first hour only.
10 degrees is in a 90 degree angle
90-10 =80
use sin
sin(80)=9/x
get x alone
x=9/sin(80)
