An equilateral triangle has a perimeter of 15x3 +33x5 feet. What is the length of each side?
x3 feet
O 5+ 11x2 feet
* 5x2 + 11 feet
5x3 + 11x5 feet

Step-by-step explanation:

Perimeter of equilateral triangle = 15x³ + 33x⁵

side = Perimeter/3

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2
