Answer:
side lengths are 6, 12, 12, 9, 9
Step-by-step explanation:
The perimeter is the sum of the lengths of the sides:
x + 2x + 2x + (x+3) + (x+3) = 48
7x +6 = 48 . . . . collect terms
7x = 42 . . . . . . .subtract 6
x = 6 . . . . . . . . . divide by 7
Substitute this value into the expressions for the side lengths:
x = 6
2x = 12
x+3 = 9
The side lengths are 6, 12, 12, 9, 9.

Answer:
B. x ≤ 5
Step-by-step explanation:
This is an inequality problem. It can be solved by examining the arrow and the point it closes on. If the arrow is going left, then all values of x are going to be <u>less than</u> the point it closes on. If the arrow is going right, then all values of x are going to be <u>greater than</u> the point it closes on.
If the circle on the point the arrow is closed/shaded in, then that value will be included in the values of x, giving the inequality either a ≤ or ≥ sign depending on which way the arrow is pointing. If the circle on the point the arrow is open, then that value will not be included in the values of x. The sign will be either < or >.
---------------------------------------------------------------------------
For this problem, the arrow is going to the left of 5, which means all values of x are going to be less than 5. Because the circle is closed, that means that number 5 is included, or x can be equal to 5. If the circle was open, it wouldn't be included. So, the inequality is x ≤ 5.

Sinα=h/L where h=height, L=string length...
h=Lsinα so
h(25°)=50sin25≈21.1ft
h(45°)=50sin45≈35.4ft
