Answer:x=-5 and x=3
Step-by-step explanation:
log(x^2-15)=log(2x)
Cancel log at both sides we get
x^2-15=2x
Collect like terms
x^2-2x-15=0
x^2-3x+5x-15=0
x(x-3)+5(x-3)=0
(x+5)(x-3)=0
x+5=0 x-3=0
x=-5 x=3
Answer:
See below.
Step-by-step explanation:
I'm assuming these questions are about the Midline Theorem (segment AL joins the midpoints of the non-parallel sides.
♦ The midline's length is the average of the lengths of the top and bottom parallel sides.

Use this equation and substitute values given in each problem, then solve for the missing information.
1. AL = x, CE = 9, OR = 5

2. AL = <em>m</em> - 4, CE = 15, OR = 17

3. OR = y + 5, AL = 15, CE = 18

Answer:
18/25, 5/4, 1.3
Step-by-step explanation:
What you need to do is to divide each fraction so that you can change to a number.
18÷25=0.72
5÷4=1.25
L = 14 - 6 = 8
w = 15 - 4 = 11
P of shaded = 2(8+9) = 2 (19) = 38
answer
last one 38ft
