Answer:
C is the closest.,
Step-by-step explanation:
I am assuming that the 2 trapezoids CBEF and EFDA are similar (they are similar if the 3 horizontal lines are parallel).
Corresponding sides are in the same ratio , so:
3.4 / EF = EF / 7.6
EF^2 = 3.4 * 7.6 = 25.84
EF = 5.08
Answer:
Infinitely many solutions. Each real number is a solution of this equation.
Step-by-step explanation:
-5 + (-5r) + 10 = -5r + 5
5 - 5r = -5r + 5 <em>add 5r to both sides</em>
5 = 5 TRUE
Answer:
x=1.6 and x=13.4
Step-by-step explanation:
First we must bring -3x over to the left side by addin git the both sides
Answer:
10.5
Step-by-step explanation:
X/-3.5=30-33=-3
X= -3*3.5= 10.5
