Answer:
EF = 7 units
AD = 3 units
BC = 11 units
Step-by-step explanation:
Since it is an isosceles trapezoid and the midsegment is x, the sum of the bases divided by 1/2 is the value of the midsegment, x.
x = 1/2(x-4 + 2x-3)
x = 1/2x - 2 + x - 1 1/2
x = 1 1/2 x - 3.5
-1/2 x = -3.5
x = 7 units
EF = 7 units
AD = 7-4 = 3 units
BC = 2(7) - 3 = 11 units
Pretty sure x is 4 in #9
FG is congruent to ED, and GD and FE are parallel, so that means
16x + 1 = 65
Subtract 1 on both sides you get
16x = 64
Divide by 16 on both sides
x = 4
Answer:
12x+30
Step-by-step explanation:
6(2x+5)
=(6)(2x+5)
=(6)(2x)+(6)(5)
=12x+30
Answer:
88
Step-by-step explanation:
if the decimal is below 5 then round down
12x+10-5x
12x-5x+10 ( combine like terms)
12x-5x= 7x
Answer: 7x+10
