Answer:
C. AB = 5.8 cm
Step-by-step explanation:
In trapezoid ABCD, EF is the Midsegment.
.:. EF = {(AB+CD)
.:: 9.2 = {(AB + 12.6)
:: 9.2 x 2 = AB + 12.6
.. 18.4 = AB + 12.6
.. 18.4-12.6 = AB
:: AB = 5.8 cm
I don’t really know what it is but you can cross out A, B, and F for sure.
Answer: 13
Step-by-step explanation:
I used Pythagorean theorem to solve this problem. As DC and AD is 12 and 5, you would do 12²+5²= c². 12²= 144 and 5²= 25. 144+25= 169. It doesn't end there. Do the square root of 169 ---> √169=13.
Answer:
b = 7
Step-by-step explanation:
6 b + 6 = 48
Subtract 6 from each side
6b+6-6 = 48 -6
6b = 42
Divide each side by 6
6b/6 = 42/6
b = 7
Answer:
30x - 18
Step-by-step explanation:
6(5x - 3)
<em>Distribute the 6 to both monomials.</em>
6 * 5x = 30x
6 * -3 = -18
<em>Combine both final monomials.</em>
30x - 18
