Answer:
A.) = 6
If RE = 12, then RD = 6
B.) = 10
If BR = 10, then BE = 10
C.) = 16
If BD = 8, then BK = 16
D.) = 30*
<m9 = 90*, and <m2 = 60*, so add them and subtract from 180*, you are left with <m1 = 30*
E.) = 60*
If <m2 = 60*, then <m3 = 60*
F.) = 90*
It`s a 90* angle because BK and RE and perpendicular
G.) = 60*
If <m1 = 30*, then multiply by two because it is symmetrical
I would show all my work but you seem to be in a rush. Hope this helps!
Answer:
12
Step-by-step explanation:
This is a difference of perfect squares which is of the form:
(a^2-b^2)
And which always factors to:
(a-b)(a+b)
In this case:
(5x-8)(5x+8)
