-250/-5= 50
So -250 divided by 50 equals -5
The answers 50
Factor 2 from both 2x^2 as well as -32
2x^2/2 = x^2
-32/2 = -16
2(x^2 -16) Is your factored form
Hope this helps
Answer:
? = 14
Step-by-step explanation:
If ∆EFG ~ ∆CBA, we have the proportion
FG/FE = BA/BC . . . . . any pairs of corresponding sides will have the same ratio for similar triangles. (It is convenient to put the unknown in the numerator.)
?/18 = 21/27 . . . . . . filling in the given numbers
Multiplying by 18, we have ...
? = 18·21/27
? = 14
_____
If the triangles are not designated as being similar, the problem is unworkable.
