Answer:
B
Step-by-step explanation:
Expressing the ratios as fractions, that is
=
( cross- multiply )
a = 3b
=
( cross- multiply )
c = 5b
------------------------------------------
Given
, substitute values from above for a and c
= 
= 
=
← cancel b on numerator/ denominator
=
→ B
Answer:
(x-2) (x^2 -5)
Step-by-step explanation:
x^3 − 2x^2 − 5x + 10
We will factor by grouping
Take and x^2 out of the first two terms and -5 out of the last two terms
x^2 (x-2) -5(x-2)
Now we can factor out (x-2)
(x-2) (x^2 -5)
The answer is 4x+28 it was pretty simple you just had to add up all the sides
