x=10.................................
Answer:
8-(5-x)=2x-8 ⇒ common difference
Step-by-step explanation:
5-x,8,2x
to find the arithmetic difference of the progression
8-(5-x)=2x-8 ⇒ common difference
and solve for x
8-5+x=2x-8
3+x=2x-8
x=11
Factor
fg-5g+4f-20
g(f-5)+4(f-5)
now we factor out the (f-5) in both terms
(f-5)(g+4) is the factored out form
D, the answer is the same but in the parenthesis is reversed using the addiction something property
