zysi [14]

Answer:

B. (x+3)(5x+2)

Step-by-step explanation:

The given quadratic trinomial is;

5x^2+17x+6

Comparing this to ax^2+bx+c, we have a=5,b=17,c=6.

ac=5\times6=30

Two factors of 30 that add up to 17 is 15  and 2.

We split the middle term to obtain;

5x^2+15x+2x+6

We factor by grouping;

5x(x+3)+2(x+3)

Factor further

(x+3)(5x+2)

The correct answer is B.

Pia bought a pair of shoes on sale for 30% off. If pia paid $63 for the pair of shoes, what was the original price?
cluponka [151]
So if she got them at 30% off that means 

$63 = 70% 
divide both sides by 70 to get 1%
$0.90 = 1%
multiply by 100 to get full price 
$90 = 100%

original price was $90
