Write the quadric equation in standard form and then choose the value of "b" (2x-1) (x+5)=0

2x² + 9x - 5 = 0

b = 9

Step-by-step explanation:

(2x - 1) (x + 5) = 0

Expand

2x² + 10x - x - 5 = 0

Simplify

2x² + 9x - 5 = 0

b = 9

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )

according to this law, when unemployment goes up by 1%, gdp drops by 2%. in the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the gdp drops by 6%. thus the effect is a drop in gdp by 6%.
