B

AB ≈ 4.41

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos25° = = = ( multiply both sides by AB )

AB × cos25° = 4 ( divide both sides by cos25° )

AB = ≈ 4.41 ( to the nearest hundredth )

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)

step-by-step explanation:

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%
