write a polynomial expression that represents the area of a trapezoid with bases of 6x-5 and 4x+7, and a height of x+1. (A=1/2h(b¹ +b²) )

correct answer is b. 27/8

step-by-step explanation:

answer: 12,000

step-by-step explanation: first you ar e supposed to add. then multiply then subtract

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%
