A platform at a construction site is lowered from its maximum height to the ground. The function h(x)= -0.75 + 42 models the height of the platform, in feet, after it is lowered for x seconds. PART A: After how many seconds does the platform reach the ground? (Show all work)

understand that i don't know the answers

will someone answer his question

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

step-by-step explanation:

answer: x=3 and y=4

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%
