Mischa wrote the quadratic equation 0=-x2+4x-7 in standard form. If a = -1, what is the value of c in her equation?

c=-7

d 192

step-by-step explanation:

we find our area to find area we multiply thoses numbers to get our answer so our area is 192

answer: 3.26019516

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%

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x
