Mathematics

Tanya [424]3 years ago
5 0

Answer:

two solutions

Step-by-step explanation:

If you have a discriminant value greater than zero (not zero and not negative), you're gonna have two solutions. For zero discriminant, one solution. For negative discriminant, no solutions at all.

Make sure you remember this. It will save you from solving a quadratic equation which has no solutions.

The length of a rectangular poster is 2 more inches than three times its width. The area of the poster is 33 square inches. Solv
laiz [17]

Answer:

Step-by-step explanation:

Area of the rectangle = 33 inches sq

Area of a rectangle (formula) = l*b

let the width be x

length = 2 inches + 3x = 2+3x

Area of the rectangle = l*b = 2+3x + x

33 inches sq = 2+3x + x

33 in sq = 2+4x

33/2 = 4x

16.5/4 = x

x = 4.125

width= <u>4.125 inches</u>

length = 2+3x = 2+3(4.125) = <u>14.375</u>

<u></u>

(unless your poster is 32 sq inches and you made a mistake, just replace 33 with 32 and solve it)
