the width of a rectangle is 7 meters greater than its length.If the area of the rectangle is 170 square meters, write the quadra

Anika [276]

Answer:

$x^2+7x-170 = 0$

Step-by-step explanation:

To calculate an area of a rectangle, use the formula A=l*w. We know the width is 7m greater than the length. So w = 7 + x. So the area is A= (7+x)*x.

We also know the area is 170. Substitute this value for A and solve.

$170 = (7+x)(x)\\170 = 7x+x^2\\x^2+7x-170 = 0$

You are wrapping boxes for a fund-raiser. You have 80 large boxes. You need 2 and three-fourths feet of ribbon for each large bo

Ratling [72]

Answer:

5 rolls of ribbon are needed

Step-by-step explanation:

To find how much ribbon you'll use, multiply 80 by 2 3/4. To multiply them, convert 2 3/4 into an improper fraction 11/4.

Multiply: 80 * 11/4 = 880/4 = 220

This means you need 220 total feet of ribbon. Since each roll has 50 feet, you'll need 5 rolls or 250 feet to wrap every box.
