The length of a rectangle is 7 inches longer than it's width. The area of the rectangle is 260 square inches. What is the length
bulgar [2K]

Answer:

The width cannot be negative, so w = 9, l = 16.

Step-by-step explanation:

w = the width

l = w +7

A = l · w

A= w ( w + 7 )

144 = w2 + 7w

0 = w2 + 7w - 144

0 = ( w - 9 )( w + 16 )

The width cannot be negative, so w = 9, l = 16.

3/9=21/k what is the strategy for solving it
Vinvika [58]

Answer: k = 63

Step-by-step explanation: You need to multiply the left side by its reciprocal to move the numbers to the right. You also need to multiply by k on the right side to get it alone on the left. This will result in

(9/3)(3/9) = (21/k)(9/3) simplified

1 = 189/3k • k    then multiply by k

k = 189/3 simplify

k = 63

BaLLatris [955]

Answer:

10,000 square feet is the maximum size for a building on this slot.

Step-by-step explanation:

A city lot measures 100 feet x 250 feet. The city zoning ordinance specifies that maximum lot coverage is 40%of the lot.

First we find the total area of city = 100 x 250

Area = 25,000 square feet

Maximum coverage area is 40% of city area

Maximum size of for building on this lot = 40% of 25,000

Now we calculate 40% of 25,000

Maximum size for building = 0.40 x 25000 = 10,000 square feet

Thus, 10,000 square feet is the maximum size for a building on this slot.
