The owner of an office building is expanding the length and width of a parking lot by the same amount. The lot currently measure

Gnoma [55]

The best and most correct answer among the choices provided by your question is the second choice or letter B "20".

The current area is 120(80)=9600 and he want to expand it by 4400 so that the new area will be 9600+4400=14000

14000=(120+x)(80+x)

14000=9600+200x+x^2

x^2+200x-4400=0

x^2-20x+220x-4400=0

x(x-20)+220(x-20)=0

(x+220)(x-20)=0, since x is an increase it must be greater than zero so

x=20ft

(120+20)(80+20)=14000ft^2

I hope my answer has come to your help. Thank you for posting your question here in Brainly.

How many eggs are needed to make 1 dozen waffles, assuming you have enough of all other ingredients? given: 2 cups flour + 3 egg

malfutka [58]

We have been given that

2 cups flour + 3 eggs + 1 tbs oil → 4 waffles

In order to make 4 waffles we need 3 eggs.

Thus, to make 1 waffle we need 3/4 eggs.

Now, in 1 dozen there are 12 waffles. Hence, to make 12 waffles we need

$\frac{3}{4} \times 12\\
\\
=3 \times 3\\
=9$
