(t point) a rectangular garden is 20 ft longer than it is wide. its area is 7125 . what are its dimensions?
is with equals
and its length equals

feet

feet

Step-by-step explanation:

Let x be the width of a rectangle

Let l be the length of a rectangle

Let A be the area of rectangle

Given.

The garden is 20 feet longer than wide

therefore

Area of rectangle is

We know that area of rectangle is

---------------------(1)

put all known values in equation 1

Find roots of equation by this formula

where

or

check both value in equation 1

So, the is satisfy the equation 1.

So The length of rectangle = = = feet

And width is 75 feet

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
