Jeffrey drew a square field.

The length of the square field is 20 m.

Now he increased the length by 5.

So the new length is 20 + 5 = 25 m.

He also decreases the width by 5 m.

Hence the new width shall be 20 - 5 = 15 m.

The formula for the area of the rectangle is

= length × width

= 25 × 15

= 375 m²

The area of the rectangle after increasing the length by 5 m & decreasing the width by 5 is 375 m².

Dr. W Sweet Rides Car Rental charges a flat fee of $24 and an additional $0.35 for every mile the car is driven. Which function
murzikaleks [220]

Answer:

c = 0.35 x + 24

Step-by-step explanation:

First, let's go over the information we have. We know that no matter what, Dr. W Sweet will charge a base fee of $24, and that for each additional mile, he will charge 35¢. Now let's make an equation reflecting this information:

cost = 35¢ (number of miles) + $24 (starting fee)

We can also write this like this:

c = 0.35x + 24

If you want to test this equation, put in a value for the x variable, like so:

Value: 25 miles

c = 0.35(25) + 24 \\ c = 8.75 + 24 \\ c = 32.75

For this situation, the cost will be $32.75. I hope this helps! If you have questions, comment on this response, I should write back reasonably quickly.

BRIA is a rectangle. AN=5. NR=x-3. please solve for x, NR, and BI
Lena [83]

Answer:

x=8

NR=5 units

BI=10 units

Step-by-step explanation:

In  a rectangle BRIA

AN=5 units

NR=x-3

We have to solve for x , NR and BI.

We know that

Diagonals of rectangle bisect to each other.

BI and AR are the diagonals of rectangle BRIA and intersect at point N.

AN=NR

5=x-3

x=5+3=8

x=8

Substitute the value of x

NR=8-3=5

By property of rectangle

BI=AR=AN+NR=5+5=10 unit

BI=10 units
