Answer:

expression for cookies Anna have 3c- 8

Step-by-step explanation:

Given:

Number of cookie batches Anna baked = 2

Number of cookies in each batch = c

Number of cookies Anna ate = 8

To Find:

An expression representing the number of cookies left with Anna

Solution:

Let the expression representing the number of cookies left with Anna be y

First let us find the total number of cookies Anna baked

She baked 3 batches of cookies and each batch had c cookies in it

So,

Total number of cookies Anna baked = number batches X Number of cookies in each batch

=> $3 \times c$

=> 3c

=>3c-8 cookies

So , y = 3c- 8

Answer:

20.6

Step-by-step explanation:

<u>Coordinates given:</u>

D(-3,2)
E(4,2)
F(4,-3)

<u>Plotted, these points give a right triangle with hypotenuse DF</u>

Distance DE = 4 - (-3) = 7
Distance EF = 2 - (-3) = 5
Distance DF = √(7²+5²) = √84 = 8.6

<u>Perimeter</u>

P = 7 + 5 + 8.6 = 20.6
