A(-3, -1); B(2, -1), C(2, 3)

You can read the length of AB and BC.

|AB| = 5

|BC| = 4

Use the Pythagorean theorem:

$|AC|^2=5^2+4^2\\\\|AC|^2=25+16\\\\|AC|^2=41\to|AC|=\sqrt{41}\\\\|AC|\approx6.4$

The perimeter:

$P=|AB|+|BC|+|AC|\\\\P=5+4+6.4=15.4$

-3(8n - 5) - 2n = 8n - 21

BigorU [14]

Answer:

Step-by-step explanation:

First you do the parentheses so the -3 x 8n= -24 and -3 x -5= 15

so it will look like this. -24n+15-2n=8n-21

Now combine like terms the -24n-2n.

-26n+15=8n-21 now subtract 8n now it will look like this

-34n+15=-21 now -15 from -21

-34n=-36

now if you want n by its self divide -34 and -36

It takes 4 3/8 cups of cheese,7/8 cups of olives,and 2 5/8 cups of sausage to make a signature pizza. How much cheese is needed

Crank

$43\frac{3}{4}$ cups of cheese is needed to make 10 pizzas.

Explanation

For making one pizza, amount of cheese needed = $4\frac{3}{8}$ cups = $\frac{35}{8}$ cups.

Now for finding the total amount of cheese needed to make 10 pizzas, we need to multiply $\frac{35}{8}$ cups by 10.

So, $(\frac{35}{8}*10)cups= \frac{350}{8}cups= \frac{175}{4}cups= 43\frac{3}{4} cups$

Thus, $43\frac{3}{4}$ cups of cheese is needed to make 10 pizzas.
