positive times positive = positive

positive times negative = negative

negative times positive = negative

negative times negative = positive

$(-\frac{1}{3})(-\frac{1}{3})= \frac{1}{9}$

Negative and negative is positive , so product is positive

$(-\frac{1}{3})(\frac{1}{3})= -\frac{1}{9}$

Negative and positive is negative , so product is negative

$(\frac{1}{3})(-\frac{1}{3})= -\frac{1}{9}$

positive and negative is negative , so product is negative

$(\frac{1}{3})(\frac{1}{3})= \frac{1}{9}$

positive and positive is positive , so product is positive

4. what is the value of x?

Eva8 [605]

Answer:

4. 21

5.120

Step-by-step explanation:

(the answer for #4

I added 5x+15 and 3x-3

and got

8x+12

and because we needed to find the value of x, l did this

8x+12=180

because interior consecutive angles equal 180

and I got 21

(answer for 5)

I then plugged 21 into 5x+15 because angle 1 is equal to it

5(21)+15

I got 120
