Answer:

Two zeros are 17 and -5

Step-by-step explanation:

Given:

f(x) = x² - 12x - 85

Find:

Zeros of the function

Computation:

f(x) = x² - 12x - 85

f(x) = x² - (17 - 5)x - 85

f(x) = x² - 17x + 5x - 85

f(x) = x(x - 17) + 5(x - 17)

f(x) = (x - 17) (x + 5)

So,

x - 17 = 0 , x + 5 = 0

So,

x = 17 , x = -5

Two zeros are 17 and -5

HELP!!!!!!!!!!!!!!!!!!!!!!! :)
Anestetic [448]

Hey there!

The answers are as follows:

7.)

m∠1 = 85

m∠2 = 95

m∠3 = 85

m∠4 = 85

8.)

m∠1 = 60

m∠2 = 120

m∠3 = 60

m∠4 = 120

9.)

they all equal 90

10.) No. Parallel lines do not cross each other, but these, if extended, would cross. You could use a protractor by measuring corresponding angles, and if they aren't equal, they aren't parallel.

Have a terrifcly amazing day!
