1.

1=87 corresponding angle.
2=180-87=93

2.

1=78 corresponding angles
2=78 verticle angles

3.

Set it up as (6x - 11) = 37
37 + 11 =48

6x = 48

x = 8

4.

Take 142 and see that it is supplementary to angle 2 so 180-142 = 38

38 is corresponding to the equation 2(x + 9)

So 2(x + 9) =38
Distributive property

2x + 18 = 38
38-18=20

2x =20

x = 10

Angle 2 is equal to 38 from supplementary to 142

I’m pretty positive about 1-3 but 4 maybe not be correct. But most likely these are correct

What is the solution set to the inequality 5(x - 2)(x + 4) > 0?

Butoxors [25]

Answer:

You selected the correct answer: {x | x <<em> </em>-4 or x > 2}

Step-by-step explanation:

5(x - 2)(x + 4) > 0

Use FOIL method to expand (x - 2)(x + 4):

$5(x^{2} + 2x - 8)$ > 0
