Problem 7 is choice B, which is the entire number line shaded in but the value -4 has a hole at this location to mean "exclude this point from the solution set". So basically x can be any number but -4.

Problem 8 is choice C. You have a closed circle (or filled in hole) at -1.5 on the number line. Then you shade to the left of the closed circle to indicate the set of values that are smaller than this endpoint. So n can be -1.5 or it can be smaller than -1.5 (something like -2 or -3, etc).

16x² +8-7x-3x2 - 13x

liq [111]

Answer:

$13x^{2}$ -20x+8

Step-by-step explanation:

Step 1: rearrange the equation

16x^2 - 3x^2 - 7x - 13x +8

Step 2: solve the equation

16x^2 - 3x^2 = 13x^2

-7x - 13x = -20x

(the +8 will stay the same)

so when we put it all together it gives us

13x^2 - 20x + 8

I’m not gonna answer the entire thing for you but I’ll give you a Headstart. In problems like Number nine you take where the Second leg is an subtracted by the first leg giving you the degree measure. And problems like 18 through 21 you have to find angle measures with the same markings
