PLEASE HELP QUICK I DON'T KNOW HOW TO DO

Answer 1

Answer:

1. 2

2. 30

Step-by-step explanation:

1. The weird circle looking thing essentially means you're putting p(x) inside of q(x). This means you take the x in q(x) and replacing with the entire p(x)

so q(x) = -3x - 4

(q °p)(x) = -3 (-2x+4) -4  sorry I can't find the actual circle thing symbol

now distribute to get the simplified equation:

= 6x -12 -4

= 6x - 16

because you're doing (q - p )(3), you would plug 3 for x into the new equation

6(3) - 16 = 2

and thats you're answer for the first one

for the second one its the other way around, so you're putting all of q(x) into p(x)

take p(x) : -2x+4

and now replace the x with the entire q(x)

so (p - q)(x) = -2 (-3x-4) +4

simplify: = 6x+8+4 = 6x+12

so now since we're doing (p-q)(3), we need to plug in 3 for x in the new equation

= 6(3)+12 = 30

lmk if those were wrong or if my explanation was unclear, there's another way I can explain it even though its the same process :)

Answer:

37

Step-by-step explanation:

20 + 13 = 33

so 70 - 33 = 37 so the answer is 37

Answer+explanation

so subtract the diffference of 20 and 13 from 70

so first we find the difference and then subtract that from 70

use parenthases so

difference of 20 and 13 is equal to (20-13)

subtract that from 70

70-(20-13)

so you would do the pemdas and get 7 for the inside parethasees then do

70-7=63
