The following is a trigonometric function: f(x) = cos(2x+2)?
What are the values for a, b, c and d? ​

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this

its 60

4 x 12 = 48

3 x 4 = 12

48 + 12 = 60

yeeeet

i believe it's a.

i'm not sure on this one, most likely correct.

2x + 8
