3(7x+ 1) = 21
21x + 3 = 21
21x = 18
x = 6/7

hope this helps!

First, you would simplify both sides of the equal signs, to do this, you would use the distributive property.
21x + 3 = 21

Then, you would subtract 3 from both sides.
21x = 18

Your final step would be to isolate the x, divide both sides by 21.

Your answer would be x = 6/7

I hope this helps!

Answer:

G(x+2) = 7x^2 + 33x + 30

Step-by-step explanation:

So in the G(x) function, to find G(x+2), we just simply plug in the value of x+2 into the function and the result is what is wanted. SO:

G(x+2) = 7(x+2)^2 + 5(x+2) -8 , which is 7x^2 +33x +30 after SIMP - lifying (see what I did there ;)

Hope i helped, please make this brainly. :)

Since this is a triangle all the angles within the triangle add up to 180 degrees so....
82+(9x+2)+(7x)=180
82+2+16x=180
16x+84=180
16x=96
X=6
If we plug in X to angle(9x+2) and angle (7x) we will get 56 and 42. We can get angle 2 by subtracting 180-42 which is 138
FINAL ANSWER: 138 degrees
