For 1
1st. 5x+20= 5x(x+4)
2st. 4x-6= 2x(2x-3)
Your welcome if u want i can explain :)
Let the second angle be x.
Second angle = x
First angle = 3x - 6
The sum of the two angles is 180°
x + 3x - 6 = 180
4x - 6 = 180
4x = 186
x = 186 ÷ 4 = 46.5°
Second angle = 46.5°
First angle = 3(46.5) - 6 = 133.5°
Answer: The angles are 46.5° and 133.5°

Answer:
t = 
Step-by-step explanation:
First, you need to complete the -3 + 1 and then expand the brackets
-3 + 1 = -2
7t -2 - (-2) = -3(1 - 3t)
Now expant the -3(1 - 3t) bracket
-3 * 1 = -3
-3 * -3t = 9t
7t - 2 - -2 = 9t - 3
The two negatives turn positive:
7t - 2 + 2 = 9t - 3
7t = 9t - 3
Move the -3 over to the oposite side, and also move the +7t over to the +9t, making it a negative:
3 = 9t - 7t
3 = 2t
Divide both sides by 2:
t = 
So the value of t is
