(x - 9)2 Step-by-step explanation:
Answer:
x = 88
Step-by-step explanation:
All angles in a triangle equal 180 degrees. So our equation will be:
x + 48 + (x - 44) = 180
x + 48 + x - 44 = 180
2x + 48 - 44 = 180
2x + 4 = 180
2x = 176
x = 88

Answer:
x=2
Step-by-step explanation:
3(5x+2)=8x+20
Distribute the 3
15x +6 = 8x+20
Subtract 8x from each side
15x-8x +6 = 8x-8x+20
7x+6 = 20
Subtract 6 from each side
7x+6-6=20-6
7x=14
Divide each side by 7
7x/7 = 14/7
x=2
