180-70=110 {Angles in a triangle add up to 180 degrees}
7c-7=4c+17
7c-4c=17+7
3c=24
c=24/3=8
Answer:.....
Step-by-step explanation:sorry bro didnt want to troll you but needed points for my answer
So we need to solve:
3ˣ⁻¹ = 9ˣ⁺²
To do this, we need to have the same base for both sides of the equation.
So let's go with the base of 3.
3² = 9
3ˣ⁻¹ = (3²)ˣ⁺²
3ˣ⁻¹ = 3²ˣ⁺⁴
Since the bases are the same now, we need to get rid of them and we would get:
x - 1 = 2x + 4
Subtract both sides by 2x:
-x - 1 = 4
Add 1 to both sides:
-x = 5
Divide both sides by -1:
x = -5
