x+1=6
x=6-1
x=5
Answer:79 , 80 , 81
Step-by-step explanation:What three consecutive integers have a sum of 240? What three consecutive integers have a sum of 240? Which means that the first number is 79, the second number is 79 + 1 and the third number is 79 + 2. Therefore, three consecutive integers that add up to 240 are 79, 80, and 81.
8y^2 + 12x - 4y^2 + 24x
= 4y^2 + 36x
Answer:

Step-by-step explanation:
First, remember that the maximum degree of an angle totals 360°.
Since we already have 294°, this means that what is left must total
.
Therefore, this means that our two smaller angles must equal 66°. So:

Solve for x. Add on the left:

Subtract 8 from both sides. Therefore, the value of x is:
