x + 7 = 2(3x - 4) Remove the brackets
x + 7 = 2*3x - 4*2
x + 7 = 6x - 8 Subtract 7 from both sides.
x + 7 - 7 = 6x - 8 - 7
x = 6x - 15 Subtract 6x from both sides
x - 6x = - 15
-5x = - 15 Divide by -5
-5x/-5 = -15/-5
x = 3
If two angles are supplementary, their sum equals 180 degrees
Answer:
Company B.

Answer:
B. √6900
Step-by-step explanation:
The square length of hypotenuse is equal to sum of square length of two legs let x represent the other leg
130^2 = 100^2 + x^2
16900 = 10000 + x^2 subtract 10000 from both sides
6900 = x^2 find the root for both sides
x = √6900
