Answer:
x = 20
Step-by-step explanation:
The 2 given angles are alternate interior angles and are congruent, thus
7x - 3 = 6x + 17 ( subtract 6x from both sides )
x - 3 = 17 ( add 3 to both sides )
Answer: x = +4 or -4
x² - 1 = 15
x² = 15 + 1
x² = 16
Therefore, to solve for x we take the square root of both side
√x² = +/-√16
x² = +/-4
so, x = +4 or -4
6,12,18,24,30,36,42,48,54,60,66,72,78,84,90,96,102,108
9,18,27,36,45,54,63,72,81,90,99,108
So the first 6 common multiples of 6 and 9 are:
Answer: 18, 36, 54, 72, 90, 108
