Step-by-step explanation:
6x = 23² - 17²
6x = (23 + 17)(23 - 17)
6x = 40 * 6
Hence x = 40.
Answer:
The inverse operation is division
6(x²+15)
Answer is first line
-7(x+9) >= 37+3x
Going to solve for x:
-7x - 63 >= 37 + 3x
-7x - 3x >= 37 + 63
-10x >= 100
x <= 100/-10 (notice the change in equality because we divided by negative)
x <= -10
See the image.
