8 goes into 72 and 8
72÷8=9
8÷8=1
Answer:
Step-by-step explanation:
Given:
Since R is the midpoint of the line, we can set XR equal to RY and solve for x.
Now we know what x is. We can plug in x to RY and XR and then add it all together to find XY. Let's find XR:
Let's find RY now:
Since we know that:
We can plug in our answers:

Answer:
70x³ - 73x² - 155x + 168
Step-by-step explanation:
Given
(5x - 7)(2x + 3)(7x - 8) ← expand the first pair of factors using FOIL
= (10x² + x - 21)(7x - 8)
Each term in the second factor is multiplied by each term in the first factor, that is
10x² (7x - 8) + x(7x - 8) - 21(7x - 8) ← distribute the 3 parenthesis
= 70x³ - 80x² + 7x² - 8x - 147x + 168 ← collect like terms
= 70x³ - 73x² - 155x + 168
