Answer:
33/5 or 6.6
Step-by-step explanation:
Well the most 5r can be is 33, since it has the underline under it, so it's less than or equal to.
So set 5r equal to 33
5r = 33
Divide both sides by 33
r = 33/5
You can leave it in this form or convert it to a decimal which is 6.6
Answer:
x(2x + 3) + (x - 3) (x - 4) = 3x²- 4x + 12
Step-by-step explanation:
<em>Expand:</em>
x(2x + 3): 2x² + 3x
2x² + 3x + (x - 3) (x - 4)
<em>Expand</em>:
(x - 3) (x - 4): x²- 7x + 12
2x² + 3x + x²- 7x + 12
<em>Simplify:</em>
2x² + 3x + x² - 7x + 12: 3x² - 4x + 12
= 3x² - 4x +12
