Solve ( 9 - r) ( 2 - 3r) using the FOIL method. QUICK PLEASE!

bazaltina [42]

$\huge\text{Hey there!}$

$\textsf{(9 - r)(2 - 3r)}$

$\textsf{= 9(2) + 9(-3r) + 2(-r) + (-r)(-3r)}$

$\mathsf{= 18 - 27r - 2r + 3r^2}$

$\mathsf{= 3r^2 + 18 - 27r - 2r}$

$\boxed{\large\text{COMBINE the LIKE TERMS}}$

$\mathsf{= 3r^2 + 18 + (-27r - 2r)}$

$\mathsf{= 3r^2 + 18 - 29r}$

$\mathsf{= 3r^2 - 29r + 18}$

$\boxed{\large\textsf{Therefore, your answer is: \large\boxed{\mathsf{3r^2 - 29r + 18}}}}\large\checkmark$

8+(2+6)=(8+2)+6 what property justifies that statement

Vladimir [108]

Answer:

Associative Property of Addition

Step-by-step explanation:

According to the Associative Property of Addition, when three real numbers are added, it makes no difference which two are added first.

(a + b) + c = a + (b + c)

Therefore, 8 + (2 + 6) = (8 + 2) + 6 is an example of the Associative Property of Addition.
