$\huge\text{Hey there!}$

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

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

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

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

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

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

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

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

Nonamiya [84]

Answer: 61

Step-by-step explanation: It's going up by five each time. We can write a function...

f(x)=5x+1

Starting Value: 1

Rate of Change: 5

x=12

f(12)=5(12)+1

5 times 12 is 60

60 + 1= 61

Brian spins a fair spinner numbered 1 - 5 and flips a fair coin.

Greeley [361]

Answer: 0.1

Step-by-step explanation:

If we spin a fair spinner numbered 1 - 5 and flips a fair coin.

Then, the possible outcomes will be :-

$(1,T),(2,T), (3,T), (4,T), (5,T)\\\\(1,H),(2,H), (3,H), (4,H), (5,H)$

i.e. total 10 possible outcomes.

The favorable outcomes = a 2 and a head i.e. only 1 .

Now, the probability of obtaining a 2 and a head will be :_

$\dfrac{\text{Number of favorable outcome}}{\text{Total outcomes}}\\\\=\dfrac{1}{10}=0.1$

Hence, the probability of obtaining a 2 and a head = 0.1
