Question

can you do it step by step for me

Answer 1

Answer:

= 10

Step-by-step explanation:

$r + (s+1)^{2}$ ÷ $3$

if, r = 7 and s = 2

SO..

$7 + (2+1)^{2}$ ÷ $3$

..

Add 2 and 1 to get 3.

$7 + \frac{3^{2} }{3}$

Calculate 3 to the power of 2 and get 9.

$7 + \frac{9}{3}$

Divide 9 by 3 to get 3.

7 + 3 = 10

Answer 2

answer: 10
step one: replace r with 7 and a with 2
this will bring you to the equation 7+(2+1)^2 ÷3. (if you don’t know “^2” means squared or to the power of 2)
step 2: do what’s in the parenthesis first following PEMDAS which would be (2+1) and 2+1 is 3. now your equation is 7+3^2 ÷3

step 3: do the exponent, 3^2 is 3*3 which equals 9 so the new equation is 7+9 ÷3

step 4: now you have to do division, 9 ÷3 = 3 so our new equation is 7+3

step 5: addition is last and we have to do 7+3 which is 10 so your answer is 10!


hope this was a good explanation!
