The correct answer would be A
Anon25 [30]3 years ago
6 0

Answer:

The answer is A

Step-by-step explanation:

A * 2 = 1/2πr^2 * 2

2A / π = πr^2 / π

\sqrt{\frac{2a}{\pi } }= \sqrt{r^2}

So, the answer is A because r = \sqrt{\frac{2a}{\pi } }

11b-7-3n+8-5b+9n what is the answer
Sergio [31]

Answer:

6 n + 6 b + 1

Step-by-step explanation:

Simplify the following:

11 b - 7 - 3 n + 8 - 5 b + 9 n

Grouping like terms, 11 b - 7 - 3 n + 8 - 5 b + 9 n = (9 n - 3 n) + (11 b - 5 b) + (8 - 7):

(9 n - 3 n) + (11 b - 5 b) + (8 - 7)

9 n - 3 n = 6 n:

6 n + (11 b - 5 b) + (8 - 7)

11 b - 5 b = 6 b:

6 n + 6 b + (8 - 7)

8 - 7 = 1:

Answer: 6 n + 6 b + 1

Which expression results from using the distributive property 2(5 + r)
Vinvika [58]
Using the distributive property we know we distribute by multiplying the outside values to those inside of the parentheses

outside values: 2

inside values: 5 and r

now multiply out inside values by the outside values

2x5 = 10

2xr = 2r

now plug these values back in for the inside values and take away the outside value and the parentheses

so 2(5+r) using the distribution property is 10+2r
