Use the Associative Property of Addition to write an expression equivalent to (n + 2) + 7. Which expression is equivalent to (n
insens350 [35]

Answer:

The correct answer is OB.

Step-by-step explanation:

Let us recall the Associative Property of Addition: given three real numbers a, b and c the following equality holds:

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

Let us remark that the Associative Property of Addition tells us that we can perform the sums in any order.  So,

(n+2)+7 = n+(2+7).

In the other options there was used the Commutative Property of Addition.

Which point is on the circle centered at the origin with a radius of 5 units?
Aleonysh [2.5K]

Answer:

(2,√21)

Step-by-step explanation:

The circle centered at the origin has equation:

{x}^{2}  +  {y}^{2}  = 25

Any point that satisfies this equation lie on this circle.

When x=2, we substitute and solve for y.

{2}^{2}  +  {y}^{2}  = 25 \\ 4 +  {y}^{2}  = 25 \\  {y}^{2}  = 25 - 4 \\ {y}^{2}  = 21

Take square root to get:

y =  \pm \sqrt{21}

Therefore (2,-√21) and (2,√21) are on this circle.

From the options, (2,√21) is the correct answer
