Answer:

See Explanation

Answer: $\boxed{ {7}^{14}} .50$

Step-by-step explanation:

${7}^{16} + {7}^{14} \\ \\ = {7}^{14} ( {7}^{2} + 1) \\ \\ = {7}^{14} (49 + 1) \\ \\ = {7}^{14}.50$

Since, one factor of ${7}^{16}+ {7}^{14}$ is 50.

Therefore, ${7}^{16}+ {7}^{14}$ is divisible by 50.

Hence proved.

Answer:

circle of radius 10 centered at (-2, 0)

Step-by-step explanation:

The equation is of the form ...

(x -h)^2 +(y -k)^2 = r^2

with (h, k) = (-2, 0) and r=10.

This is the standard form of the equation of a circle with radius r centered at (h, k).
