Use the remainder theorem to find the remainder for (x ^5 + 32) divided by (x+2) and state whether or not the binomial is a fact
marta [7]

x+2 is a factor of x^5+32 because (by the remainder theorem) the remainder upon dividing x^5+32 by x+2 is (-2)^5+32=0.

There's also the sum of fifth powers formula,

a^5+b^5=(a+b)(a^4-a^3b+a^2b^2-ab^3+b^4)

Please help! (I'll give brainliest to the first right answer.)
a_sh-v [17]

Answer:

1. 2,3; -2, 3

2. Both points share common values, but their absolute values for the x-value vary.

3. 2,3; 2, -3

4. Both points share common values, but their absolute values for the y-value vary.  

Step-by-step explanation:

For 1, the answer is thus:

-On the graph, the original point is 2, 3.

-A reflection over the y-axis changes the x-value, so it would be -2,3.

Similar for the next chart:

-The initial point is 2,3.

-A reflection over the x-axis changes the y-value, so the reflected point would be 2, -3.

The explanation is:

Both points have similar values except with differences in the absolute value.

Hope this helps you.
