The cost of a New York Yankee baseball cop is $24,00. The local sporting goods store
mark op rate is 25%. What does the store charge for the baseball cap?

30,00                               this is extrz words bc doesnt work well                                              

Step-by-step explanation:

I think you mean a^2 + 16a + 64.

The x-intercepts are the values of a for which the polynomial equals zero.

a^2 + 16a + 64 = (a+8)^2 = 0

a = 8

The x-intercept is 8.
