Subtract the following polynomials, then place the answer in the proper location on the grid. write the answer in descending powers of a.

subtract: 11a2 + 42a - 6 from 14a 2 - 24a + 7.

answer:

625 people attended at least one play.

step-by-step explanation:

in the given question number of people who attended annual play 1 were=457 and number of people who attended annual play 2 = 372

the people who attended both were 104. now we can say number of persons who attended the play 1 only = 457-104 = 357

and number of people who attended play 2 only = 372-104 =268

therefor the people who attended at least one play = 357+268 = 625

so the answer is 625 people.

answer:

the measure of the other two vertical angles is 65°.

step-by-step explanation:

the measure of supplementary angles is 180°. therefore, as two of the vertical angles equate to 115°, their supplements must create a total sum of 180 when combined. 180-115=65
