1st one is simple factoring (x+20)(x-15), choice 3 2nd one also factoring (5x+1)(x-2), choice 3 3rd one has a b in both terms so factor that out b(a^2-25) now you have a difference of squares b(a+5)(a-5), choice 1 Bonus Answer: i don't know if you want it but ill give it to you anyway sum is 7, square root of 49 is 7, 7^4 is 2401 so answer should be 2401x7=16807 and i tried it it works :)

take (93 + 87 + 82 + 86 + x + (x+4) ) / 6 = 87 and solve it for x. Note that it doesn't matter if you use x+4 or x-4... the results will be the same. If you use x+4, x will represent the lower score, and if you use x-4 the x will give you the higher. Given the choice of + or - to work with, I typically choose +.

Let the scores of Angela in six tests respectively be: 93,87,82,86, x and x-4.So average = [93+87+82+86+x+x-4]/6 = 87 or [93+87+82+86+x+x-4] = 87*6 = 522 or 344 + 2x = 522 or 2x = 178 or x = 89 So Angela scored 89 on fifth test and 85 on sixth test.

the answers are: 1. 3 2. 3 3 .1 (these are numbers for the correct answers - all found by factoring) sum them = 7 now square root 49 = 7 7^4 x 7 = 7^5 = 16807

1. (x+20)(x-15) 20x-15=-300 20-15=5 2.(5x+1)(x-2) -2x5=-10+1=-9 3. b(a^2-25) b(a-5)(a+5) I dont know how to show my work it is just guessing and checking till it works.

5 - 4|2 - 3t| > 21 -4|2 - 3t| > 16 |2 - 3t| < -4 There is no solution because an absolute value cannot be negative.
