Answer:

1 hour later , 21 pages read

Step-by-step explanation:

x hour later they will read the same number of pages

Tori: 16 + 5x

cora: 13 + 8x

16 + 5x = 13 + 8x

minus 5x each sides: 16 = 13 + 3x

minus 13 each sides: 3 = 3x

divide 3 each sides: x = 1

1 hour later both of them will read 16 + 5 x 1 = 21 pages

check cora: 13 + 8 x 1 = 21

Combine like terms, -17-10=-27
-27+2=-25
-10x-10x = -20x

Which expression can be used to find the sumn of the polynomials? (9-3x^2)+(-8x^2+4x+5)
larisa86 [58]

For this case we have:

Polynomial 1: P (x) = 9-3x ^ 2

Polynomial 2: Q (x) = - 8x ^ 2 + 4x + 5

Sorting the polynomials:

Polynomial 1: P (x) = - 3x ^ 2 + 9

Polynomial 2: Q (x) = - 8x ^ 2 + 4x + 5

Adding term to term (similar) we have:

P (x) + Q (x) = (- 3-8) x ^ 2 + (0 + 4) x + (9 + 5)\\P (x) + Q (x) = - 11x ^ 2 + 4x + 14

Answer:

A (x) = P (x) + Q (x) = - 11x ^ 2 + 4x + 14

Daily

So 25.68%, compounded monthly
