“What season is it when you are on a trampoline?”


Simplify Answer

(3x³ + 4 – 2x) + (2x² - x + 6) = E. (the answer is below)

(5x² + 15x – 4) – (3x² – 1 + 7x) = G. 3x³ + 2x² – 3

(11 + 3x³) + (4x² – 2) + 3x = I. 3x³ + 2x² – 3x + 10

(x³ – 4x + 7) – (-2x³ + 6x + 1) = M. 3x³ + 9x - 4

(14x² + 8) + (4x – 2) – (12x² – 1) = N. 2x² + 8x + 7

4x – (-4x³ + 11) – (2x + x³) + 7 = P. 3x³ + 2x² + 7

(6x² – 7x + 2) + (15x + 5 – 4x²) = R. 3x³ + 4x² + 3x + 9

(-2x³ + x² + x – 3) + (5x³ + x² – x) = S. 2x² + 4x + 7

(15x² + x³ + 7) – (6x² – 2x³) – 7x² = T. 2x² + 8x – 3

Answer:
E. 3x³ – 10x + 6

G. 3x³ + 2x² – 3

I. 3x³ + 2x² – 3x + 10

M. 3x³ + 9x - 4

N. 2x² + 8x + 7

P. 3x³ + 2x² + 7

R. 3x³ + 4x² + 3x + 9

S. 2x² + 4x + 7

T. 2x² + 8x – 3
Pakisagot na po plssss ng maayos kailangan ko na po ito ngayon
