Dang that’s real hard i feel bad
Answer:D
Step-by-step explanation:
(3x^3 - 5x^2 + 4x - 9)-(7x^3 - 8x^2 - 5x + 10)
open brackets
3x^3 - 5x^2 + 4x - 9 - 7x^3 + 8x^2 +5x - 10
Collect like terms
3x^3-7x^3-5x^2+8x^2+4x+5x-9-10
-4x^3+3x^2+9x-19
Answer:
A and C
Step-by-step explanation:
Answer:
option B 5
option D -6
Step-by-step explanation:
Given in the question an inequality
x² > 16
Step 1
Take square root on both sides of inequality
√x² > ±√16
x < -√16 or x > √16
x < -4 or x > 4
Step 2
-4 > x > 4
x = 5 x > 4 accepted
x = -6 x < -4 accepted
Step 3
x = 4 rejected
x = -1 rejected
