81
Step-by-step explanation:
subtract 3 from both sides->x^1/4=-3
set both sides to the power of 4-> x=(-3)^4
solve-> x=81
Step-by-step explanation:
5x = 19 - 4
5x = 15
x = 15/ 5
= 3
hope it helps!
Steps to simplify:
(2x + 3)(x - 7)
~Use FOIL to multiply
(2x * x) + (2 * -7) + (3 * x) + (3 * -7)
~Simplify
=2x² - 14x + 3x - 21
~Combine Like Terms
2x² + (-14x + 3x) - 21
~Simplify
2x² - 11x - 21 (Option 2)
Best of Luck!
