Answer:
x = 16.49
Step-by-step explanation:
By Pythagorean Formula
8.34² + 14.22² = x²
x² = 69.556 + 202.208
x² = 271.764.
x = √271.764
x = 16.4852
x = 16.49 (rounded to 2 dec. pl)
Mutiply the bracket by -2
(-2)(2y)=-4y
(-2)(-3)= 6
4y^3-4y+6+y
4y^3-4y+y+6 ( combine like terms)
4y^ 3-3y+6
Answer: 4y^ 3-3y+6
$26.82
9 * 2.98 = 26.82
pls mark brainliest, thanks :)
