Answer:
So, y = x^2 is a quadratic equation, as is y = 3x^2 + x + 1. All of these are polynomial functions of degree 2. Often you will be given the quadratic ...
<span>(4x³-4+7x)-(2x³-x-8) = </span>4x³-4+7x<span> - </span>2x³ + x+8 = (4x³-2x³) + (7x+x) -4+8 =
= 2x³ + 8x +4
(4x³-4+7x)-(2x³-x-8) = 2x³ + 8x +4

Answer:
X = 3
Step-by-step explanation:
3x = -3x + 15
3x +2x = 15
5x = 15
x = 3
if you walk 4 miles in 1 hour that would be 1 mile every quarter of an hour
a quarter of an hour is 15 minutes
so it would take 15 minutes to walk 1 mile
