Determine if x - 2 is a factor of p(x) = x^4-3x^2 + 2x - 8, and explain why.

Step-by-step explanation:

x-2=0

x=2

substitute x=2 into the equation

p(x)=x^4-3x^2+2x-8

p(2)=(2)⁴-3(2)²+2(2)-8

=16-3(4)+2(2)-8

=16-12+4-8

=0

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
