Answer:
-8 or -1
Step-by-step explanation:
x*2+9x+8=0
(x+8)(x+1)=0
x+8=0 or x+1=0
x= -8 or x= -1
Phi earned $100.40. It says, "in data", meaning take the 910 and multiply it by .14 c.
Answer: 63.75 = 85h
Solving gives 0.75 hours.
Step-by-step explanation:
we now that speed = distance / time
therefore time will be Distance / speed
Given that distance = 63.75miles
Speed= 6=85miles per hour
Time(h) = 63.75miles/ 85.---- equation 1
But from the options given, the equation that can also be used to find number of hours is
63.75 = 85h
such that making h subject of formula still give us
h= 63.75/85 as in equation 1 above
solving gives that Time ( h) = 0.75 hours .
The perimeter of a rectangle is 10x + 2 which is a polynomial function. Option C is the correct answer.
<h3>
What is a perimeter?</h3>
A perimeter is a closed path that outlines either a two-dimensional shape or a one-dimensional length.
Given that the length is 3x+2 and the width is 2x-1. The perimeter of a rectangle is given below.
A polynomial function is a function that involves only positive integer exponents of a variable in an equation.
Hence we can conclude that the perimeter of a rectangle is 10x + 2 which is a polynomial function. Option C is the correct answer.
