D- 2x-1
plug in a number for x and you'll see
X6 – 9x3 + 8 = 0
let u = x^3
u^2 - 9u + 8 = 0
(u-8)(u-1) = 0
u = 1,8
back substitute
1 = x^3
8 = x^3
<span>x = 1 , 2</span>
You did the top right but the denominator is 0 so the slope in undefined or 0.
Hope this helps!
Answer:
The answer to your question is Area = 9 3/8
Step-by-step explanation:
Data
length = 3 3/4 cm
width = 2 1/2 cm
Process
1.- Write the equation of the Area of a rectangle
Area = length x width
2.- Convert the values to improper fractions
3 3/4 = (12 + 3)/ 4 = 15/4
2 1/2 = (4 + 1) / 2 = 5/2
3.- Substitution
Area = (15/4)(5/2)
4.- Simplification
Area = 75/8
5.- Convert to a mixed fraction
9
8 75
3
6.- Result
Area = 9 3/8
