Answer:
width is 4
height is 20
Step-by-step explanation:
Area=½ width × height
let the width be x
height will be 6x - 4
40 = ½ × x × (6x - 4)
40 = 2/2 × 3x² - 2x
40 = 3x² - 2x
3x² - 2x - 40 = 0
3x² -12x + 10x - 40 = 0
3x(x-4) + 10(x-4) = 0
(3x + 10)(x - 4) = 0
x = -10/3 or 4
dimension cannot be negative
x is 4
6x-4= 6(4) - 4
24 - 4
20
It is important to keep a
close eye on all the information’s that are given in the question. Based on
those given information’s the answer can be easily deduced.
The distance traveled by Linda in 3 hours = 4.8 miles
Then
In 1 hour the distance traveled by Linda = (4.8/3) * 1 miles
= 1.6 miles
So the speed of Linda is 1.6 miles per hour.
I hope the procedure is simple
enough for you to understand. You can always solve similar kind of problems
using this simple procedure.
The polynomial is in standard form if the exponents are arranged in decreasing order.
