Answer:
Width = 2
Length = 5
Step-by-step explanation:
let A be the area of the rectangle
L be the length of the rectangle
w be the width of the rectangle
<u><em>Formula</em></u>: ‘<u><em>area of a rectangle</em></u>’
A = L × w
…………………………………………………
A = L × w
⇔ 10 = (w + 3) × w
⇔ 10 = w² + 3w
⇔ w² + 3w - 10 = 0
<u><em>Solving the quadratic equation</em></u> w² + 3w - 10 = 0 :
Δ = 3² - 4(1)(-10) = 9 - (-40) = 9 + 40 = 49
then √Δ = 7


-5 is not valid ,because w represents the width
which must be a positive number
Then w = 2
<u><em>Conclusion</em></u>:
Width = 2
Length = 2 + 3 = 5
Answer:
An extraneous solution is a solution obtained through algebraic manipulations that is not a solution to the original equation.
Step-by-step explanation:
I hope this helps you
if 3/8 miles per a hour
7/8 miles ? hour
?.3/8=7/8.1
?=7/3
?=2,3333... hour
This reduces to a simple addition problem.
You walk 1/6 or one sixth of a mile, then 1/3 or one third of a mile.
The result is 1/3 + 1/6.
Using basic properties of fractions, we can substitute 2/6 for 1/3:
2/6 + 1/6 = 3/6.
3/6 is three sixths, which is exactly 1/2.
So in total, you walked 1/2 miles.
