A rectangle of Length (4x-1) cm and Breadth (2x), has an Area 10 cm² find x

x = 1.25

Step-by-step explanation:

Givens

Area = L * w

L = 4x-1

w = 2x

Area = 10 cm^2

Formula

A = L * w

Area = 2x(4x - 1)

Solution

Area = 2x (4x - 1) = 10           Remove the brackets

2x * 4x - 2x = 10                    Subtract 10 from both sides

8x^2 - 2x - 10 = 0                  Factor

This factors into

(4x - 5)(2x + 2) = 0

4x - 5 = 0

4x  = 5

x = 5/4

x = 1.25

2x + 2 = 0

2x = -2

x = - 1      When talking about area, this is an impossible answer.

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,
