6
Step-by-step explanation:
area of 1 rectangle= area of 2 rectangle
x(x+4) = (2x+3)(x-2)
x² + 4x = 2x² - 4x + 3x - 6
x² + 4x = 2x² - x - 6
x² + 4x - 2x² + x + 6 = 0
-x² + 5x + 6 = 0
x² - 5x - 6 = 0
x² - 6x + x - 6 = 0
x(x - 6) + 1(x - 6)=0
(x+1)(x-6)=0
x = 6,-1
Answer:
x = 4
Step-by-step explanation:
Hello!
We can solve for x by expanding the parentheses and isolating x.
<h3>Solve for x</h3>
- 3x - 2(2x - 5) = 2(x + 3)-8
- 3x - 4x + 10 = 2x + 6 - 8
- -x + 10 = 2x - 2
- 10 = 3x - 2
- 12 = 3x
- x = 4
The value of x is 4.
It is impossible if you don't have any tools. You can construct angle 150 by adding together 90 and 60, both of which can be constructed without any special tools (you would need a compass and a ruler).
To construct angle 150.5 you would need a protractor. A protractor is a device that allows you to construct angles and measure them.
