Answer:
Width: 15 cm
Area: 150 cm squared
Step-by-step explanation:
I did 10 + 10 to get the total of the two sides of the rectangle.
I subtracted 20 from 50 to get what the two widths are supposed to add up to.
The answer was 30 so I divided 30 by 2 to get what one width equals.
The width equals 15.
To get the area of a rectangle you have to multiply the length by the width which would be 150 cm squared.
2/3x - 14/3 = -2
3(2/3x - 14/3) = -2(3)
2x - 14 = -6
2x = -6 + 14
2x = 8
x = 8/2
x= 4
hope this helps :)
