Volume = Length x Width x Height

105 = 3x(2x - 3) 

105 = 6x² - 9x

6x² - 9x - 105 = 0

2x² - 3x - 35 = 0
<span>
(x - 5)(2x + 7) = 0
</span>
x = 5 0r x = -7/2 (rejected, because it is negative)

Answer: x = 5

The length of a rectangle is twice its width.
Furkat [3]
The perimeter is the sum of all a shapes sides.

so if length is two times the width, you could write it as 2w.

2w + 2w + w + w = 42. Simplified, it's 6w = 42.
Divide both sides by 6, and you get w = 7.

Since the length is 2w, 2 * 7 = 14, so the length is 14

Area of rectangle is length * width, so do 14 * 7 which is 98. Slap on some units and your answer is 98 sq m

WILL MARK BRAINLIEST!!
Snowcat [4.5K]
15/10 = 18-x/x is the ratio of the larger to the smaller triangle

Cross multiply:
15x = 10(18 - x)
15x = 180 - 10x
25x = 180
x = 7.2

Plug back in to check
15/10 = 1.5

18-7.2/7.2 = 10.8/7.2 = 1.5 :)
