The values of x in the rectangles will be:
a. x = -3
b. x = 1
<h3>How to calculate the value?</h3>
It should be noted that the variables given in the rectangle will be equated. This will be:
3x + 18 = 24 + 5x
Collect like terms
5x - 3x = 18 - 24
2x = -6
x = -6/2 = -3
b. The value of x will be:
-4 + 9x = 5x
Collect like terms
9x - 5x = 4
4x = 4
x = 4/4
x = 1

Answer:
V=1/2 cm
Step-by-step explanation:
V=l×w×h
V=2 cm×1 cm×1/4 cm
V=1/2 cm
1. To get the result we have to find 75% of 16.
75%=0.75
0.75*16=12 - you should shade 12 triangles.
2. Similar situation
25%=0.25
0.25*24=6 - you should shade 6 triangles
