How do you do this? please help me

f = 10, g = 4.8 cm

Step-by-step explanation:

Area of ABCE = 60 cm²

Area of ABCD = 48 cm²

So,

Area of ADE = 60-48

=> 12 cm²

Area of ADE =

Where Area = 12 cm², Base = 4 cm

12 =

Height = 12-2

Height = 10 cm

Where Height is AD

So, AD = 10 cm

Also, AD is parallel and equal to BC

So,

f = 10 cm

Now, Finding g

Area of ABCD =

Where Area = 48 cm², Base = 10 cm

48 = 10 * Height

Height = 48/10

Height = 4.8 cm

Whereas, Height is g

So, g = 4.8 cm

2X (twice a number) - 2 (two less) = -X (opposite of same number).
First, isolate the variable, to do this, add X to both sides. This creates 3X - 2 = 0, then add 2 to both sides. This makes 3X = 2, divide this by 3 and you get the X = 2/3.

To check it, 2*2/3 - 2 is -2/3, which means our answer is correct.
