1) Multiply the coefficients
2) Add the exponents (base 10 remains)
(8×3)×10^(2-1)
24×10^(1)
x=12
x/16-1-4=1/2
multiply by both sides
x-4=8
move constant to the right side of and change its sign
x=8+4
add the numbers
x=12

Determine the area of K
First, we need to calculate the length of the rectangle J
This gives:
Divide both sides by 22
So, the length of the rectangle J is 20.
Since both shapes are similar, then:
Substitute the known values:
Express as fraction:
Make Length, the subject of formula
The area of K is:
