<u>-2x + 1 = 9</u>
Add 2x to each side of the equation:
1 = 2x + 9
Subtract 9 from each side:
-8 = 2x
Divide each side by 2 :
<u>-4 = x</u>
5(2 + 3) = 5(2 + 3)
10 + 15 = 10 + 15
25 = 25 ✔️
It's would be plus haft that number (it's a negative) and the next number would be 0
After 12 years
3500 * 2 = 7000
after 24 years
7000 * 2 = 14000
14000 : 3500 = 4
so the answer is 24 years
The area is the length times the width. Find area of shapes by counting unit squares. Some shapes will require combining partial square units to find area.<span>
For example - </span><span>A rectangle is 5 centimeters long and 4 centimeters wide. What is its area? </span>
Area = Length * width
The length is <span><span>5</span></span> centimeters. The width is <span><span>4</span></span> centimeters. So the area is <span><span>5 times </span>4</span> square centimeters.
= 20 square centimeters
