I hope you see the pattern here . When multiplying the exponent (the small number near the 10) determines the number of zeros to the RIGHT . When dividing the number determines how many zeros to the LEFT usually resulting in a decimal. This is called scientific notation.
Hope this helps!:)
Take out the variable to add the numbers because it is the same variable throughout so 6-5+7=8 then add the n^2 o get 8n^2
Here, we need to find the area of a circle.
So, area of a circle = πr²
= 3.14 * (10, 000)²
= 3.14 * 100,000,000
= 314,000,000 ft²
In short, Your Answer would be Option A
Hope this helps!
Answer:
Step-by-step explanation:
Given the expression 4x+2 = 8X-5. To find the value of x, we need to follow the steps;
Sep 1:
Add 5 to both using addition property to move 5 to both sides
4x+2+5= 8x-5+5
4x+7 = 8x
Step 2:
Collect like terms
4x-8x = -7
-4x = -7
Step3:
Divide both sides by -4
-4x-4 = -7/-4
x = 7/4
