<span>2 times 10 squared to the second power in standard notation
2 x(10^2)^2
=2x10^4
=20000</span>
24% of 225 is 54, so you do 225+54=279 so 279 is the correct answer :)
Well for the first one,
You have to find out if it is at 25 ft at one second, but since you can't you find the next best thing, find 25 feet then see how many seconds it is at.
For the second one you would have to find where they directly meet, I chose 40 and 20
40 April Sales = 20 March Sales
So this means that for every March sale you would have 2 April sales. 40/20 = 2
3x + 6 = 12
First operation was subtraction (subtracting 6 to leave 3x alone)
Second operation was division (Dividing 3 from 3x to isolare x)
3x + 6 = 12
3x + 6 -(6) = 12 - 6
3x = 6
=
3 and 3 cancels out
x = 2
The distributive property "distributes" a number through all numbers/terms in a set of parentheses by multiplication.
EXAMPLES
Equivalent expressions are the first and last steps. The middle step just shows the work.
5(2 + 3x)= (5*2) + (5*3x)= 7 + 15x
4(2x + 4y)= (4*2x) + (4*4y)= 8x + 16y
10(4x + 5)= (10*4x) + (10*5)= 40x + 50
ANSWER:
Only one pair below is needed for your answer.
5(2 + 3x)= 7 + 15x
4(2x + 4y)= 8x + 16y
10(4x + 5)= 40x + 50
Hope this helps! :)
