Hi there!
To create an expression that uses the distribution property which can be simplified into 40 + 4x, we can find a factor between 40 and 4:
Since both 40 and 4 is divisible by 4,
40 / 4 = 10
4 / 4 = 1
We can put the 4 on the outside of the parenthesis, and put the quotients inside the parenthesis. And since the expression is in addition, we should include the addition symbol as the operation inside the parenthesis.
4(10 + x)
would be your answer.
Hope this helps!
16/10
All you have to do to get another way to write a fraction is double the original fraction.
For example...
1/2 = 2/4 = 4/8 = 8/16...
All these are half, 8/16 is the same as 1/2.
Hope this helped. Have a great night!
10+5x=7x-4
1. simplify 7x - 5x
10=2x-4
2. add four to both sides
10+4=2x
+ 4 4
14=2x
3. divide 14 to both sides
14=2x
x=7
The answer is c. Because all you need to know is to find the other leg and find the perimeter of the whole thing.
