Answer:
10+5x
Step-by-step explanation:
7 and 3 are like terms and 7+3=10
-3x and 8x are also like terms and -3x+8x=5x
Therefore you have 10+5x
100 times 100
When you want to multiply 100 by 100, count up all the zeros first.
There are 2 zeros in one 100 and 4 zeros in two 100's.
Since there are 4 zeros, that means 100 • 100 is a 1 followed by 4 zeros.
This means 100 • 100 = 10,000
100 multiplied by 100 is 10,000 (ten thousand)
Hope this helps!
