Answer:
The correct answer is C) 10z(x − 2y)
Step-by-step explanation:
To find this, we look for the greatest common factor of those two numbers. Each can be divided by 10 and each have a z. So we divide each term by 10z and put that on the outside of the parenthesis.
So in 10 days the grasshopper (x) is doubled (2x)
20 days it is 2(2x) or 4x
30 days it is 2(4x) or 8x
in 35 days it is 1/2 of 10 so 1/2 times 2 times 8x=8x
it increased by a factor of 8
7-3x=4(2+x)<--Distribute
7-3x=8+4x
-7...... -7

-3x=1+4x
-4x ....-4x
