Answer:
none.
Step-by-step explanation:
if you did 0.2*0.2 you would ignore the decimal places for now and just multiply the numbers together:
0.2
x 0.2
__________
04
+ 000
____________
040
Then, you would count the how many numbers are behind the decimals in the multiplication, which is two. then from your answer (040) you would count over two decimal places and put the decimal there. so, in this case the answer would be 0.40 or 0.4. furthermore, the decimal place would not move at all because the numbers you are multiplying are both the same decimal places.

Answer:
C . 4
Step-by-step explanation:
step 1 : -3 multiply with inside of the ( 7x-5 )
= -21x + 15
step 2 : then it will be 21x + 15 = 87 + 3x
step 3 : switch between the odds into like this
21x - 3x = 87 - 15
step 4 : subtract it all
18x = 72
step 5 : bring 18 to the other side
x = 72/18
step 6 : to find the ans of x is just calculate them
x = 72 ÷ 18
= 4
Or you can do like these ⬇️
-3 ( 7x - 15 ) = 87 + 3x
21x + 15 = 87 + 3x
21x - 3x = 87 - 15
18x = 72
x = 72/18 or 72÷18
x = 4
