A. First move all to the left side of the equation(Normal form)
x^3 - 49x= 0
B. Factor out an x, which is the GCF (Factored form)
x(x^2 - 49) = 0
C. Find solutions by making each x piece equal to 0. The first part is just x=0 and the second part is just factoring the difference of squares and then solving.
x=0, x^2 - 49 =0
x=0, x + 7 = 0, x - 7 = 0
Therefore, the answers for Part C are:
x = 0, x = -7, x = 7
you need a number other than 0 on the left side of the decimal point
so 0.33*10-15 is not in scientific notation
58.7266666667
That would be the answer. Hope this helps!
To find out what 2 miles minus 3,333 yards is, first what you have to do is convert one unit to the other. I decided to convert 2 miles into yards. What you can do is multiple how ever many yards is one mile by two. So, there are 1,760 yards in 1 mile. 1,760 x 2 is 3,520. So now we have to subtract 3,520- 3,333.
The answer is 187.
8m=d
m+d=153
d=153-m
8m=153-m
9m=153
m=17
8*17=d
