Mrs. Bell wrote the expanded form of a number, as shown.

5\times 100+4\times 10+6\times 1+2\times \left(\frac{1}{10}\right)+8\times \left(\frac{1}{1000}\right)5×100+4× 10+6×1+2×(
10
1

)+8×(
1000
1

)



What is the number written in standard form?



Enter your answer in the box.

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

step by step explanation: when u removing the parentheses and combined them that would be : x+3y-x-y=2y

y=-2x+1500

step-by-step explanation:

+1500
