Add them up: 5 + 300 + 8 = 513 I suspect that you may have a zero missing: either: 50 + 300 + 8 = 358 or: 5 + 300 + 80 = 385 Expanded form is usually written with the biggest number first and the rest in decreasing value, ie 358 = 300 + 50 + 8 385 = 300 + 80 + 5

As a polynomial in standard form, x plus 5x plus 2 is 6x + 2.
200 + 50 + 5 = 255

Standard form is y=mx+by=3x+5 is already in standard form.

As a polynomial in standard form, x plus 5x plus 2 is 6x + 2.
It is: 3.45*10^5
30 + 5 + 210 = 245
200 + 50 + 5 = 255
Writing a number in standard form simply means to express the number in its 'normal' form. Therefore, your example is written in standard form as: 300,000
