Answer:
3x^4 + 7x^3 - 5x^2 + 8x - 13
Step-by-step explanation:
(3x^4 + 7x^3 - 9) - (5x^2 - 8x + 4) =
The negative sign to the left of the second set of parentheses changes every sign inside the parentheses.
The first set of parentheses is unnecessary, so we just drop it.
= 3x^4 + 7x^3 - 9 - 5x^2 + 8x - 4
Now we combine like terms.
= 3x^4 + 7x^3 - 5x^2 + 8x - 13

Given a point on the line segment BD, the internal division formula is given by:
Therefore:
Therefore the fraction which compares BC to BD is
Answer:
B.Multiply and C. add
Step-by-step explanation:
In scientific notation the number can be divided and multiplied rather simply by taking the advantage of the number's property and the exponential rules that should be recall.
In scientific notation the multiplication can be done as by multiply the numbers which are not in the power of 10.
And after that we can multiply the power of ten by adding the exponential terms.
Therefore in scientific notation while determining the product of 2 numbers we can multiply the base and add the exponent of the power of ten.
