The answer is the first one.
Explanation:
X^3 stays the same because there are no other cubed numbers in the problem
Next you combine the x^2s
The x^2s are +3x^2 and +2x^2
Since they are both positive, you add them: 3x^2 + 2x^2 = 5x^2
Next you do the x values
-x and +6x, also known as 6x - x = 5x
Lastly, you just add in the -2 and get:
X^3 + 5x^2 + 5x - 2
Eight ten-thousandths = 8*(1/10,000) = 8/10⁴ = 8 x 10⁻⁴.
Thirty-five million = 35*(1,000,000) = 35 x 10⁶
Therefore eight ten-thousandths of thirty-five million is
(8 x 10⁻⁴) * (35 x 10⁶)
= 280 x 10⁶⁻⁴
= 280 x 10²
= (2.8 x 10²) * 10²
= 2.8 x 10⁴
Answer: 2.8 x 10⁴
4000/5 people = 800 hours per person.
5x8 = 40 hours a week per person
40x5 people = 200 hours a week with all 5 people working.
800/200 = 4 weeks
The answer is 4 weeks
To simplify this expression, you have to distribute. Distribution is when you multiply the outside number by the inside ones. For example, if I distributed 2(4 + 6), I would get (2 × 4) + (2 × 6).
So if we distribute your expression, we'd get:
(-3 × -4y) + (-3 × 3) + 7y
Now simplify:
12y + -9 + 7y
Once more, simplify:
19y - 9
The answer is A
The coefficent is 5, since it’s placed before the variable.
