1 answer:

4 0

If you would like to write (-3 + √-9)^2 in a standard form a + i * b, you can do this using the following steps:

(-3 + √-9)^2 = (-3)^2 - 2 * 3 * √-9 + (√-9)^2 = 9 - 6 * 3 * i - 9 = 0 - 18 * i = -18 * i

The correct result would be -18 * i.

I’m stuck... any one able to help? X^4 + 5x^3 + 3x/x

Leni [432]

Answer:

$x^3+5x^2+3x$

Step-by-step explanation:

1) divide each term in the numerator by the term in denominator:

(remember when dividing subtract the smaller exponent from larger exponent

for example: $\frac{x^a}{x^b}$ say a is the larger exponent, do $x^a^-^b$

x^4/x=x^3

5x^3/x=5x^2

3x^2/x=3x

x^3+5x^2+3x

hope this helps!

you practice the piano for 30 min. each day. Write and solve an equation to find the total time t you spend practicing the piano

Tom [10]

Lets get all the information we need first.
A week has 7 days, you practice 30 min each day, so in a week you will practice a total time t of 30 min for 7 times, that is:
t = 7day(30 min/day)
t = 210 min
So in a week you will practice a total of 210 minutes.
