Step 1 = Distributive Property ( multiplying the 2 by each term in parenthesis)

Step 2 = Addition Property ( adding like terms)

Step 3 = Addition Property (adding 34x to each side)

Step 4 = Division Property. ( dividing both sides by 17)

Write the expression in standard form. five divided by quantity three minus fifteen i.

EleoNora [17]

Standard form is a+bi where a and b are real numbers
remeber that i²=-1

ok

$\frac{5}{3-15i}$
we got to get the i out of the denomenator
remember the differnce of 2 perfect squares where (a-b)(a+b)=a²-b²

so multiply the whole thing by $\frac{3+15i}{3+15i}$
we get
$\frac{5(3+15i)}{3^2-(15i)^2}=\frac{15+75i}{9-225(-1)}=\frac{15+75i}{9+225}=$ $\frac{15+75i}{234}=\frac{15}{234}+\frac{75i}{234}=\frac{15}{234}+\frac{75}{234}i=\frac{5}{78}+\frac{25}{78}i$

in standard form, it is $\frac{5}{78}+\frac{25}{78}i$

Three rock samples have masses of 74.05 grams, 9.72 grams, and 45.49 grams. A scientist estimates the tatal mass of the samples

NeX [460]

The lists he would add would be C because 74.05 rounds to 74, 9.72 rounds to 10 and 45.49 rounds to 45 because it is closer to 45 than 46.

Answer:

There are six important properties of parallelograms to know:

-Opposite sides are congruent (AB = DC).

-Opposite angels are congruent (D = B).

-Consecutive angles are supplementary (A + D = 180°).

-If one angle is right, then all angles are right.

-The diagonals of a parallelogram bisect each other.
