(2+3i)2

= 4 + 6i (distributive property)

if solve for i then

4 + 6i =0

subtract 4 to both sides

6i = -4

divide 6 to both sides

i = -4/6

i = -2/3

Answer:

The answer is 5 beecause coefficients are the number when you multiply a number and a variable. For example 5a the coefficient in that term is 5 if you have 48e the coefficient is 48. So the coefficient is the number when you multiply a number times a variable.

2 triangles are shown. The first triangle has side lengths 35, 20, and 20. The second triangle has side lengths x, 44, 44.
Ad libitum [116K]

The value of x is 77 cm which will make the triangles similar by SSS similarity theorem

Given length of the three sides of one triangle are  35 , 20 and 20

and length of the three sides of another triangle are  x, 44,44

We need to find the values of x by using SSS Similarity theorem

We know that triangles are are similar by side - side - side similarity creation and hence the sides are in the same ratio

As both the triangles are isosceles triangles

Therefore ,

x/35 = 44/20=44/20 (Using ratio)

Solving the equation we get

x=44*35/20

x= 77

Hence the value of x is 77cm

Heinrich is a vacuum cleaner salesman. For each vacuum cleaner he sells, he receives $7. If he sells between 30 and 40 vacuum cl
Semmy [17]

Hi! This is just a simple multiplication problem!

So he recieves 7 dollars for each vacuum cleaner therefore we must multiply 7 by the amount he sells.

7*30 =210

7*35=245

7*40 280

That means he will earn somewhere between 210 dollars - 280 dollars

Hope this helped!
