Answer:

-8i + 12

Step-by-step explanation:

-4i(2 + 3i) = -8i - [tex]12i^{2}[/tex] = -8i - 12 * (-1) = -8i + 12

Answer:

12−8i

Step-by-step explanation:

-(-4 *3+4*2i)

-4*3=12

4*2=8

=12-8i

Answer: Each pair of gloves costs $15 and each pair of hat costs $10.

Step-by-step explanation:

Let x = Cost per pair of gloves

y= Cost per hat.

As per given, we have

[tex]5x+2y=95 \ \ \ \ (i)\\4x+y=70\ \ \ \ \ (ii)[/tex]

Multiply (ii) by 2 , we get

[tex]8x+2y=140\ \ \ \ (iv)[/tex]

Eliminate (i) from (iv), we get

[tex]3x=45\\x=15[/tex]

Put this in (ii), we get

[tex]4(15)+y=70\\60+y=70\\y=10[/tex]

Hence, each pair of gloves costs $15 and each pair of hat costs $10.

Answer:

Answer: No it isn't an equation. Not yet at least.

Step-by-step explanation:

Yes it might well do, but if it does, it needs something on the other side of wherever you put the equal sign.

Answer:

Do you want the perimeter of this shape?

Answer:

Step-by-step explanation:

Let B = the weight of box B

Let 2B = the weight of box A

Let 2B + 30 = the weight of box C

B + 2B + 2B + 30 = 640

5B = 610

B = 122 pounds, weight of box B

2B = 2(122) = 244 pounds, weight of box A

2B + 30 = 2(122) + 30 = 274 pounds, weight of box C

The property justifies Francesca's first step is subtracting 2.

Here,

Original Equation is,

- 2x + 2 = -4

First step is,

-2x = -6

What is the equation?

An equation is made up of expressions that equal each other.

Now,

Original Equation is,

- 2x + 2 = -4

For find the first step;

-2x + 2 -2 = 4 - 2

-2x = -6

Answer:

The answer is

E=(1, 3)

F=(2,4)

Step-by-step explanation:

When E is midpoint of AB

Then

[tex]e = ( \frac{4 + ( - 2)}{2} . \frac{5 + 1}{2} ) \\ = (1.3)[/tex]

By this way we can find F

[tex]f = ( \frac{4 + 0}{2} . \frac{5 + 3}{2} ) \\ = (2.4)[/tex]

ok

1st one x=245°

2nd one x= 250

Step-by-step explanation:

hope its correct

hope u find it helpful

Answer:

x = 245 and x = 20

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 5 , then

sum = 180° × 3 = 540°

Sum the interior angles and equate to 540

25 + 112 + 100 + 58 + x = 540

295 + x = 540 ( subtract 295 from both sides )

x = 245

---------------------------------------------------------------

5x + 2 + 3x + 5 + 8x + 8 + 4x + 15 + 5x + 10 = 540

25x + 40 = 540 ( subtract 40 from both sides )

25x = 500 ( divide both sides by 25 )

x = 20

The solution to the system of equation is (7, 2)

Using the simultaneous equation:

5x + 3y = 41

2x + 3y = 20

using elimination method

Subtract equation 1 from 2 to have:

5x - 2x = 41 - 20

3x = 21

x = 21/3

x = 7

Substitute x = 7 into equation 1 to get y

5x + 3y = 41

5(7) + 3y = 41

35 + 3y = 41

5y = 41 - 35

3y = 6

y = 6/3

y = 2

Hence the solution to the system of equation is (7, 2)

You can buy 10 magazines in $60.

A unit rate means a rate for one of something.

Given that, the cost of 4 magazines is $24.00

For 4 magazine → $24

So, for 1 magazine = 24/4 = $6

So, in $60,

60/6 = 10

Hence, you buy 10 magazines in $60.
