Step-by-step explanation:

Solve by the elimination method

x/5 + y = 6/5

x/10 + y/3 = 7/10

x + 5y = 6 |×2| 2x + 10y = 12

3x + 10y = 21 |×1| 3x + 10y = 22

__________ -

-x = -10

x = 10

x + 5y = 6

10 + 5y = 6

5y = 6 - 10

5y = -4

y = -4/5

Solution → (x,y) = (10 , -4/5)

The perimeter of a rectangle is 84. If the length is 2 more than three times the width, what are the dimensions of the rectangle
Marina86 [1]

The perimeter solved shows that the dimensions of the rectangle are 32 and 10.

<h3>How to calculate the perimeter</h3>

Let the width be w

Length = 3w + 2

Perimeter = 2(length + width)

Perimeter = 2(3w + 2) + 2w

6w + 4 + 2w = 84

8w + 4 = 84

8w = 84 - 4

w = 80/8

w = 10

Length = 3w + 2

Length = 3(10) + 2

Length = 32

The dimensions of the rectangle are 32 and 10.

(-4+2i)(7-2i) <br> Anyone know how to do this??
avanturin [10]

Answer:

<h2>-24 + 22i</h2>

Step-by-step explanation:

Use the FOIL method of multiplication of binomials:

(-4+2i)(7-2i) = -28 + 14i + 8i - (-4)i²

Note that i² = -1.  Thus, - (-4)i² = +4, and we then have:

-28 + 22i + 4, or

-24 + 22i
