I think its number 3 for sure

The answer is 2.

90 would be the monthly service charge because it is being multiplied by a variable and a monthly charge means that a number is being multiplied every number of months (x). 40 would be the one time installation fee because it is only added once (because there's no variable multiplying it repeatedly.) Y is the total because the installation fee and monthly charge are combined to equal some number (y).

Step-by-step explanation:

$\frac{2 + 3i}{4 - 5i}$

$\frac{(2 + 3i)(4 + 5i)}{(4 - 5i)(4 + 5i)}$

$\frac{8 + 10i + 12i + 15 {i}^{2} }{16 - 25 {i}^{2} }$

$\frac{8 + 22i + 15( -1 )}{16 - 25 ( - 1)}$

$\frac{8 - 15 + 22i}{16 + 25}$

$\frac{ - 7 + 22i}{41}$

So, a= -7

b= 22

c= 41

#4 I need help on. Thanks! (?)

To find the area you just find the area of each triangle.

To do this use the formula b×h×.5=A

6×4×.5=A

A=12

Now you just multiply 12 by 4. The reason you multiply by 4 is because you have 4 triangles that make up the rhombus. The area of the rhombus is 48cm²
