Answer:

The equation for the proportional relationship is y = 2.8x. If the relationship between two quantities is a proportional relationship, this relationship can be represented by the graph of a straight line through the origin with a slope equal to the unit rate.

Answer:

$-\frac{6}{37} + \frac{371}{37}i$

Step-by-step explanation:

We need to evaluate $\frac{(5+6i)(5+6i)}{6+i}$

(5+6i)(5+6i) = (25 + 36i² + 60i) = (25 - 36 + 60i) = -11 + 60i

= $\frac{-11+60i}{6+i}$

Now we rationalize the denominator.

Now, multiplying both the numerator and denominator by (6-i)

$\frac{-66 + 11i + 360i - 60i^2}{36 - i^2} = \frac{-66 + 60 + 371i}{37} = \frac{-6 + 371i}{37}$

= $-\frac{6}{37} + \frac{371}{37}i$

Formula used:

(a+b)² = a² + b² + 2ab

i² = -1

I'm not too sure on this can i have some help

Welcome to Brainly. We are here to help!

Similar polygons vary directly with each other. They have the same scale.

Something I notice about the polygons is that both of the sides are decreased by 10.

40-30= 10 and 28-18=10

Try to find the scale.

40/28= 1.42857....

30/18= 1.666666777

I would say these are not similar polygons. They do not share the same scale.

I hope this helps!
