Because the left side sqrt is multiplied by 3 if it was just added it would be correct because it would cancel out and leave the 3’s. Since it’s multiplied it would change the value
Answer:

Step-by-step explanation:
B. 30 square units :) hopes this helps
Make equation y intercept form so you can know the slope.of that equation (the slope is the number before the x)
.5x-5y=9
-.5x both sides
-5y=-.5x+9
÷-5 both sides
Y=.1x-9/5
Slope is .1 or 1/10
To have a slope of a perpendicular line you flip the fraction and chance signs
The perpendicular lines slope is -10
In order to solve this you could take the two equations and put them in the same format.
The first equation: <span>y = - 5/4x + 2
The second equation: </span>10x + 8y = 16 For this one, you could take the 16 and subtract it, and then take the 8y and subtract it. 10x - 16 = -8y Divide both sides by -8 -10/8x + 2 = y Simplify
-5/4x + 2 = y
Now you can compare the two equations:
Equation 1: <span>y = - 5/4x + 2
</span>Equation 2: y = - 5/4x + 2
You can obviousley see that they are in fact the same.
