I need help with #22
maria [59]

Answer:

4 = y \\ 4 = x

Step-by-step explanation:

The isosceles triangle containing the side of <em>y</em><em> </em><em>+</em><em> </em><em>12</em><em> </em>is congruent to <em>3x² - </em><em>32</em><em> </em>[<em>base angles</em> are congruent], and if you look closer, they are also equivalent to all three sides of the equilateral triangle <em>adjacent</em> to the isosceles triangle. So, we will be working with alot gadgets here, if you know what I mean. Anyway, this is how we start out:

5y - 4 = y + 12

-5y - 5y

___________________

-4 = -4y + 12

-12 - 12

____________

-16 = -4y

___ ___

-4 -4

4 = y [Plug this back into both equations to get the value of 16.]

Next, you will set <em>3x² - 32 </em>equal to 16:

16 = 3{x}^{2} - 32

+32 + 32

_________________

48 = 3x²

__ ___

3 3

16 = x²

4 = x [In this case, we want the NON-NEGATIVE root because inputting a -4 for <em>x</em><em> </em>will not give us identical answers.]

I am joyous to assist you anytime.

Jeremy's father drives him to school in rush hour traffic in 20 minutes. One day there is no traffic, so his father can drive hi
nexus9112 [7]
Hello.

Let's call the initial speed 'x'. When driving at that speed, Jeremy's father takes 20 minutes to arrive to the school. When driving 18 mph faster (x + 18), he gets there in 12 minutes. Therefore:

20 - x
12 - x + 18

As they're inversely proportional:

12 - x
20 - x + 18

\frac{12}{20} = \frac{x}{x+18}
12x + 216 = 20x
216 = 8x
x = \frac{216}{8}
x = 27

That means that the initial speed is of 27mph. Since we have the time and the speed, we can find the distance:

Average Speed = Total Distance Travelled / Time Interval

20 minutes = 0.33h

27 = \frac{Distance}{0.33}
Distance = 27.0.33
Distance = 12.21 miles

Hope I helped and good luck.
