Forgive me if I've read your question wrong but I see
\frac{20-45x^2}{6x^2-x-2}
= \frac{5(4-9x^2)}{6x^2-x-2} =  \frac{5(2-3x)(2+3x)}{6x^2-x-2}
= \frac{5(2-3x)(2+3x)}{(3x+2)(3x-1)} =  \frac{5(2-3x)}{3x-1}

Determine the measure of arc CED. <br><br> A. 180°<br> B. 99°<br> C. 198°<br> D. 81°
Lina20 [59]

Answer:

C

Step-by-step explanation:

An angle whose vertex lies on a circle and whose sides are 2 chords of the circle is one half the measure of the intercepted arc.

arc CED is the intercepted arc, hence

arc CED = 2 × 99° = 198°

PLEASE PLEASE PLEASE HELP! Please explain step by step!! Please please I'll give enough points!

1)
The distance between points A and B is;
d= \sqrt{(x2-x1)^{2} + (y2-y1)^{2} } \\&#10;d= \sqrt{(1-5)^{2} +(12+8)^{2}}\\ &#10;d= \sqrt{(-4)^{2} + (20)^{2}}\\&#10;d=\sqrt{16+400}\\&#10;d=\sqrt{416}\\&#10;d=4\sqrt{26}, 
and if you wanted to you could measure out the legs of that hypotenuse using the slope between A and B, but I'm going to show you the easier way;
Δx = 4
Δy = -20
So from the midpoint, add 4 to the x-value and subract 20 from the y-value.
{(5+4),(-8-20)}
(9,-28) is the endpoint.

2)
Do the same thing as I did above;
d= \sqrt{(x2-x1)^{2} + (y2-y1)^{2} } \\ &#10;d= \sqrt{(5-(-3))^{2} +(5-(-4))^{2}}\\&#10;d=\sqrt{(5+8)^{2}+(5+4)^{2}}\\&#10;d=\sqrt{(13)^{2}+(9)^{2}}\\&#10;d=\sqrt{169+81}\\&#10;d=\sqrt{250}\\&#10;d=5\sqrt{10}
So 5\sqrt{10} is the distance.

Sorry for the delay, life delayed me a ton ,:D

Dale currently has $599 in his savings account. Prior to getting paid, he had $230 in his savings account. How much was Dale’s p
nlexa [21]
Hi!

So really focus on the fact that he started at $230, and then added an amount of money which we'll call x, which made his total equal $599. 

Take the parts I put in bold, and write the equation.
$230 + x = $599

Now we need to find x. 

Whatever we do to the equation, we do it to both sides. 
Our goal is to isolate x on one side. 

Subtract 230 from both sides. 
$230 - $230 + x = $599 - $230
x = $369

The answer is A. $230 + x = $599 x = $369

Hope this helps! :)
