Asap mathematic question worth 12 points

1. (d) First F, then D, then C

2. x=16, not extraneous

Step-by-step explanation:

1. Let's solve the given equation and see which steps we need:

Since the X is under a square root, let's raise both sides to their square value.

So we get: 6x + 4 = 64

Next step is to isolate the x factor, so we need to subtract 4 on both sides, to get:

6x = 60

Then to isolate x, we need to divide both sides by 6.

x = 10.

2. Solve for x.  

We'll first begin by isolating the square root on its side alone:

Then we'll raise each side to its square: x + 9 = 25

Isolate x, to get x = 16

Now, is that solution extraneous or not?

Let's enter 16 in the initial equation and find out:

It works, so the solution is not extraneous!

answer: both chords and diameters have two endpoints on a circle. diameters must intersect the center of a circle.

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
