Please help im kinda confused

Answer:

C

Step-by-step explanation:

We can notice the expression is the special product a^2 - b^2, which can be factored into (a + b)(a - b). By correlating the expression with the formula, we can say:

a^2 = 9r^2

-and-

b^2 = 100s^2t^2

Therefore:

a = 3r

-and-

b = 10st

Now we can substitute these values into the factored form, (a + b)(a - b):

(3r + 10st)(3r - 10st)

This is the same as option C, meaning C is the answer.

Answer:

BxA=F

Step-by-step explanation:

Diagonal AC must be 20 feet so that ∠B will be 90°.

According to asked question, buck is creating a horse coral  by designing in such a way that corners will be at 90°.

So according to question we have to make ∠B as 90°.

So quadrilateral ABCD becomes a rectangular.

Therefore ΔABC  will be a right-angle triangle in which we can use Pythagoras theorem to measure the diagonal AC.

The Pythagoras Theorem says that in a right-angle triangle, the square of the hypotenuse is the sum of square of the other two sides of the right-angle triangle.

In the right-angle tringle ΔABC,

AC²=AB²+BC²

⇒ AC²=16²+12²

⇒ AC²=256+144=400

⇒AC=√400

⇒AC=20 feet

Therefore, Diagonal AC must be 20 feet so that ∠B will be 90°.

Please Mark Brainliest, you are an amazing person thank you and your welcome :D

Step-by-step explanation:

$54 / 6 = $9

Answer:

9

Step-by-step explanation:

You can just divide the 54 by 6 to get the single cost, since it gives a constant rate (possibly not, but most likely since it doesn't mention taxes, tips, ect.)

The unit rate is 9 bucks per pizza.

I have no idea why we would use links in the first place.

Answer:

b = -3

a = -0.5.

Step-by-step explanation:

As both right sides are equal to a:

12b + 3 = -2b - 4

12b + 2b = -4 - 3

14b = -7

b = -0.5.

So a = 12(-0.5) + 3 = -6 + 3

= -3.

Answer:

18

Step-by-step explanation:

So what you need to find is the scale factor which is the scale of the difference between two lengths.

So Figure A is smaller than Figure B, as can be easily detected with our eyes.

Figure A has a ratio of 1/2, as 6/12 is equal to 1/2.

Since B is the original, where A is a scaled version, it must also have the same ratio of 1/2, so twice 9 is 18, which is your answer.

You can also use fractions, by making Figure A into 1/2 because 1/2 = 6/12.

Figure B can turn into 9/x.

Since you know they are scaled factors, they have the same ratio since one is scaled larger or smaller than from the original.

Since it must follow the multiplication of 2 for the side length, 9 x 2 gives your answer.

Also SSA is not congruent because we don't know if the unknown side is equal another thing is SSA spelled back word is A## so lets just leave it at that
