C = 9 m the perimeter is all the sides added together you have 9 +8 that is 17 add another 9 and that equals 26 which is the perimeter.<span />
Answer:
I’m pretty sure it’s 10
Step-by-step explanation:
Because the formula is something like baseXhight divided by two. and 2 times sixty is 120 so 120/12=10 that divided by 2 is five so the answer is either 5 or 10

Answer:</h2>

<h2>
Step-by-step explanation:</h2>
We will use the Gaussian elimination method to solve this problem. To do so, let's follow the following steps:
Step 1: Let's multiply first equation by −2. Next, add the result to the second equation. So:

Step 2: Let's multiply first equation by −1. Next, add the result to the third equation. Thus:

Step 3: Let's multiply second equation by −35, Next, add the result to the third equation. Therefore:

Step 4: solve for z, then for y, then for x:


By substituting
into the first equation, we get the
. So:

Answer:
-13.2
Step-by-step explanation:
-8.2-5 essentially means that you just have to add 8.2 and 5. (disregard the signs for a moment) if you add them you get 13.2 as both of these number have a negative sign just add it and here's your answer
100/98=1.02
1.02×56 tosses landing on tails
57.14% of the tosses would land on tails.
Or 57% if rounded to the nearest ones place.
