Answer:
129.9 cm^2
Step-by-step explanation:
You can use the Law of Sines to find the hypotenuse. Because it's an equilateral triangle, it's the same value for the base. If you plug in the proper angles, being 90 degrees and 60 degrees because it's an equilateral triangle, the value of the base should be 17.32050808, or 17.32 if we're rounding. If you use the usual formula for finding the area of a triangle, b * h / 2 to get an answer of 129.9 cm^2. Hope this helps and isn't too confusing! There's a bunch of lessons on Khan Academy if you need more help!
This is a bit advanced for middle school, so we might be missing some information.

Step-by-step explanation:
Answer:
The factor form is:
Step-by-step explanation:
Here we have to find the factor of the expression:
So we need to take out the common terms, as we do for finding the greatest common factors.
Now the expression that is given can be re-written as:
Next, we will find the common terms, as follows;
Now we will factorise the expression:
as follows;
So the final factor form is:
Answer:
? = 49
Step-by-step explanation:
To solve this we just need to understand that when A=1, B=7. So when the side for a is 7 that is basically multiplying A by 7 so we have to do the same to the B side. So when the B side is multiplied by 7 it would be 7*7 =49 so the ? is equal to 49 when that similar side is equal to 7.
This is all based on the fact that the two triangles must be similar triangles.
Answer: 156 miles
Step-by-step explanation:
First, divide 936 by 3 that is 312.
Then, do 3 times 2 because they stoped two times everyday that is 6.
Next, divide 936 by 6 that is 156.
Finally, do 312-156 that is 156.
156 miles is the answer
