Answer:
m=2
Step-by-step explanation:
(x+1).2
y=2x+2
m=2
Answer:
C
Step-by-step explanation:
The diagram shows the system in equilibrium. Left part consists of 3 circles, 2 triangles and 6 squares. Right part consists of 2 circles, 5 triangles and 3 squares.
If this system is in equilibrium, then the mass of the left part is the same as the mass of the right part.
<u>The mass of the left part:</u>
![3\cdot 3+2\cdot \triangle +6\cdot 2=2\triangle+9+12=2\triangle+21\ grams](https://tex.z-dn.net/?f=3%5Ccdot%203%2B2%5Ccdot%20%5Ctriangle%20%2B6%5Ccdot%202%3D2%5Ctriangle%2B9%2B12%3D2%5Ctriangle%2B21%5C%20grams)
<u>The mass of the right part:</u>
![2\cdot 3+5\cdot \triangle+3\cdot 2=5\triangle +6+6=5\triangle +12\ grams](https://tex.z-dn.net/?f=2%5Ccdot%203%2B5%5Ccdot%20%5Ctriangle%2B3%5Ccdot%202%3D5%5Ctriangle%20%2B6%2B6%3D5%5Ctriangle%20%2B12%5C%20grams)
Hence,
![5\triangle +12=2\triangle +21\\ \\5\triangle -2\triangle =21-12\\ \\3\triangle =9\\ \\\triangle =3\ grams](https://tex.z-dn.net/?f=5%5Ctriangle%20%2B12%3D2%5Ctriangle%20%2B21%5C%5C%20%5C%5C5%5Ctriangle%20-2%5Ctriangle%20%3D21-12%5C%5C%20%5C%5C3%5Ctriangle%20%3D9%5C%5C%20%5C%5C%5Ctriangle%20%3D3%5C%20grams)
What does the triangle look like? If the base angles or two of the side lines are congruent then it is a isosceles triangle. If all the angles are congruent or all the sides, then it is an equilateral triangle. If non of the angles or sides are congruent then it is a scalene triangle
Answer: A and B
Explanation: If you draw the graph out it crosses the points (1,2) and (-1,-2) and those are points A and B
Answer:
Step-by-step explanation:
i dont know the rest but the answer to x is 15 because the formula to that triangle is A^2+B^2=C^2
A=12
B=9
144(12^2) and 81 (9^2) add
225
find square root
15
z=15
