<u>Congruent
</u>
These are angles, segment, triangles etc. that have exactly the same measures.
Step-by-step explanation:
1. 2x - x + 7 = x +3 + 4
Collecting like terms;
2x - x - x = 3 + 4 - 7
2x = 0
x = 0
2. -2(x + 1) = -2x + 5
Expanding the bracket;
- 2x - 2= - 2x + 5
Collecting like terms;
- 2x + 2x = 5 + 2
0 = 7
It has no solution
3. 4x + 2x + 2 = 3x - 7
Collecting like terms;
4x + 2x + 3x = - 7 -2
9x = -9
x = -1
4. 4(2x + 1) = 5x + 3x + 9
Expanding the bracket
8x + 4 = 5x + 3x + 9
Collecting like terms
8x - 5x - 3x = 9 - 4
0 = 5
It has no solution
5. X + 2x + 7 = 3x - 7
Collecting like terms
x + 2x - 3x = - 7 - 7
0 = - 14
It has no solution
Answer:
2
Step-by-step explanation:
1.67 is closest to 2
Answer:
113.04 (i used 3.14 for pi)
Step-by-step explanation:
area of circle formula = pi r^2
radius = 6
6^2 = 36
3.14 x 36 = 113.04
i don't really know the answer to that but if you stick to it you will increase you're knowledge. good luck!
