Answer:
C 315
Step-by-step explanation:
(12 + 30) * 15/2 = 315
Maintaining the same width of the compass as AB, draw an arc from point X such that it intersects the afternoon drawn from N in a point
Answer: No solution
Step-by-step explanation:
(10–3)–2=10–(3–)
10−3−2=10−3, this is false so it is not correct, and the answer for the equation is no solution.

Answer:
<h2>|−9|, −|−9| and −|9| </h2>
Step-by-step explanation:
Before we choose all the expression that is equal to -9, <em>we must understand that the modulus of a value can return both its positive and negative value</em>. For example, Modulus of b can either be +b or -b i.e |b| = +b or -b
Hence the following expression are all equal ro -9
a) |−9| is equivalent to -9 because the absolute value of -9 i.e |−9| can return both -9 and 9
b) −|−9| is also equivalent to -9. The modulus of -9 is also equal to 9, hence negating 9 will give us -9. This shows that −|−9| = −|9| = −9
c) −|9| is also equivalent to -9. This has been established in b above.
