The midpoint is 1. Between A and B, there are a total of 14 marks on the number line. If you start at -6 and move up 7 marks, you will land on 1. The number 1 is in the middle of -6 and 8.
Answer:
None
Step-by-step explanation:
Let , the supplementary angle be x
then,
x + 69 = 180
x = 180 - 69
x= 111 degrees
so the supplementary angle of 69 degrees is 111 degrees
X^3+8
= x^3+2^3
<span>a^3 + b^3 = (a + b)(a^2 – ab + b^2)</span>
so
x^3+8
= x^3+2^3
= (x+2)(x^2-2x+2^2)
= (x+2)(x^2-2x+4)
