Step-by-step explanation:
a) 8x + 5x = 13x
b) 9f + 10f - 12f = 7f
hope it helps...
The answer is a space contains at
least four points that do not lie in a same plane or not all in the same plane. An axiom is a statement or
proposition that is observed as being established, accepted, or self-evidently
true. In other words, it is any statement or mathematical statement that functions
as a starting point from which other statements are logically derived. So this
can be found on postulate 1 that states “a line containing at least two points;
a plane contains at least three points not all in one line; and a space
contains at least four points not all in the one plane.”
Answer:
- 20 + 8i
Step-by-step explanation:
Noting that i² = - 1
Given
[(6i + 9) + (4i - 5)] × 2i ← evaluate the terms inside the square bracket
= ( 6i + 9 + 4i - 5 ) × 2i
= (10i + 4) × 2i ← multiply each term in the parenthesis by 2i
= 20i² + 8i
= 20(- 1) + 8i
= - 20 + 8i
Answer:-3
Step-by-step explanation:
First find g(3).
So g(3)= -2(3)+1 so g(3)= -5
now plug this value into f(x).
f(-5)= (-5)3 +4(3) = -15+12 = -3
#9) b^4 - 81 = (b^2)^2 - 9^2 = (b^2+ 9)(b^2- 9)<span>
#5) m^4-1 = (m^2)^2 - 1 = </span>(m^2 + 1)(m^2- 1)<span>
#10) 81x^4-16 = (9x^2)^2 - 4^2
= (9x^2 +4)(9x^2 - 4)
</span>
