Answer:
x= 1/20
Step-by-step explanation:
-1/2x = -10
multiply by 2x on each side
2x(-1/2x) = -10*2x
-1 = -20x
divide by -20
-1/-20 = -20x/-20
1/20 =x
Answer:
a^3+b^3=(a+b)(a^2-ab+b^2)
Step-by-step explanation:
x^3+27=(x+3)(x^2-3x+9)
The correct answer for the given statement above would be FALSE. If two points of a ray lie in a plane, then not all of the ray lies in the plane because i<span>f two points of a ray lie in a plane, that does not imply that the ray lies in the plane. If A then B, B does not necessarily imply A. This makes the statement incorrect. </span>
The answer is B. 6, 18, 54, 162.
A geometric sequence is a when a group of numbers are multiplied by another number. Each number in answer B is multiplied by 3.
6*3=18
18*3=54
54*3=162
