Answer:
2
Explanation: A plane contains at least three non-collinear points. If two points lie in a plane, then the line containing them lies in the plane. If two planes intersect, then their intersection is a line.
Answer:
2x^3 + 15x^2 + 27x + 5
Step-by-step explanation:
2x(x^2 + 5x + 1) + 5(x^2 + 5x + 1)
2x^3 + 10x^2 + 2x + 5x^2 + 25x + 5.....then
add the values with the same variables...
2x^3 + (10x^2 + 5x^2) + (2x + 25x) + 5
; 2x^3 + 15x^2 + 27x + 5

A shorthand method of writing very small and very large numbers is called scientific notation, in which we express numbers in terms of exponents of 10. To write a number in scientific notation, move the decimal point to the right of the first digit in the number. Write the digits as a decimal number between 1 and 10.
