A) 115
B) 133
C) 162
D) 174

58 out of 100 students use browser B.
So we predict 58*300/100=174 out of 300 students to be using browser B.

Jim has a piece of cardboard with length (4x2 − 2x + 1) inches and width (3x2 + 3x − 4) inches. Which statement best explains why the area of the cardboard proves the Closure Property?

A) The length multiplied by the width is equal to the width multiplied by the length.
B) The length multiplied by the width has the same degree as the width multiplied by the length.
C) It is equal to (12x4 + 6x3 − 19x2 + 11x − 4) square inches, which is also a polynomial like the length and width.
D) It is equal to (12x4 + 12x3 − 16x2 − 8x − 4) square inches, which is also a polynomial like the length and width.

math&ing001 · Answer

You'll need to distribute (4x2 − 2x + 1)*(3x2 + 3x − 4). Do you know how to ?

12x^4 + 6x^3 - 19x^2 + 11x - 4?
