Answer:

2x³ + x² - 14x - 7

Step-by-step explanation:

The product of f(x) and g(x) is

(2x + 1)(x² - 7)

Each term in the second factor is multiplied by each term in the first factor

2x(x² - 7) + 1 (x² - 7) ← distribute both parenthesis

= 2x³ - 14x + x² - 7

= 2x³ + x² - 14x - 7 ← in standard form

What is the sum of –356.1 + 258.6
xxTIMURxx [149]

Answer:

Step-by-step explanation:

-356.1 + 258.6 = -97.5

Imagine a long timeline with 0 in the middle, on the left we have -356.1 and on the right we have 356.1. Adding numbers makes the timeline move right.

Starting from the left, add (+) 258.6 to the number (moving right along the timeline). As 356 is larger than 258, the scale does not reach 0 yet and therefore the number must be negative.

Using this logic, the answer is 97.5

Which is the measure of the reference angle for 227 degrees ?
Levart [38]

Answer:

  C.  47°

Step-by-step explanation:

The angle between the terminal ray of 227° and the nearest x-axis (the negative x-axis) is ...

  227° -180° = 47°

The reference angle is 47°.

_____

In mathematical terms the reference angle is the minimum of the angle modulo 180° and the supplement of that angle.

  227° modulo 180° = 47°

  180° -47° = 133° . . . . supplement of 47°

  min(47°, 133°) = 47° . . . the reference angle
