For this case we have the following expression:

3 (x + 6)

We must apply distributive property, which by definition establishes that:

a (b + c) = ab + ac

Then, applying the distributive property to the expression we have:

3 (x + 6) = 3x + 3 * 6 = 3x + 18

So, 3 (x + 6) = 3x + 18

Answer:

3x + 18

Step-by-step explanation:

<h3>Given</h3>
  • Side 1: 3x² - 2x - 1
  • Side 2: 9x + 2x² - 3
  • Perimeter:  5x³ + 4x² - x - 3
<h3>Part A</h3>

Sum of side lengths 1 and 2

  • 3x² - 2x - 1 + 9x + 2x² - 3 =
  • 5x² + 7x - 4
<h3>Part B</h3>

The perimeter is the sum of all three sides.

<u>The length of the third side is</u>

  • P - (side 1 + side 2) =
  • 5x³ + 4x² - x - 3 - (5x² + 7x - 4) =
  • 5x³ + 4x² - x - 3 - 5x² - 7x + 4 =
  • 5x³ - x² - 8x + 1

Part A - addition

Part B - subtraction

Evaluate the function.<br> f(x) = –2x2 – 10.0<br> Find f(-5)<br> Answer:<br> Submit Answer
Wittaler [7]

Answer:

f(-5) = 0

Step-by-step explanation:

Step 1: Define

f(x) = -2x² - 10x

f(-5) is x = -5

Step 2: Substitute and Evaluate

f(-5) = -2(-5)² - 10(-5)

f(-5) = -2(25) + 50

f(-5) = -50 + 50

f(-5) = 0

In the image, point A is the center of the circle. Which two line segments must be equal in length?
alex41 [277]
The answer is C (EF and HI)

This is because both lines pass through the centre A, meaning both are diameters. Hence, they are equal in length.

I think answer is A
Because slope=rise/run
Rise is 3
Run is 2
But it will be negative because of the direction of slope
