Answer:

34m of glass

Step-by-step explanation:

(I'm a visual learner so I'll have a picture of my work as well)

okay, you're going to want to separate this into a large rectangle and a triangle.

From there you're going to calculate the area of both.

rectangle formula:

A= L*H

Triangle Formula:

A= (L*H)/2

Then you just plug in the numbers and calculate, getting 18 for the rectangle and 16 for the triangle. 18+16 = 34

You add the two areas together as shown above, and then you have your area for the whole shape!

For f(x) =4x+1 g(x)=x²-5, find (f•g)(x)​
Inessa05 [86]

Answer:

(f · g)(x) = 4x³ + x² - 20x - 5

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Distributive Property

<u>Algebra I</u>

  • Combining Like Terms
  • Expand by FOIL (First Outside Inside Last)

Step-by-step explanation:

<u>Step 1: Define</u>

f(x) = 4x + 1

g(x) = x² - 5

(f · g)(x) is f(x)g(x)

<u>Step 2: Find (f · g)(x)</u>

  1. Substitute:                    (f · g)(x) = (4x + 1)(x² - 5)
  2. Expand [FOIL]:             (f · g)(x) = 4x³ - 20x + x² - 5
  3. Combine like terms:    (f · g)(x) = 4x³ + x² - 20x - 5

What is the point-slope form of a line with slope -4 that contains the point
adoni [48]

Answer:

y-3 = -4(x+2)

Step-by-step explanation:

Point slope form is

y-y1 = m(x-x1)  where m is the slope and (x1,y1) is a point on the line

y-3 = -4(x --2)

y-3 = -4(x+2)

What is 15/6 in mixed number
jenyasd209 [6]
15/6 is an improper fraction.

Lets convert this into a proper fraction.

How many times does 6 go into 15?

6*2 = 12

Only twice, so our whole number is 2.

15-12 = 3

3 is our numerator.

2   3/6  =   2  1/2

Mixed number form:   2   1/2

Final answer: 2  1/2
