3(2x+4y) distributive property review just need an answer like 5c+15

Mathematics
1 answer:
frozen [14]3 years ago
7 0

Answer:

6x + 12y

Step-by-step explanation:

Using distributive property means multiplying the number outside of the parentheses to each individual number within the parentheses:

3 × 2x = 6x

3 × 4y = 12y

Since there is an addition sign within the parentheses, we add these two numbers together. However, they are not like terms so their sum cannot actually be calculated

6x + 12y

A wheel is shaped like a circle with a diameter of 35 cm. To the nearest
zhenek [66]

Answer:

C = 110 cm

Step-by-step explanation:

The circumference is given by

C = pi *d

C = 3.14 * d

C = 3.14 * 35

C =109.9

Rounding

C = 110 cm

One x-intercept for a parabola is at the point (-2,0).
BARSIC [14]
You can find the x intercept by setting y to 0 and factor the equation.

0=2x^3+3x-2
0=(2x-1)(x+2)

We can make this equation =0 if x is -2 and 1/2.

So the x intercepts are (-2,0) and (0.5,0)

Drag the correct graph to the box under the equation it corresponds to.<br><br> HELP YOU GUYS
ra1l [238]

Answer:

<h2>See below</h2>

Step-by-step explanation:

I can't drag and drop the graphs, but I can graph the equations shown. Then, all you will have to do is match the graphs shown the the graph that I will provide.

<h3>EQUATION 1: y = x² - 2</h3>

Graph Properties:

Opens up

Vertex is 0, -2

Axis of symmetry is x = 0

Graph photo shown in file called equation 1 graph

<h3>EQUATION 2: y = 2x²</h3>

Graph Properties:

Opens up

Vertex is 0, 0

Axis of symmetry is x = 0

Graph photo shown in file called equation 2 graph

<h3>EQUATION 3: y = (x - 2)²</h3>

Graph Properties:

Opens up

Vertex is 2, 0

Axis of symmetry is x = 2

Graph photo shown in file called equation 3 graph

I'm always happy to help :)

Let ​ f(x)=x2−16x+71 ​ .what is the vertex form of f(x)?what is the minimum value of f(x)? enter your answers in the boxes.
adell [148]
Your vertex is (8,7)

First find the x intercept
-2/2a

X = 16/2
X = 8

Substitute the value x and solve for y
Youd get 7

Hence
(8,7)
