Answers

Answer 1

Answer:

Explanation below

Step-by-step explanation:

(3+4)= 7

7+2 = 9

-(3-4) (Invisible one)

-3+4 add to the 9

10+2= 12

12-4=8

8×4 =32

Sorry if this seems a bit confusing, but its quite hard to show the process without paper.

Consider this expression.
-3x2- 24x - 36
What expression is equivalent to the given expression?

Answers

Answer:

-3 2 6

Step-by-step explanation:

Consider this expression.

-3x2- 24x - 36

What expression is equivalent to the given expression?

-3 (x + 2)(x+6)

Drop down answer is in bold

The equivalent expression will be : - 3 (x + 2) (x + 6)

We have the following expression -

[tex]-3x^{2}[/tex] - 24x - 36

We have to find out the equivalent expression of above expression.

Expand the following expression - (x + 2)(x + 4).

Above expression can be expanded in the following way -

(x + 2)(x + 4) = x(x + 2) + 4(x + 4) = [tex]x^{2}[/tex] + 2x + 4x + 16 = [tex]x^{2}[/tex] + 2x + 16

According to question -

[tex]-3x^{2}[/tex] - 24x - 36

- 3 ([tex]x^{2}[/tex] + 8x + 12)

-3 ([tex]x^{2}[/tex] + 6x + 2x + 12)

-3 [x(x + 6) + 2(x + 6)]

-3(x + 2)(x + 6)

Hence, the equivalent expression will be : -3(x + 2)(x + 6)

hello I need help with graphing my functions it's y = 2x + 3 but I need to graph it

Answers

The variable x is a placeholder for a number

Let's say we replace x with 0

y = 2x+3

y = 2(0)+3

y = 0+3

y = 3

This means x = 0 and y = 3 pair up together. In short, the point (0,3) is on the line.

--------------

Let's repeat for x = 1

y = 2x+3

y = 2(1)+3 ... replace x with 1

y = 2+3

y = 5

So (1,5) is another point on the line

---------------

We can keep this process going to generate as many points as we want. But to graph a linear equation like this, we only need two points at minimum.

Graph both (0,3) and (1,5). Then draw a straight line through them both. The graph is shown below.

What is the value of the expression below when z = • 3?
622 + 2z + 10

Answers

Answer:

632.6

Step-by-step explanation:

Z = .3 right? It looks weird on my screen

Anyway, if z is .3 than this is how to solve

First you plug in 0.3 where the z would go, making the expression 622 + 2(0.3) + 10. Then you solve! (below)

622 + 2(0.3) + 10.

622 + 0.6 + 10.

622 + 10 + 0.6

632 + 0.6

632.6

GEOMETRY A container company wants to make a
cylindrical cardboard container with a volume of 4752 cubic inches. The formula V = roh represents the volume of a cylinder. In this formula, V represents the volume, represents the radius of the cylinder's base, and h represents the height of the cylinder. Solve for h. What height should the company make the container if the radius of the base must be 9 inches?

Answers

You have the formula... V = pi * R^2 * h

4752 in^3 = 3.14 * 9"^2 * h (with the numbers plugged in)

4752 in^3 = 3.14 * 81"^2 * h (with the squaring math completed)

4752 in^3 = 254.14"^2 * h (with the multiplication math completed)

4752 in^3 / 254.14"^2 * h / 254.14"^2 (showing the division from both sides to get "h" alone)

18.68" = h (the answer)

Then people start talking about freedom an Escape from Britain not long after the Revolutionary War is happening. Once 7 years passed the war is over.declaring independence was justified especially after the Intolerable Acts. However the war may had been avoided if they just let them have their freedom in instead of having a war that lasted 7 years. yet the whole thing could have been avoided, if the British did not keep such a tight hold on the colonists, gave them representation in parliament, and gave them the birthrights they desperately wanted. A counterclaim may be that the war was justified and declaring independence was not. The British were the first ones to fire sparking the war therefor making it justified. may be considered Declaring independence was not justified given they could have stayed and then everything would have stayed the same.however looking at the details you can see that declaring independence was very much justified particularly because they wanted to get away from the Intolerable Acts and the Boston Massacre and they had every right to.
