a rectangle has perimeter 86 cm and length 37 cm. what is its width

Answers

Answer:

6 cm

Step-by-step explanation:

37 × 2 = 74 cm86 - 74 = 12 cm12 ÷ 2 = 6 cmSo, the width is 6 cm

I hope this helps!

Answer:

The rectangle's width is 6.

Step-by-step explanation:

You are given the perimeter is 86 cm. The perimeter is the sum of all the sums. For a rectangle, use the formula, P = 2l + 2w. So, we plug the given into our equation: P = 86, l = 37. This results in:

86 = 2(37) + 2w

86 = 74 + 2w

Subtract 74 on each side.

2w = 12

Then, divide each side by 2.

w = 6

Hopefully this helped. And good luck in your studies.

Answers

Answer:

x = -9 1/2

y = -16 1/2

Step-by-step explanation:

x - y = 7

solve the above for 'y':  -y = 7 - x

multiple each side by -1:  y = x - 7

now both equations are in 'y=' form

x - 7 = 3x + 12

-2x - 7 = 12

-2x = 19

x = -19/2 or -9 1/2

-9.5 - y = 7

-y = 16.5

y = -16.5 or -16 1/2

                                       

Answer:

(-19/2, -33/2)

3015³

Step-by-step explanation:

Hellllloooo!

One last time why dont we.

This time we are given a cylinder to find the area of which is pretty fun ngl.

Lets take a look at the formula for a cylinder :

Volume = [tex]\pi[/tex] x r² x h

Now this may look weird cause that house thing is for sure not a number but trust me it is easy once you know what you're looking at.

So that house thing is called pi, and really it is worth 3.14 just it looks like that for some reason. But it is used to find the area of circles.

So what we are going to do is find the area of the circle which is the base of the cylinder and multiply it by the height to find the total area.

Again lets see what we are given :

Radius = 8

Height = 15

Now we plug this into the formula :

Volume = [tex]\pi[/tex] x r² x h

Volume = [tex]\pi[/tex] x 8² x 15

(don't forget your little 2 after the radius (8))

So first lets do pi x 8²

=

Which gives us roughly around 201

So now we have the surface area of the base circle of this cylinder, all we have to do is multiply by the height.

So :

201 x 15

=

3015³

(don't forget your little 3 cause its 3D)

But that is your answer.

I hope this helps!

If f(1) = 2 and f(n+1) = f(n)^2 – 3 then find the value of f(3).

Answers

Answer:

The value of f(3) = -2.

Step-by-step explanation:

First of all, let's find f(2).

[tex]f(n+1)=f(n)^{2}-3[/tex]

[tex]f(1+1)=f(1)^{2}-3[/tex]

[tex]f(2)=f(1)^{2}-3=2^{2}-3=1[/tex]

Now, we can find f(3):

[tex]f(2+1)=f(2)^{2}-3[/tex]

[tex]f(3)=f(2)^{2}-3=1^{2}-3=-2[/tex]

Therefore, the value of f(3) = -2.

Step-by-step explanation:

Answer:

5x - 11 = 17

Step-by-step explanation:

Five times a number is 5x when the number is unknown.

The difference between that number and 11 is (difference means subtract)

5x - 11

All of which = 17

5x - 11 = 17

Find the polynomial of least degree in standard form with the given roots:
x = 2, 3i

Answers

Answer:

x^3 - 2x^2 + 9x - 18.

Step-by-step explanation:

The complex roots occur in conjugate pairs so there are 3 roots 2, 3i and -3i.

So we have:

P(x) = (x - 2)(x - 3i)(x + 3i)

= (x - 2)(x^2 - 9i^2)

= (x - 2)(x^2 - 9*-1)

= (x - 2)(x^2 + 9)

= x^3 + 9x - 2x^2 - 18

= x^3 - 2x^2 + 9x - 18.
