what is the answer to this:
4 + c, when c = 10

Answer:

90 cm²

Step-by-step explanation:

Given that both triangles are similar, it follows that the ratio of their area equals the square of their corresponding sides.

Let the area of the other triangle be x. Therefore:

[tex] \frac{10}{x} = \frac{4^2}{12^2} [/tex]

[tex] \frac{10}{x} = \frac{16}{144} [/tex]

Cross multiply

[tex] 10*144 = 16*x [/tex]

[tex] 1440 = 16x [/tex]

Divide both sides by 16

90 = x

Area of the other polygon = 90 cm²

Answer:

Answer is 90

Answer:

B. (1, 0)

Step-by-step explanation:

9514 1404 393

Answer:

  B.  (1, 0)

Step-by-step explanation:

You can count grid squares on the graph to find the point that is 4 of the 8 units horizontally between the points, and 2 of the 4 units vertically between the points. That will be ...

  C +(4, 2) = D -(4, 2) = (1, 0)

__

Or, you can use the midpoint formula:

  M = (C +D)/2

  M = ((-3, -2) +(5, 2))/2 = (-3+5, -2+2)/2 = (2, 0)/2

  M = (1, 0)

The midpoint is (1, 0).

Answer: -6<x<5

Step-by-step explanation:

Given

Length is 3 m more than three times the width

Suppose width is x

So, the length is 3x+3

The area of a rectangle is  [tex]length\times width[/tex]

Area= [tex](3x+3)x<90[/tex]

[tex]\Rightarrow 3x^2+3x-90<0\\\Rightarrow x^2+x-30<0\\\Rightarrow x^2+6x-5x-30<0\\\Rightarrow (x+6)(x-5)<0\\\Rightarrow -6<x<5[/tex]

Daniel is rollerblading at 15 miles per hour

Daniel can go 3 miles in 12 minutes so we do 12÷3 to find out how many minutes it takes to go 1 mile which is 4 now we do 60÷4 to get 15

Alternatively we could do 60÷12 to get 5 then do 3×5 to get 15

Step-by-step explanation:

the equation on finding slope is y2 - y1/x2 - x1

so it is...

6 - 6 = 0

6 - -5 = 11

0/11 but that doesnt work so I believe the slope is zero because the denominator is not the one being a 0

hope I helped ;)

Answer:

The value of x is 26.

Step-by-step explanation:

In a triangle, the total angles is 180°. In order to find the value of x, you have to add up all the angles in terms of x and make it equals to 180°

2x + 3x + 50 = 180

5x + 50 = 180

5x = 180 - 50

5x = 130

x = 130 ÷ 5

x = 26

As we know that,

Sum of all angles of triangle = 180°

Given,

Angles are 2x , 3x and 50°

Now,

[tex] \rightarrow \: 2x + 3x + 50 = 180[/tex]

When plus sign goes to another side then,it become minus.

[tex] \rightarrow \: 5x = 180 - 50[/tex]

[tex] \rightarrow \: 5x = 130[/tex]

[tex] \rightarrow \: x = \cancel \dfrac{130}{5} [/tex]

[tex] \rightarrow \: x = 26[/tex]

Hence,the value of x is 26°.

Answer:

8

Step-by-step explanation:

8*4 is 32 8*9 is 72

so, it is 8

since it is distributive property 8(4+9)

Answer:

8

Step-by-step explanation:

1) simplify the equation

32+72=104

104=4x+9x (distibute the "x")

104=13x

x=8

hence the "blank" is 8

Answer:

I'm in 10th grade so I'll see what I can do and will answer to the best of my ability.

Step-by-step explanation:

What Julie did wrong was, she did simplify she just did it wrong. She used 4*8 which does equal 32 but 8 can't be simplified anymore than that. If she would of used 2*16 then her answer would be right.

Hope this helps!

Answer:

[tex]5 \sqrt{18} - \sqrt{32} \\ = 5 \sqrt{9 \times 2} - \sqrt{4 \times 4 \times 2} \\ = 5 \times 3 \times \sqrt{2} - 2 \times 2 \times \sqrt{2} \\ = 15 \sqrt{2} - 4 \sqrt{2} \\ = \boxed{11 \sqrt{2} }[/tex]

Step-by-step explanation: multiply 12.5 by 16

Answer:

1.75

Step-by-step explanation:

Since the curtains are going up in .25. We need to add .25 to 1.5.

1.5 + .25 = 1.75

The length of curtains will Riya buy is 1.75 m.

A sequence is an arrangement of numbers in a specific order. A series, on the other hand, is defined as the sum of the elements in a sequence.

For example,  In the sequence 1, 3, 5, 7, 9, …, 1 is the first term, 3 is the second term, 5 is the third term, and so on.

We have length of curtains as

1m, 1.25 m, 1.5 m,...

Now, from above the first term is 1.

Common difference, d= 1.25 - 1 = 0.25

So, the next length of curtain will be

= 1 + (4-1)0.25

= 1 + 0.75

= 1.75 m

Answer:

3 x − 7

Step-by-step explanation:

Answer:4 gallons of water ... 30 plants

x gallons of water = ? ... 45 plants

If you would like to know how much water will it take to water 45 plants, you can calculate this using the following steps:

4 * 45 = x * 30

180 = 30 * x    /30

x = 180 / 30

x = 6 gallons of water

Result: You will use 6 gallons of water to water 45 plants.

Answer:

-8

Step-by-step explanation: since it says Times, (for me times is multiplication) you would multiply -2 and 4. negative 2 would be from that person losing 2 points. and 4 since it is your total amount of times you have forgotten to write your name. so, -2 x 4 = -8.

how i got -8. both signs from -2 and 4 are different, and when they are different the answer will always be negative.

A parallelogram is a quadrilateral that has two pairs of parallel sides.

In a parallelogram, opposite sides and angles are equal.

The adjacent angles add up to 180 degrees.

We have,

Three vertices of the parallelogram ABCD.

A = (0, 2)

B = (8, 1)

D = (3, 4)

C = (x, y)

        A___________B

         /                       /

       /          O          /

     /                       /

   D                     C

Now,

AO = OC

BO = DO

O is the midpoint of BD.

O =(m, n)

m = (8 + 3) / 2

m = 11/2

n = (1 + 4)/2

n = 5/2

O = (11/2, 5/2)

Now,

O is the midpoint of AC.

m = (x + 0)/2

11/2 = x/2

x = 11

n = (y + 2)/2

5/2 = (y + 2)/2

y + 2 = 5

y = 3

The coordinates of C.

= (x, y)

= (11, 3)

Thus,

The coordinates of vertex C are (11, 3).
