Answer:

<h2>\huge \: \boxed{ \boxed{21}}</h2>

Step-by-step explanation:

according to the question

\frac{14}{2x + 7}  =  \frac{x - 3}{63}

882 = (x - 3)(2x + 7)

0 =882 -  (x - 3)(2x + 7)

882 - (2 {x}^{2}  + x - 21) = 0

882 -  {2x}^{2}  - x  + 21 = 0

- {2x}^{2}  - x + 903 = 0

2x + x - 903 = 0

(2x + 43)(x - 21) = 0

x =  -  \frac{43}{2}  \\ x = 21

\huge \therefore x = 21

!!URGENT!!WILL GIVE BRAINLIEST!! GEOMETRY DILATIONS!!! PLEASE INCLUDE EXPLANATION
Sergeu [11.5K]

Unless otherwise specified we usually assume the dilation is about the origin. That is you can tell the scale factor by the way the distance to the origin changes.

Point C, for example, is 6 units from the origin. Its image, C' is 4 units from the origin. Then the scale factor image/original is 4/6 = 2/3.

Your green question mark gets filled with 3 to make the fraction 2/3.

_____

To find the translation, pick any point on A'B'C' and find the corresponding point A'', B'', or C''. Count the squares you have to go left to get from A' to A'', for example. That will be 5 to the left. Similarly, count the squares you have to go down to get from A' to A''. That will be 4 down.

I WILL GIVE 20 POINTS TO THOSE WHO ANSWER THIS QUESTION RIGHT NOOOO SCAMS AND EXPLAIN WHY THAT IS THE ANSWER
professor190 [17]

Answer:

25

Step-by-step explanation:

The formula for the Pythagorean Theorem is:

\sqrt{a^2+b^2}=c

Now,

A=7

B=24

7x7=49

24x24=576

Add,

576+49=625

Last,

Take the square root of 625

The square root of 625 is 25

c=25

To Check if the hypotenuse is correct:

a^2+b^2=c^2

7^2+24^2=25^2

7x7=49

24x24=576

25x25=625

49+576=625

625=625,

Therefore the hypotenuse is 25.

bixtya [17]

There are four properties involving multiplication that will help make problems easier to solve. They are the commutative, associative, multiplicative identity and distributive properties. Multiplicative Identity Property: The product of any number and one is that number. For example 5 * 1 = 5.
