9514 1404 393

Answer:

  both C and D are correct

Step-by-step explanation:

The diagram shows that x is the total of $40 and 20% of $40.

Description A would be represented by the difference of $40 and 20% of $40, not the sum.

Description B would be represented by 20% of $40, not the sum of that and $40.

Both descriptions C and D are properly represented in the diagram.

Afina-wow [57]

Answer:

Step-by-step explanation:

By using the Pythagorean theorem:

b^2+3^2=5^2
b^2+9=25

b=sqrt (25-9)

b=sqrt(16)

b=4

=> 4^2+7^2=c^2
16+49=c^2
65=c^2
=>c=sqrt(65)

c = (approximately) 8

Please help ASAP !!!
enot [183]

Answer: x=3

Step-by-step explanation:

To solve this problem you must apply the proccedure shown  below:

- Multiply both sides of the equation by 3:

3(2x-3)=3(\frac{x^2}{3})\\6x-9=x^{2}

- Now you must make the equation equal to zero as following:

6x-9=x^{2}\\x^{2}-6x+9=0

- Factor it, as you can see below. Therefore, you obtain the following result:

(x-3)(x-3)=0\\(x-3)^2=0\\x=3
