Answer: x=3.75

Step-by-step explanation:

For this exercise you need to apply the Intersecting Chords Theorem.

In this case, based on that Theorem, you can write the following equation:

CE*DE=AE*BE

You can identify in the picture that:

CE=x\\\\DE=8\\\\AE=6\\\\BE=5

Now, knowing those values, the next step is to substitute them into the equation:

CE*DE=AE*BE\\\\x*8=6*5

Finally, you need to solve for "x" in order to find its value. You get that this is:

8x=30\\\\x=\frac{30}{8}\\\\x=3.75

Answer:

x=3.75\ units

Step-by-step explanation:

we know that

(AE)(EB)=(CE)(ED) ----> by Intersecting Chords Theorem

substitute the given values

(6)(5)=8x

solve for x

x=\frac{30}{8}

x=3.75\ units

Find the TWO integers whos product is -12 and whose sum is 1<br>m​
svetoff [14.1K]

Answer:

\rm Numbers = 4 \ and \ -3.

Step-by-step explanation:

Given :-

The sum of two numbers is 1 .

The product of the nos . is 12 .

And we need to find out the numbers. So let us take ,

First number be x

Second number be 1-x .

According to first condition :-

\rm\implies 1st \ number * 2nd \ number= -12\\\\\rm\implies x(1-x)=-12\\\\\rm\implies x - x^2=-12\\\\\rm\implies x^2-x-12=0\\\\\rm\implies x^2-4x+3x-12=0\\\\\rm\implies x(x-4)+3(x-4)=0\\\\\rm\implies (x-4)(x+3)=0\\\\\rm\implies\boxed{\red{\rm x = 4 , -3 }}

Hence the numbers are 4 and -3.

Distributive property pls helpp
GaryK [48]

9514 1404 393

Answer:

  • 4
  • 16

Step-by-step explanation:

If you consider matched parentheses to identify the contents of a "bag", the multiplier outside parentheses tells you how many bags you have. When you use the distributive property, you effectively dump all those bags on the table.

Here, the expression 4(6v +4) tells you there are 4 bags and each one contains 6v and 4. When you open them all up, you have ...

  4(6v +4) = 6v +6v +6v +6v +4 +4 +4 +4

Of course, we can use multiplication to simplify repeated addition, so we can also write this as ...

  4(6v +4) = 4·6v +4·4 = 24v +16

The numbers that go in your boxes are identified by their bold font style.

RSB [31]

set up an equation for this.  x will be the score of the losing team.  x+2x=96.  Then solve for x.  3x=96.  x=96/3 x=32.  So the losing team got 32 points and the winning team got 64
