The complete question is:
quadrilateral ABCD is a rectangle (see attached image)
If BE = 6y + 2 and CE = 4y + 6, find the value of y

Answer:
y = 2

Explanation:
We are given that the quadrilateral ABCD is a rectangle. This means that it has the following properties:
1- Its diagonals are equal. This means that: AC = BD
2- Diagonals bisect eqcah other. This means that: BE = ED and AE = EC

From the above, we can infer that:
BE = CE
This means that:
6y + 2 = 4y + 6
6y - 4y = 6 - 2
2y = 4
y = 4/2
y = 2

Hope this helps :)

Rearrange the equation so u is the independent variable. -12u+13=8w-3 <br><br> w= ___
Rama09 [41]

Answer:

w = \frac{-12u+16}{8}

Step-by-step explanation:

Reverse the equation placing w on the left side

8w - 3 = - 12u + 13 ( add 3 to both sides )

8w = - 12u + 16 ( divide both sides by 8 )

w = \frac{-12u+16}{8}

Can somewon help me plz can somewon help me
Karolina [17]

Hey there! I'm happy to help!

Let's look at our diameters.

1*10^2^1\\5*10^2^2

We want to see how many times greater the diameter of the IC 1101 is than the Milky Way. So, we will divide it's diameter by the diameter of the Milky Way.

\frac{5*10^2^2}{1*10^2^1} \\

We divide the numbers without exponents, giving us 5. Then, we divide the 10s with exponents. When dividing exponents, you subtract the numbers in the exponent to get your result. For example, x³÷x²=x

\frac{5*10^2^2}{1*10^2^1} = 5*10=50

Therefore, your answer is 50.

Have a wonderful day! :D

What number must be added to the expression below to complete the square? x^2-9x
pantera1 [17]

Answer:

A.81/4

Step-by-step explanation:

x^2-9x

This is in the form x^2 + bx

To complete the square, we take b/2  then square it and add it

b =-9

b/2 = -9/2

(b/2) ^2 = (-9/2) ^2 = 81/4

Please ignore my work. Can you please solve and show all work, thanks
valina [46]

Answer:

Answer is (1): 2 times (x^2 -13)

Step-by-step explanation:

Using the FOIL method, you can conclude that (x-5)(x+5) is X^2 -5x +5x -25. Since the two middle terms cancel, you are left with X^2 -25. For the right side of the equation, (x-1)(x+1), using the FOIL method gets you x^2 -x +x -1. Once again, the -x and x cancel out and you end up with X^2 -1. To add both of these together, you can get rid of all parentheses and do the work. Two x^2 added together is 2X^2, and -25-1 is negative 26. After this, you end up with 2x^2 -26. To get to your final answer you need to take out the GCF of both terms, (the largest number that can go into 2x^2 and -26), which is 2. Taking the two out leaves us with 2(x^2 -13), which is your final answer. It looks like you were on the right track.

FOIL Property

Multiply first terms

Then Outside terms

Then inside terms

Then the last terms

Hope this helps!
