AB = x + 2

Mathematics
1 answer:
LUCKY_DIMON [66]3 years ago
3 0

Answer:

AB = 7, DC = 7, AD = 5, BC = 5

Step-by-step explanation:

If you set AB equal to DC you get:

x+2=12-x

2x=10

x=5

If you set AD equal to BC you get:

2y-5=Y

y=5

Solve for each side of the quadrilateral and you get:

AB = 7, DC = 7, AD = 5, BC = 5

If x and y vary inversely and x = 5 when y = -3.5, what is the value of x when y = 10?
Solnce55 [7]

Answer:

Step-by-step explanation:

k = xy

Putting values of x and y in the equation

k = (5)(-3.5)

= - 17.5

Finding value of x when y = 10

k = xy

- 17.5 = x10

Bringing like terms on one side

- 17.5 - 10 = x

-27.5 = x

Simplify.<br> 8√2 / 6-3√8
Sonbull [250]

 The rationalized expression in general term is given by: (-8 -4√2) / 3

<h3>What is rationalization?</h3>

  Rationalization is a mathematical operation that allows us to determine or eliminate a root of the denominator of a fraction, so that it can be expressed in linear form, either decimal or integer, by the product of a root.

  As defined above, we must perform a mathematical operation to eliminate the root of the denominator without altering the value.

(8√2 / 6-3√8 ) Multiply by  ( 6+3√8)/( 6+3√8)

(8√2 / 6-3√8 )( 6+3√8)/( 6+3√8)

8√2(6+3√8) / (6-3√8)²  Expand the denominator using the FOIL method.

8√2(6+3√8) / (36 - 18√8 + 18√8 - 72)

8√2(6+3√8) / -36

48√2 + 24√2√8 / -36  ::::.   √8 = 2√2

48√2 + 96 / -36

-12(4√2 + 8) / 12x3

(-8 -4√2) / 3 is the result.
