Answer:

<h2>The slope of BC is -7/2.</h2>

Step-by-step explanation:

<h3>Givens</h3>

ABCD is a rectangle.

AB \parallel CD

BC \parallel AD.

m_{AB} =\frac{2}{7}

We know that AB \perp BC and CD \perp AD, by definition of rectangle.

Additionally, m_{AB} \times m_{BC}=-1, by condition of perpendicularity.

Replacing, we have

\frac{2}{7}  \times m_{BC}=-1\\ m_{BC}=-\frac{7}{2}

Therefore, the slope of BC is -7/2.

What is the value of the following expression?2 x [(12 + 2) x 5] + 32 divided by 2 number on top right 3
a_sh-v [17]

The value of the expression is 141.5

Explanation:

The expression is $2 \times[(12+2) \times 5]+\frac{3}{2}$

The value of the expression can be determined using the rule PEMDAS.

According to the PEMDAS rule, first we need to perform the operation which is within the parenthesis.

Thus, the expression becomes,

$2 \times(14 \times 5)+\frac{3}{2}$

Multiplying the values within parenthesis, we have,

$2 \times70+\frac{3}{2}$

Using PEMDAS, we need to multiply the numbers.

$140+\frac{3}{2}$

Again using PEMDAS rule, divide the number,

140+1.5

Finally, using PEMDAS, let us add the values, we have,

141.5

Thus, the value of the expression is 141.5

How do how you cross cancel multiplying fractions
DENIUS [597]

It's easy once you spot the ones that can cross cancel!

Say we have the fractions 8/10 and 20/23. \frac{8}{10} \frac{20}{23} (it's easier to see on top of each other)

If you look diagonally , so 8 and 23 and 10 and 20, you can see that 10 and 20 have a common factor. So we divide it by the highest common factor to reduce those numbers, making it easier to multiply. 10 and 20 can become 1 and 2, dividing by 10. So now we are left with 8/1 and 2/23, and now we multiply normally going across so 16/23.

This works going both diagonals and simplifying both, but in that case it would be easier to try and simplify the fractions before cross multiplying them.

Basically: look for those diagonals and if they can be divided down by the highest common factor, go for it to make it easier to multiply normally afterwards.

Hope I helped!
