False, parallel lines will never touch each other. If lines are parallel it means that they can go on forever without ever touching each other.

Hope this helps :) Let me know if there's anything else I can help you with :)

A spinner is divided equally into four colors, red, green, yellow and blue. Find the sum of the probabilities of spinning red, g
grandymaker [24]
Probability=number of specific outcomes / total number of possible outcomes...

Since they want to know the probability of getting all of the colors the probability is just one.

The sum of all probabilities is always equal to one.  In this case:

1/4+1/4+1/4+1/4=1

ABCD is a trapezium with AB= x cm, DC=( x+ 4 )cm and the distance between the parallel sides AB and DC is 1/2 x cm
horsena [70]

We know that the smaller base is x cm, the greater base is x+4 cm, and that the height is x/2 cm.

Since the area of a trapezium is given by

A=\dfrac{(b+B)h}{2}

If we plug the expressions we have

A=\dfrac{(x+(x+4))\frac{x}{2}}{2}=\dfrac{(2x+4)x}{4}=\dfrac{2x^2+4x}{4}

If this must equal 84, we can solve for x as follows: start with

\dfrac{2x^2+4x}{4}=84

Multiply both sides by 4:

2x^2+4x=336

Subtract 336 from both sides:

2x^2+4x-336=0

We can divide both sides by 2 to make computation simpler:

x^2+2x-168=0

Use the quadratic formula (or any mean you prefer) to solve this equation and get the solutions

x_1=-14,\quad x_2=12

We can't accept the negative solution, because it would imply

AB=-14,\quad CD=-10

and we can't have negative side lengths. So, the answer is 12.

Write an algebraic expression
Flura [38]

Answer:

1. k + 2 (or other way around, it doesn't matter)

2. PY or P×Y

3. 10 - z

Step-by-step explanation:

1. You are adding here, so you add the two terms together.

2. If we had the amount of rulers and how much they cost, we could multiply to find these. Since we don't, we just leave the two variables to be multiplied.

3. It is asking the difference between two numbers, meaning that you need to subtract. With these types of problems, you always use the first number that appears in the problem to start the expression. For instance, if it had listed z first, then you would have done z - 10.
