Hi there!

it is -3x-2+x-3..

When two parentheses are together, this means to add both parentheses..

<u><em>1.Cancel the parentheses:</em></u>

<u><em /></u>(-3x-2)(x-3)=-3x-2+x-3<u><em /></u>

The final result would be -3x-2+x-3..

Your friend shows you a coin collection. In it 45/50 of the coins are quarters. what percent of the coins are quarters?
Ksenya-84 [330]

Answer:

90% of them are quarters.

Step-by-step explanation:

If you take 50 and multiply it by two, you get 100. But, in order to get the right number, you have to multiply 45 by two as well. 45 x 2 is 90. 90 out of 100 is 90 percent. So 90% is the answer.

What must be true for lines a and b to be parallel lines? Select two options.
Rasek [7]

The expression that must be true for a to be parallel to b are mAngle2 = 58Degrees and <1 = 4x - 10

<h3>Lines and angles</h3>

A line is the shortest distance between two points and the point where two lines meet is known as an angle

From the figure shown

m<2 = 58 degrees (alternate exterior angle)

Since the sum of angles on a straight line is 180 degrees, hence;

3x-1+<2 + 4x - 10= 180

3x-1 + 58 + 4x - 10 =180

7x + 47 = 180

7x = 180- 47

7x = 133

x = 19

Hence the expression that must be true for a to be parallel to b are mAngle2 = 58Degrees and <1 = 4x - 10

A parabola whose equation is y = (x - 5)^2 - 2 has a vertex at _____.
