Answer:

d.  x = -3

Step-by-step explanation:

<u />\sqrt{(x + 3)}÷ (x+8)(x-2) = 0

f(x) / g(x) = 0

Variable x cannot be equal to any of the values −8,2 since division by zero is not defined. Multiply both sides of the equation by (x−2)(x+8).

<u />\sqrt{(x + 3)} = 0 ------ square both sides

x + 3 = 0

solve for x:

x = -3

A bag contains 9 marbles: 4 are green, 3 are red, and 2 are blue. Susan chooses a marble at random, and without putting it back,
Valentin [98]

The probability of picking blue is the number of blue marbles/ total marbles.

For the first pick there are 2 blue marbles and 9 total marbles so the probability of picking blue would be 2/9

After picking the first marble there would be 1 blue marble left and 8 total marbles. The probability of picking the blue marble would be 1/8

To find the probability of picking both, multiply the probability of each one by each other:

2/9 x 1/8 = 2/72, which reduces to 1/36

The answer is 1/36

The measures of complementary angles have a sum of 90 degrees.Angle A and angle B are complimentary, and their measures have a d
777dan777 [17]

Answer:

The measure of the angles are 55° and 35°

Step-by-step explanation:

Sum of two angles that are complement of each other are 90.

The angles are A and B, so we can write:

A + B = 90

Also,

The difference is 20. Let A be the greater of them, so we can write equation 2 as:

A - B = 20

Now, we add up both equations, eliminate B and solve for A first:

A + B = 90

A - B = 20

---------------

2A = 90 + 20

2A = 110

A = 110/2

A = 55

And now the measure of B:

A + B = 90

55 + B = 90

B = 90 - 55

B = 35
