Answer:

A. {3,4}

Step-by-step explanation:

In order to find the x values which would make the entire function undefined, you would have to factor the bottom equation. Factoring x^2+7x+12 gives you (x+3)(x+4). If you set each of these equal to 0, you end up with the x values being 3 and 4.

Solve for x in the diagram below (picture included)
Sever21 [200]

Answer:

34

Step-by-step explanation:

We know the straight line is equal to 180°, and the three angles that make it are (x+12),100°, and x. We can use the equation 180=(x+12)+100+x to find x.

180=(x+12)+100+x

We can remove the parentheses and combine x plus x to 2x.

180=100+2x+12

100+12=112

so

180=112+2x

-112 -112

68=2x

A right triangle has a leg that measures 15 ft and the hypotenuse measures 24 ft. What would the
Serhud [2]

Answer:

x=19

Step-by-step explanation:

First, you place the numbers in place of the variables in their relative positions using the pythagorean theorem:

15^{2} +x^{2}=24^{2}

Then you square the numbers that you currently have:

225+x^{2}=576

Then subtract 225 from both sides to isolate the x:

x^{2} =576-225

This gives you the equation:

x^{2} =351

Then take the square root of both sides which gives you:

x=18.7349939952

Then round to the nearest whole number which gives you x=19
