Answer:

The answer is x=12

Step-by-step explanation:

In order to determine the "x" value, we have to know about the tangent to a circle.

The line that joins two infinitely close points from a point on the circle is a Tangent. It means, the lines that intersect the circles exactly in one single point are tangents.

I have attached an image that shows a tangent to a circle. Also there is a formula that relates the segments of the circle.

According to the same notation of the image:

PS^2=PQ*PR

In this case:

PS=6\\PQ=3\\PR=x\\6^2=3*x\\x=\frac{36}{3}=12

Finally the answer is x=12

A rectangular painting is made up of two congruent squares with sides that are 2 feet long. What is the area of the entire paint
solniwko [45]

Answer:

8 feet²

Step-by-step explanation:

The sides of each square are equal, so the area of one square is 4 feet². If you add the area of that square to the other (which has the same area) you get 8 feet².

Another way to solve it:

Visualize in your head or draw a picture of one of the squares right on top of the other. Combined, the length and width of the rectangle are 2 feet and 4 feet. Since the formula for area is <em>lw=a </em>(<em>l</em>=length, <em>w</em>=width, and <em>a</em>=area)<em>, </em>you multiply 2 by 4 and get 8. Therefore, the area of the painting is 8 feet². Hope this helps.

the function f(x) = –x2 − 2x 15 is shown on the graph. what are the domain and range of the function? the domain is all real num
VMariaS [17]
-x^2 - 2x + 15 in vertex form is -(x^2 + 2x - 15) = -(x^2 + 2x + 1 - 16) = -(x + 1)^2 + 16

Therefore, domain is all real numbers and range is {y|y ≤ 16}.
