(multiple choice) plz help me!!

x is the missing side (x > 0)

because this is a right triangle, using Pythago theorem, we have:

x² + 4² = 12²

⇔ x² = 12² - 4²

⇔ x² = 128

=> x ≈ 11.3

Step-by-step explanation:

answer

see attachment

explanation

the given function is

this function has y-intercept at

-4 and a slope of 2.

note that, the graph has a positive slope.

the graph that represents this function is the straight line that moves upward from left to right.

the graph touches the y-axis at -4.

the correct choice is the graph shown in the attachment.

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer
