Answer:
2nd row, circle is <u><em>6</em><em>x</em><em> </em><em>+</em><em> </em><em>2</em><em>y</em></u><em>.</em>
3rd row, rectangle is <u><em>3</em><em>x</em><em> </em><em>+</em><em> </em><em>y</em></u><em> </em>and circle is <u><em>5</em><em>x</em></u><em>.</em>
Step-by-step explanation:
As the question say when 2 rectangles, at the sides are add up together, it will form circle in the middle. So in order to find circle or rectangle, you either have to add or substract :
For 2nd row, circle,
T/L(r) + B/R(r) = M(c)
4x + 3y + 2x - y = M(c)
6x + 2y = M(c)
M(c) = 6x + 2y
For 3rd row, rectangle,
T/L(r) + B/R(r) = M(c)
x + 4y + B(r) = 4x + 5y
B(r) = 4x + 5y - x - 4y
= 3x + y
For 3rd row, circle,
T/L(r) + B/R(r) = M(c)
2x - y + 3x + y = M(c)
5x = M(c)
M(c) = 5x
* Take note, for 3rd row, you first have to find the rectangle then circle.
Symbols :
- T/L(r) = Top/Left (rectangle)
- B/R(r) = Bottom/Right (rectangle)
- M(c) = Middle (circle)
Answer:
-(-9) is 9
Step-by-step explanation:
-(-9)
(when there are two negatives multiplyed with eachother, the product will be postive)
+ 9
+ 9 = 9

Suppose f(x) = ----------
sqrt(x)
8
What if we let x = 16 (just an example)? We'd get f(16) = ------------- = 2.
sqrt(16)
What if we let x = g(x) = 2x+4?
We'd get the following:
8
f(g(x)) = -------------- = y
sqrt(2x+4)
So...the correct answer is the fourth one.
