The answer is D, no solution
Answer:
C) CA=40
Step-by-step explanation:
2y/(2y+4)=(2y+6)/4y
cross multiply
8y²=4y²+20y+24
4(2y²)=4(y²+5y+6)
divide both sides by 4
2y²=y²+5y+6
y²-5y-6=0
(y-6)(y+1)=0
So the answer must be either 6 or -1. Since it can't be a negative number, it must be 6.
CA=2(6)+4+4(6)
CA=12+4+24
CA=40
Answer:
<em>b = 12 cm</em>
Step-by-step explanation:
<u>The Pythagora's Theorem</u>
The area of a square of side length x is

We have three squares, two of which have side lengths of a=5 cm and b= 13 cm.
The combined area of the smaller squares is the same as the area of the largest square. We cannot say at first sight which square is the largest, we'll assume the square of side length of 13 cm is the largest one. Thus:

Where b is the unknown side length.
The above expression corresponds to the Pythagora's Theorem formula. Solving for b:


b = 12 cm
We can solve this problem by division- What information can we gather?
- The ball reaches half its original hight each time it bounces, which is another way of saying it divides by 2 each time
- If we divide 16 by 2, we get 8.
- If we divide 8 by 2, we get 4
- If we divide 4 by 2, we get 2.
<em>The answer is 2</em>
Hope this helps!
