Answer:

x=3\sqrt 5\\

y = \sqrt {126}

Step-by-step explanation:

By geometric mean property:

x =  \sqrt{9 \times 5}  =  \sqrt{45} = 3 \sqrt{5}   \\  \\ by \: pythagoras \: theorem \\  \\  {y}^{2}  =  {9}^{2}  +  {x}^{2}  \\  \\  {y}^{2}  =  {9}^{2}  +  {(3 \sqrt{5}) }^{2}  \\  \\  {y}^{2}  = 81 + 45 \\  \\  {y}^{2}  = 126 \\  \\ y =  \sqrt{126}

Katy buys 4 DVDs every 2 weeks how many will she buy in 10
malfutka [58]

If she maintains her average amount of movies bought every week, then she will buy 20 DVDs in 10 weeks. Explanation: she buys 4 every week, so if we want to find out how many are in 10 weeks, we must multiply two until we get to 10 ( five weeks ) then multiply that buy her average of movies. And that is how we get the answer of 20 DVDs! ( her at least I did )

Anyways, hope this helps!

HELP URGENTLY 1 QUESTION PLEASE SUPER QUICC
Zepler [3.9K]

So the formula for the area of a triangle is A=\frac{1}{2} bh (b = base, h = height). In this case, by counting from (-3,-3) to (-3,2) the height is 5 and the base is 4 counting from (-3,2) to (1,2).


Using this info, we can form the equationA=\frac{1}{2} *4*5 and solve from there.


A=\frac{1}{2} *4*5\\ A=\frac{1}{2} *20\\ A=10
