Answer:
option c
Step-by-step explanation:
if y= x^2 e^x then the derivative is x^2 * e^x + e^x * 2x
take e^x and x as commom so we get e^x * x ( x+2)
Hey there! :D
The biggest thing to remember here is the similar triangles and their side lengths.
Okay, so we can separate these triangles into 3 similar triangles. Which, we only need to do that to two for a proportion, but if you were to have more variables, you could separate the triangles even more if you needed to.
We want to find two triangles that have "x" has a value of their side, so we can solve a proportion.
The bigger triangle, (the whole two triangles combine) and the smaller triangle on the left can be used to make a proportion.
On the smaller triangle:
We have 9 cm on the shorter side and x as the hypotenuse.
On the larger triangle:
We have x as the shorter side, and then 25 as the hypotenuse. (9+16)
Note: You have to flip the larger triangle upside down to make it a similar structure to the other two triangles. It is similar, you just have to flip it.
So, now we can make a proportion.

Now, cross multiply.
9*25= 225
x*x=

So, find the square root.
√225= 15
x= 15. I hope this helps!

Answer:
y is 8
Step-by-step explanation:
First u do 13y-9y=4y
so you then have 4y-5=27
then you plus 5 to 27
u then have 4y=32
then divide 32 by 4
so you will get y=8
Answer:
A rational expression is when the numerator and the denominator are polynomials. An example is 5/x − 2
