Complete the following: (2x +3y)^2 = (2x)^2+2(2x)(3y) +(____)^2
FrozenT [24]

Answer:

Complete function will be  (2x+3y)^2=(2x)^2+(3y)^2+2\times (2x)\times (3y)

Step-by-step explanation:

We have given equation (2x+3y)^2=(2x)^2+2\times (2x)\times (3y)+..........^2

We have to find the function in place of blank space and complete the function

We know the algebraic equation (a+b)^2=a^2+b^2+2ab

So (2x+3y)^2=(2x)^2+(3y)^2+2\times (2x)\times (3y)

So in place of blank pace there will be (3y)^2

And complete function will be  (2x+3y)^2=(2x)^2+(3y)^2+2\times (2x)\times (3y)

A bus travels at a constant speed of 48 km/h. How long will it take to travel 600 km?
grigory [225]

Answer:

It will take 12 and 30 hours

Step-by-step explanation:

To solve this, you need to divide by <u>distance needed to travel by the speed</u>

600/48 is equal to 12.5 hours.

.5 hours is equal to 30 mins because 60mins times .5 is 30 minutes, therefore <u>the final answer is 12.5 hours</u>

I hope this helps :)

you should have $16 and a coupon for a $5 discount at a local supermarket. a bottle of olive oil costs$7. how many bottles of ol
natta225 [31]
Each bottle costs seven dollars. Two of them would cost $14 and three would cost $21. Buying three bottles, the amount is $21 which exceeds $16. Therefore, a $5 discount will be given. Subtracting $5 from the $21 will give $16. You have just enough amount to buy THREE bottles of olive oil.

If −5e^x^2 y=x and y(−5)=0, find y′(−5) by implicit differentiation
xenn [34]
Differentiate:
-5×2(xe^x^2)y-5e^x^2dy/dx=1
-5e^x^2(2xy+y´)=1
When x=-5, y=0:
-5e²⁵y´=1, so y´(-5)=-eˉ²⁵/5
