Guys plsss i need help. It needs work too
Ghella [55]

Answer:

f(x+h)=x^2+2xh+h^2+2x+2h

Option D is correct option.

Step-by-step explanation:

We are given: f(x)=x^2+2x

We need to find f(x+h)

For finding f(x+h) we need to replace x by x+h

f(x+h)=(x+h)^2+2(x+h)\\We \ know \ (a+b)^2=a^2+2ab+b^2\\f(x+h)=x^2+2xh+h^2+2x+2h

Finding f(x+h) we get:

f(x+h)=x^2+2xh+h^2+2x+2h

Option D is correct option.

I need help remembering the steps to solve a polynomial equation
murzikaleks [220]
Example 1 – Solve: 3x3 = 12x

Step 1: Write the equation in the correct form. In this case, we need to set the equation equal to zero with the terms written in descending order.

 3x^3-12=0

Step 2: Use a factoring strategies to factor the problem.

 3x(x^2-4)=0
3x(x+2)(x-2)=0

Step 3: Use the Zero Product Property and set each factor containing a variable equal to zero.

 3x=0 or x+2=0 or x-2=0

Step 4: Solve each factor that was set equal to zero by getting the x on one side and the answer on the other side.

 x=0 or x=-2 or x=


I hope this helped you!

Saeed bought 21 1/2 lb. of ground beef. He used 1/4 of the beef to make tacos and 2/3 of the remainder to make quarter-pound bur
blagie [28]
This may be a little complicated, but basically, you have to break everything down into decimals. 21.5 X .25 = 5.375. Subtract 5.375 from 21.5 and you should get 10.75 or 10 3/4. Divide 10 3/4 by 1/4, the answer should be 30 burgers.
