Answer:

h(x) = 4(x+\frac{1}{2})^{2}

Step-by-step explanation:

h(x)=4x^2+4x+1\\h(x)=4(x^2+x+\frac{1}{4}) \\h(x)=4(x^2+x+\frac{1}{4})\\h(x) = 4(x+\frac{1}{2})^{2}

Two sides of an isosceles triangle have lengths of 4 and 8. What is the length of the third side?
Gnoma [55]

Answer:

8

Step-by-step explanation:

Let's start with a simple fact: two sides of an isosceles triangle must be equal. Let's suppose the missing side is 4

That would mean that 4 + 4 equals 8. You must pick a side that exceeds 8, but you loose the property of 2 sides need to be equal.

So the answer has to be 8. The final size of the sides is 4 8 and 8. 4 and 8 exceed the third side (8).

8 and 8 certainly exceed 4.

Given the following chemical reaction:
Marizza181 [45]

Answer:

The answer to your question is 12 moles of water.

Step-by-step explanation:

Reaction

                            2 O₂   +   CH₄     ⇒     CO₂    +   2 H₂O

If Oxygen is in excess, then the limiting reactant is methane and we calculate the moles of water produced considering the moles of methane.

                          1 mol of methane --------------  2 moles of water

                           6 moles of methane ---------   x

                           x = (6 x 2) / 1

                           x = 12 moles of water
