It is given that a+b=6 and ab=7. Find the value of a^2 + b^2.
n200080 [17]
Use the identity:-

a^2 + b^2  = (a + b)^2 - 2ab

Plugging in the given values;-

a^2 + b^2 = 6^2 - 2*7    =  36-14  = 22 Answer

Khianna wants to make a batch of her Grandma chocolate chip cookies from a friend. The recipe is shown on the recipe card below
romanna [79]
Poor <span>Khianna.  Let's help her out.

For the original recipe she needs </span>1 \frac 1 2 = \frac 3 2 cups of brown sugar but only has 1 \frac 1 8 = \frac 9 8 .  So the fraction of the brown sugar she has is

\dfrac{ \frac{9}{8} }{\frac 3 2} = \frac 9 8 \times \frac 2 3 = \frac 3 4

She has to scale everything by a factor of  \frac 3 4

I won't multiply everything by 3/4 for you.  2 cups butter becomes 1 and a half cups butter, 1 tsp vanilla becomes 3/4 tsp, etc.

Masja [62]

Answer:

The second one; x²+7x+12

Step-by-step explanation:

So, since the beginning lengths of the square is x and x, the area of the square is x².

But then, you add 3 to one length, so that side is now (x+3), and then you add 4 to the width, so that is now (x+4).

Finally, you would multiply them together to get the equation you would use to find the new area.

For this, you would cross-multiply everything together; the x in the length by the x in the width, the x in the length by the 4 in the width, the 3 in the length by the x in the width, and then the 3 in the length by the 4 in the width. Now, all you have to do is add all of these together to get your answer.

Here's the work:

(x+3)(x+4)\\x^{2}+3x+4x+12\\x^{2}+7x+12
