You would use the Pythagorem Theory which is a^2 + b^2 = c^2
the diagonal being c and it doesn't matter how you substitute tho other either a or b. the answer is 15.588 or 15.6 inches

Answer:
(3) y = (x -3)²
Step-by-step explanation:
Try the first value of x in each function:
(1) y = 3² -3 ≠ 0
(2) y = (3 +3)² ≠ 0
(3) y = (3 -3)² = 0 . . . . . . matches the table value for f(3)
(4) y = 3² +3 ≠ 0

The only viable choice is (3).
If Angie and her friends ate 3/4 of a pizza, that means that 1/4 is left.
Joe ate 2/3 of 1/4 of a pizza. To find out how much he ate, multiply 1/4 by 2/3.
![\frac{1}{4}* \frac{2}{3}= \frac{2}{12}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B4%7D%2A%20%5Cfrac%7B2%7D%7B3%7D%3D%20%5Cfrac%7B2%7D%7B12%7D%20)
because you multiply fractions straight across.
Your answer is 2/12 or
<em>1/6 of the pizza</em>
Answer:
x²+1/x² = 51
Explanation:
Given x - 1/x = 7 ---(1)
We know the algebraic identity:
a²+b²-2ab = (a-b)²
Or
a²+b² = (a-b)²+2ab
Now,
x²+1/x²
= (x-1/x)²+2*x*(1/x)
= (x-1/x)²+2
:7²+2 [ from (1)] =
= 49+2
= 51
Therefore,
x²+1/x² = 51
