Answer:
$16
Step-by-step explanation 2 x 8 to 8 + 8 =16
The sum can be rewritten as y=4x, where y=f(x).
Now, we can rewrite the equation a x=y/4
Therefore, inv(f(x))=x/4
We use the law of Cosines to find b=AC opposite B
We know all the sides of triangle ABM so we can use the law of Cosines, this time to solve for
Substituting,
Answer: AC=√39
39 has factors (1 * 39) & (3 * 13)
Here we'll try
m + n = 13
m - n = 3
2m = 16
m = 8
2n = 10
n = 5
2mn = 2 * 8 * 5 = 80
So this choice is no good.
Let's go with
m + n = 39
m - n = 1
2m = 40
m = 20
2n = 38
n = 19
Thus
x = 20² - 19² = 39
y = 2 * 20 * 19 = 760
z = 20² + 19² = 761
