They will be 81 of each kind of animal she will have
P(7,6), Q(1,6), R(4,2)
We have PQ parallel to the x axis. We'll call that the base,
b = 7 - 1 = 6
The altitude is then the y difference h = 6 - 2 = 4
The area is 
Answer: 12 square units
In general we can use the shoelace formula for the area of any polygon given coordinates. We write the points like this:
(7,6), (1,6), (4,2)
(1,6), (4,2), (7,6)
The area is then half the absolute value of the sum of the cross products:

To solve the equation using complete square method we proceed:
z^2-19z=66
but
c=(-b/2a)^2
c=(-19/2)^2
c=361/4
thus:
z^2-19z+361/4=66+361/4
factoring the LHS we get:
1/4(2z-19)^2=625/4
(2z-19)^2=625
getting the square root of both sides we get:
2z-19=+/-25
2z=+/-25+19
2z=44 or -6
z=22 or -3
Answer: z=22 or z=-3
Answer:
19
Step-by-step explanation:
10[4 times 10 divided by (6^2-4^2) +1]
First you would multiply 6 x 6 = 36
10[4 times 10 divided by (36-4^2) +1]
Second you would multiply 4 x 4 = 16
10[4 times 10 divided by (36-16) +1]
Third you would subtract 36 - 16 = 20
10[4 times 10 divided by 20 +1]
Fourth you would add 20 + 1 = 21
10[4 times 10 divided by 21]
Fifth you would multiply 4 x 10 = 40
10[40 divided by 21]
Sixth you would divide 40 divided by 21 = 1.90
10[1.90]
Seventh you would multiply 10 x 1.90 = 19
Your answer would be 19.
