Answer:

Step-by-step explanation:
=
=

The sample correlation coefficient r is equal to 0.9962
<span>The linear correlation coefficient is positive. -1 </span>≤ r ≤ + 1.
0.9962 is nearer to +1. Thus, the linear correlation is positive.
Pls. see attachment.
Use quadratic formula
if you had ax^2+bx+c=0, then
x=

a=1
b=?
c=34
subsitute

=5+/-3i

=5+/-3i
make 5+/-3 into fraction over 2,(10+/-6i)/2

=(10+/-6i)/2
multiply both sides by 2

=10+/-6i
we conclude that -b=10
b=-10
ok so equaton is
x^2-10x+34
If the width is 3 on each side, that is 3 + 3 = 6.
26 - 6 = 20.
There are two sides left: 20 divided by 2 = 10.
10+10+3+3 = 26.
The length is 10.
