answer: 1
Answer:
3.6
Step-by-step explanation:
Pythagorean theorem:
a^2 + b^2 = c^2
(6 km)^2 + b^2 = (7 km)^2
36 + b^2 = 49
b^2 = 13
b = sqrt(13)
b = 3.6
Answer: 3.6 km
The fish market sell 16 pound of fish and 12.5 pound of lobster.
This is a perfect square trnomial
(a+b)²=a²+2ab+b²
we see that a=5x and b=2
(5x)²+2(5x)(2)+2²=0
factor
(5x+2)²=0
set equal to zero
5x+2=0
5x=-2
x=-2/5
27 is 6
29 is 70
31 is 60
those are all of the answers.
