Answer:
I am pretty sure it is D.
Step-by-step explanation:
Town A is semetrical, meaning that if you fold it exactly in half it would match up. Town B. Is positively skewed, meaning that there is one or more point(s) to the right. (Negatively skewed means the same thing, but to the left instead of the right)
Miguel would have to color one section blue, one section red, and two sections green.
Step-by-step explanation:
length = width + 4
length×width = 77
using the first in the second equation
(width + 4)×width = 77
width² + 4width = 77
now, what square or squaring factors can create this ?
we are looking for (width + a)(width + b).
we know, this is
width² + (a+b)width + ab
so, what a, b can create 4 (the factor in our actual equation) ?
1, 3 and 2, 2, if we are only looking at whole numbers.
and which of the possibilities can we use to turn 77 into a square number ?
81 is only 4 away ...
2+2 = 4.
aha !
so, we can actually say our equation is
width² + 4width + 4 = 77 + 4
and then
(width + 2)² = 81
width + 2 = 9
width = 7 m
length = width + 4 = 7 + 4 = 11 m
2.8x10^-5 ; 2.8x10^-3 ; 2.8 ; 2.8x10^2 ; 2.8x10^4
Multiply 8 by 4 and that will give you 32 then add 9 and you get 41 so the answer is 41 years old
