Answer: 1, 4, -7
Step-by-step explanation:
Coefficients are numbers that are in front of a variable. Let's first determine the terms that have variables in them.
z, 4z², -7a
Since these all have variables in the terms, we know the coefficients are 1, 4, -7.
area = l x w
w = area : l
w = 5.612 x 10¹⁴ : 9.2 x 10⁷
w = 6.1 x 10⁶
the perimeter: 2(l+w)
= 2(9.2 x 10⁷ + 6.1 x 10⁶)
=1.84 x 10⁸ + 1.22 x 10⁷
=10⁷(18.4+1.22)
= 1.962 x 10⁸ cm
