For Question Number one
(2+10)²+4=148
Question Number two:
(6+5)×(8-6)=22
Answer:

Step-by-step explanation:
The relationship between A, the area of the glacier in square kilometers, and t, the number of years the glacier has been melting, is modeled by the equation.:

We want to determine the value of t for which the area, A(t)=15 square kilometers.

Therefore, the time for which the area will be 15 sqyare kilometers is:
-20 ln(1/3) years.
Slope = (-2 + 4)/(-2-2) = 2/-4 = -1/2
y = mx + b
so
b = y - mx
b = -2 -(-1/2)(-2)
b = -2 - 1
b = - 3
equation
y = -1/2x - 3
answer is B.
y = -1/2x - 3
When you do the second step it is 40 so you add one zero from the 7200 and thats where you got the zero
