Answer:
The coefficient is 1
Step-by-step explanation:
There is an imaginary 1 in front of variables that becomes the coefficient if there isn't already a number there. If it was 5x squared, the coefficient would be 5.

Answer:
D!
Step-by-step explanation:
Answer: 29.2cm
Step-by-step explanation: perimeter of parallelogram; 2(a + b) where a = base, b = altitude
a = 8cm
b = 6.6cm
Perimeter = 2(8 + 6.6) = 2(14.6)
Perimeter = 29.2cm
The equation is:
20,000 * e^(0.15 t) = 28,000
e^( 0.15 t ) = 28,000 : 20,000
e^( 0.15 t ) = 1.4
0.15 t = ln 1.4
0.15 t = 0.3365
t = 0.3365 : 0.15
t = 2.24 ≈ 2
