Answer:
20 miles
Step-by-step explanation:
I'm not sure if that is exactly how you solve it but
If its
8x+4 as the equation and x is the number of hours run
the total number of miles run should be 20 miles
8(2)+4=20
Pounds is more if you do the math
Answer:
C
Step-by-step explanation:
Answer:
L = 20 inches
Step-by-step explanation:
w = width
L = length
area = 120
W x L = 120
L - 8 = 2W then L = 2W + 8
substitute for L:
W x (2W + 8) = 120
2W² + 8W -120 = 0
(2W - 12)(W + 10) = 0
2W-12 = 0
2W = 12
W = 6
L = 20
The answer is <span>C.) 2
The general form of formula is
y = a </span><span>• r^x
y - the total number of bacteria after x period of time
a - the initial number of bacteria
r - growth rate
x - period of time
Let's compare:
</span>y = a • r^x
<span>y = 280 • 2^x
Since r = 2, the growth rate is C.) 2</span>
