Answer: D. -3.2
Step-by-step explanation:
The correct answer to this question is D. -3.2 because when you subtract positive 8.8 and positive 12 your answer is -3.2.
(+8.8) - (+12) = -3.2
1/6 of an hour is 10 minutes because there are 60 minutes in an hour so 60/6=10
so it's 25m^2/10minutes
now just multiply 25 by 12 ( 12 lots of 10 minutes in 2 hours)
25*12=300
answer is 300m^2

Answer:
6a + 1
Step-by-step explanation:
First, you need to multiply everything in the brackets by 3L
(7 + 2a) x 3 =
7 * 3 = 21
2a * 3 = 6a
21 + 6a
Now you can subtract the 20 from this:
6a + 21 - 20
Simplified down:
6a + 1

The two numbers are illustrations of system of equations
The two numbers are 2.7 and 37.3
<h3>How to determine the two numbers?</h3>
Let the numbers be x and y.
So, we have the following equations
x + y = 40
xy = 100
To determine the value of the variables, we simply plot the graph of both equations
From the graph, we have the following result
(x,y) = (2.7, 37.3)
Hence, the two numbers are 2.7 and 37.3

P = 11 + 4 + 18 + 37 + 7 + 19 = 96
a = (18*7) + (11*19) = 126 + 209 = 335
