solution
Mean of two smallest number (3+5 =8/2) =4
Mean of all the three (3+5+19 =27) 27/3 = 9
so the mean of two largest number is 19+5 = 24 /2 = 12
Final Answer
The mean of two largest Number is 12
Answer:
The answer to your question is letter D
Step-by-step explanation:
Data
slope = m = 2
Point (-3, 4)
Process
1.- Substitute the data in the line equation
y - y1 = m(x - x1)
y - 4 = 2 (x + 3)
2.- Expand
y - 4 = 2x + 6
3.- Solve for y and simplify
y = 2x + 6 + 4
y = 2x + 10

Step-by-step explanation:
Required
Determine which option answers the question, correctly.
From the list of given options, only option c answers the question correctly.
This is shown below.
Represent
Length with l and Width with w, such that:

Area (A) is calculated as thus:

Substitute 7 + w for l and 18 for A.
This gives:

Open Bracket

Reorder

Subtract 18 from both sides


See that the above expression is a quadratic equation.
