Answer:
40
Step-by-step explanation:
Let the numbers be 2x and 3x
Then their L.C.M. = 6x
BUT also their LCM=48
6x=48
x=48/6
x=8
So,
First number=2x=2x8=16
Second number=3x=3x8=24
The numbers are 16 and 24.
Hence required sum =(16+24)=40
So none of the options are correct
The solution of the equations is (-2, -1)
<h3>System of equation:</h3>
2x - 3y = -1
11x - 9y = -13
Using elimination method let multiply the first equation by -3.
Therefore,
-6x + 9y = 3
11x - 9y = -13
5x = -10
x = -10 / 5
x = -2
let's find y as follows;
2(-2) - 3y = -1
-4 - 3y = -1
-3y = -1 + 4
-3y = 3
y = 3 / -3
y = -1

Answer:
28 inch
Step-by-step explanation:
The length of all four sides of square is equal.
The formula used for finding the area of square is:
Area = (Length) × (Length)
Thus, the Area of square whose length is 2√7 is:
Area = 2√7 × 2√7
⇒ Area = 4 × 7 = 28 inch.
<em>(7+5) x 6 + 3 = 75
75 is the answer</em>
