Answer:
<h3>The answer is 7/12.</h3>
Step-by-step explanation:

Solve the terms in the bracket first
That's find the LCM of the ones which are subtracting
LCM of 3 and 4 is 12
That's

Next multiply the other terms in the other bracket
That's

Add both results
That's

Find the LCM
The LCM is 12
We get the final answer as

Answer:
84.85cm
Step-by-step explanation:
Let the sides of the square be x
The perimeter of the square = 4x
Get x using the pythagoras theorem
x^2 + x^2 = 30^2
2x^2 = 900
x^2 = 450
x = 21.21cm
Perimeter of the plate = 4(21.21)
Perimeter of the plate = 84.85cm
A' = (-2, 1)
B' = (1, 0)
C' = (-1, 0)
To find the volume, you do area multiplied by thickness( or height)
In this example, you do (1/2*9*6)*10 which is 270
