Answer:
C: Square centimeters
Step-by-step explanation:
We are measuring length here, not volume, so recognize that this fact eliminates Answer B. The area of a rectangle, such as this picture is, is A = Length * Width, measured in (cm)(cm), or C: Square centimeters.
Answer:
2(2x + 1)
Step-by-step explanation:
4x = 2 * 2x
2 = 2 * 1
20 + 30 = 50 people in total
So in the 30 ,10 people were pranked and 10 did not, that means the other 10 people did not even listen to them or something.
But it is for sure that there are 50 people in total over there.
We know that
12²--------> (2²*3)²------> 16*9-----------> 144
20²-18²-----> (2²*5)²-(2*3²)²-----> 16*25-4*81--------> 400-324------> 76
8(4^2)+2^4---------> 2³*(4²)+2²*2²-------> 2³*(2²*2²)+2²*2²----> 128+16----> 144
15²-3^4------> (3*5)²-(3²*3²)------> 9*25-9*9------> 225-81-------> 144
the answers are
