Answer:
a=20 m²
b=21 cm²
c=36 dm²
Step-by-step explanation:
A) 12²+16²=a²
144+256=a²
400=a²
√400=a
a=20
B) 28²+b²=35²
784+b²=1225
b²=1225-784
b²=441
b=√441
b=21
C) c²+15²=39²
c²+225=1521
c²=1296
c=√1296
c=36

Step 1 gives you
3*(4x - 2) on the left hand side.
When you remove the brackets what you get is
3*4x - 3*2
12 x - 6 You have to distribute on both sides of the plus sign. The answer is the second one down.
So the answer is 2) <<<< answer.
LHS=18-3(2p+4)
=18-6p-12
=6-6p
=3(2-2P) hence it is not equal to 3(2-3p)
