Expression A,B and C are shown below
1 answer:
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
<span>8(4^2)+2^4.
15^2-3^4</span>

Answer:
perimeter = 42 units
Step-by-step explanation:
The answers b because 3/5 of 95 is 57 and 57 plus 12 equals 69
- tan (<Q)=11/8
- m(<Q)=tan^-1(11/8)=53.96°
- tan(<P)=8/11
- m(<P)=tan^-1(8/11)=36.02°
- QP=Square root of (8)^2+(11)^2=square root 185
- the answer of the second question is 53°
5-(6-15)*(3-7)
=5-(-10)(-4)
=5-(40)
=-35
