B). It looks as though they factored it.
Answer:
$18.96
Step-by-step explanation:
Multiply 24 by 0.15= 3.6
Multiply 24 by 0.06= 1.44
Add 3.6 and 1.44= 5.04
Subtract 5.04 from 24= $18.96
If x is the first number, x+2 is the next consecutive even integer. The difference (subtraction) of their squares equals 20. Therefore:
(x+2)²-x²=20...expand this:
x²+4x+4-x²=20
x²+4x+4-x²=20
4x+4=20
4x=16
x=4. Therefore the next consecutive even integer is x+2=6.
To check: 6²-4² must equal 20
36-16=20 check!
