Answer:
The answer is 6
Step-by-step explanation:
b(x) = |x+4|
b(-10) = |-10+4|
= |-6| (absolute value is always interested in +ve value)
= 6
2*27= 54 which is an even number, not a perfect square, odd or prime. The prime factorization would be 2*3^3
B, Even

now, notice, we use the decimal format for the percent, namely 17% is 17/100 or 0.17 and so on
so.... we know, whatever "x" and "y" is, they must add up to 100 grams
thus x + y = 100
and whatever the concentrated amount is, it must add up to 17 grams for the composition
thus 0.1x + 0.2y = 17

solve for "x", to see how much is needed of the 10% alloy
what about "y"? well, y = 100 - x
