which expressions are equivalent to 4b? choose all answers that apply: a b + 2(b + 2b) b 3b + b c 2(2b)
Answer
Explanation:
Step1: Simplify option A
$b + 2(b + 2b)=b + 2(3b)=b+6b = 7b$
Step2: Simplify option B
$3b + b=(3 + 1)b=4b$
Step3: Simplify option C
$2(2b)=(2\times2)b = 4b$
Answer:
B. $3b + b$, C. $2(2b)$
