V = by
Solve for b.
Divide both sides by y to isolate b.
b=
-452°F < 212°F
A negative number is always less than a positive number.
Well, let's write it out, shall we?
6c2-5d+8
Now plug in the numbers.
6(5^2)2-5(4)+8
Now simplify using PEMDAS
Parentheses
Exponents
Multiplication
Division
Addition and Subtraction (They go together go from left to right in the equation)
5^2= 5*5 = 25
6 * 25 = 150
150 * 2 = 300
5 * 4 = 20
Rewrite the equation.
150-20+8
Use PEMDAS again ( refer to the previous mentioning)
150 - 20 = 130
130 + 8 = 138
Answer:
B. 
Step-by-step explanation:
Given expression is 
Simplifying the expression now
Lets use distributive property of multiplication to solve it.
As given, 
Distributing -6 with b and 2.
= 
Opening the parenthesis
= 
= 
∴ As from the given options,
is the correct choice.
