Answer:
-45
Step-by-step explanation:
-50 + 2a represents the sum of the constant -50 and twice the value of the variable a.
If a = 2.5, then -50 + 2a has the value -50 + 2(2.5) = - 50 + 5 = -45.
The formula for the number of divisors (d) is
d = (m+1)(n+1)
where this number includes the values 1 and p^m*q^n
_____
This can be generalized to more or fewer prime factors. Add 1 to each of the exponents and form the product of those values.
Answer:
d = 4
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
Step 2: Subtract 2d from both sides.
Step 3: Add 24 to both sides.
Step 4: Divide both sides by 10.
Therefore, d = 4! I hope this helped you.
