If you want to solve this problem using formulas, there are two important formulas:
t1 = first term = -5
tn = nth term = last term = -5
n = numbr of terms
Sn = sum of the n terms
tn = t1 + (n - 1)d ---> 65 = -5 + (n - 1)(5)
65 = -5 + 5n - 5
65 = -10 + 5n
75 = 5n
n = 15
Sn = n(t1 + tn)/2 ---> Sn = 15(-5 + 65)/2
Sn = 450
So ur answer rounds up to 450

Answer:

Step-by-step explanation:
you just add
The correct answer is 4x to the third power.
A decimal is a number, not under the form of a fraction, neither as a whole number, but a number that contains a decimal point. Each fraction got a value under the form of either w whole number, either a decimal number.
You could easily use a calculator to get the value of 4/3:
4/3 ≈ 1.33 (The decimal point is easily seen between 1 and 3)
