So firstly, substitute the values into the expression: 
Next, solve the exponents: 
Next, solve the multiplications: 
Lastly, combine everything, and <u>your answer will be -23.</u>
Answer:
x = -10
Step-by-step explanation:
2(x + 1) - 10 = -28
2 * x = 2x
2 * 1 = 2
2x + 2 - 10 = -28
Combine like terms
-10 + 2 = -8
2x - 8 = -28
+8 +8
2x = -20

Answer:

Step-by-step explanation:
We are to find a formula for the general term of the sequence

We are given that
.
- The numerators of these fractions start with 3 and increase by 1. The second term has numerator 4, the third term has numerator 5; in general, the nth term will have numerator 2+n
- The denominators are powers of 5, so
has denominator
- The signs of the terms are alternately positive and negative so we need to multiply by a power of −1. Here we want to start with a positive term and so we use
.
Therefore,

Answer:
-431
Step-by-step explanation:
4-5=-1 -1-5= -6 common difference is -5 and start at 4 to get 88th term which is -431
14 units^2 because you divide the shape into two parts find the area of each shape then add it together
