The answer is 3.....
2x+5
2x3+5=11 2x3=6
4x-1
4x3-1=11 4x3=12
-31 because if you do p.e.m.d .a .s
Answer:
First, you write an explicit formula then plug in the value of n in the formula with the term number you are trying to find, in this case the 13th term.
The steps are in the pictures

- Sum of Angles in a Quadrilateral: 360
Step-by-step explanation:
<u>Step 1: Set up</u>
75 + 120 + 90 + ∠4 = 360
<u>Step 2: Solve</u>
- Add: 285 + ∠4 = 360
- [Subtraction Property of Equality] Subtract 285 on both sides: ∠4 = 75
Answer:
x =4
Step-by-step explanation:
2/3(x-7)= -2
Multiply each side by 3/2 to clear the fractions
3/2 * 2/3(x-7)= -2 *3/2
x-7 = -3
Add 7 to each side
x-7+7 = -3+7
x =4
