Answer:
x = 98
Step-by-step explanation:
The sum of the interior angles in a polygon is
sum = 180° (n - 2) ← n is the number of sides
here n = 7, thus
sum = 180° × 5 = 900°
Sum the interior angles and equate to 900
x + 146 + 122 + 142 + 140 + 110 + 142 = 900, that is
x + 802 = 900 ( subtract 802 from both sides )
x = 98
FOIL and PEMDAS are both ways to solve mathematical equations.
<u>FOIL</u><u />
First
Outside
Inside
Last
<u>PEMDAS
</u>Parenthesis
Exponents
Multiplication &
Division
Addition &
S<u />ubtraction
FOIL is usually used to solve equations in two sets of parenthesis, for example:
(23+x)(5-4x)
PEMDAS is used to solve multiple-operation equations, such as:
5 x 4 + 6 - 2 x 7

Answer:
6x⁴ + 6x³ + 2x² + 4
General Formulas and Concepts:
<u>Algebra I</u>
Step-by-step explanation:
<u>Step 1: Define</u>
(6x³ - x⁴ + 7) + (7x⁴ - 3 + 2x²)
<u>Step 2: Simplify</u>
- Combine like terms (x⁴): 6x⁴ + 6x³ + 2x² + 7 - 3
- Combine like terms (Z): 6x⁴ + 6x³ + 2x² + 4
