===================================
The first equation is
4x + 2x²(3x-5) = 4x + 6x³ - 10x² = 6x³ - 10x² + 4x
So, The degree of the function = 3 , and the number of terms = 3
============================================================
The second equation is
(-3x⁴ + 5x³ - 12 ) + ( 7x³ - x⁵ + 6 ) = -x⁵ -3x⁴ +12x³ - 6
So, The degree of the function = 5 , and the number of terms = 4
============================================================
The third equation is
(3x² - 3)( 3x² + 3) = 9x⁴ - 9
So, The degree of the function = 4 , and the number of terms = 2
6(x + 15 ) = -42
6(x + 15) = -42
6x + 90 = -42
x = -132/6= -22
Answer:
x = 98°
Step-by-step explanation:
We know that in a heptagon, there are 900°. <em>So</em>,
900 - (146 + 122 + 142 + 140 + 110 + 142)
We plug that into the calc and we should get 98 as our final answer!
