It cannot be expressed as a mixed fraction. Dividing 36 by 4 gives 9 which is a whole number.
Answer:
2nd and 3rd are polynomials, rest arent
Step-by-step explanation:
Polynomial has to have no ||s, sqrts, or variables in denominator of fraction
-8-n=-6n+12
+8. +8
-n=-6n+20
+6n +6n
5n=20
5. 5
n=4
Answer:
See below in bold.
Step-by-step explanation:
1. The 3 angles in a triangle add up to 180 degrees.
So x = 180 - (55 + 25)
= 180 - 80
= 100 degrees.
2. The 4 angles in a quadrilateral add up to 360 degrees,, so
3x + 127 + 54 + 119 = 360
3x + 300 = 360
3x = 360 - 300
3x = 60
x = 20 degrees.
3. Exterior angle
= 94 + 42
= 136 degrees.
