N=-55 -n=11x5 -n= 55 n=-55
(multiply both sides by -1)
Answer:
<u>Useful for this exercise:</u>
- Sum of interior angles of a triangle is 180°
- Straight angle is 180°
- Angle addition postulate
<u>Finding missing angles:</u>
- m∠1 = 180° - (57° + 72°) = 51°
- m∠2 = 90° - 72° = 18°
- m∠3 = 180° - 57° = 123°
- m∠4 = 180° - (18° + 123°) = 39°
Answer:
12 x^4 y^4
Step-by-step explanation:
4x(3x^3y^4)
Distribute
4 (3) *x*x^3 y^4)
Remember a^b* a^c = a^(b+c)
12 x^(1+3) y^4
12 x^4 y^4
The expression given is
The sum of the expression will be,
The sum will be
