Answer:
a)a^4 + 19a^2 -12ab - 3b^4 +6b...
Answer:
Option A will be correct.
Step-by-step explanation:
Here in this problem we have to get the simplified expression of
.
Now, 
= 
{Using the Distributive Property of multiplication which gives, a(b + c) = ab + ac}
= 
= - (2)(5)x - 24
= - 10x - 24 (Answer)
Therefore, option A will be correct. (Answer)
Answer:
m=42
Step-by-step explanation:
because all straight line equal 180, we can find angle C
180-98=82
now, all triangles add up to 180. If we add up all the values we can find x
82+6x+8+5x+2=180
92+11x=180
11x=88
x=8
Now, just plug the variable into the angle measure
5(8)+2
40+2
42
