Answer:
x^2 + 10x - 13y.
Step-by-step explanation:
3(2x + y) + 4(x - 4y) + x^2 First apply the Distributive law to the parentheses:
= 6x + 3y + 4x - 16y + x^2 Now add like terms:
= 10x - 13y + x^2.
Check the picture below.
and since a triangle has a sum of 180° for all interior angles.
A = 180 - 39.34 - 25
A = 115.66

make sure your calculator is in Degree mode.
Answer:
