Answer:
8a - 7
Step-by-step explanation:
First, subtract 12a from 20a
20a - 12a
= 8a
Now, subtract -3 from -10.
Subtracting a negative number is the same as adding a positive number, so add 3 to -10.
-10 + 3
= -7
Put together 8a and -7
8a - 7
So, the simplified expression is 8a - 7
Your y-intercept would be (0,-15) and your x-intercept would be (-60,0)

Answer:
319 in²
Step-by-step explanation:
The applicable area formula is ...
A = 1/2(g)(e)·sin(F)
A = 1/2·(12 in)(55 in)sin(75°) ≈ 319 in²
The area of the triangle is about 319 square inches.
