The exact value of tan A is 1
Refer to the attached file for the explanation
Answer:
Step-by-step explanation:
1)It should be (-4)
2) It should be (-6) Not (-2)
3) It should be 30x²
4) It should be xyz
5) It should be 
6) 16x²
7) 
8) 
9)
10) a² + b² +2ab
11) -9
12)x² - x + 0
yes the equation can be used to measure density
-(9x+12)=-8x-(x+3)
-9x-12= -8x-x-3
-9x+9x=9
-9
if u look at the eq for x it has no value. but if u r asking a solution for a eq then it is -9
That's strange. (3)(415) isn't exactly done with distributive property.
But let's try this:
3(415)
= 3(400+15)
= 1200 + 45
= 1245
So it's just breaking down the numbers...
But the answer is actually 1245.
