<span>(9t-4)(-9t-4)
using the FOIL :
9t * -9t = -81 t^2
9t * -4 = -36 t
-4 * -9t = 36 t
-4 * -4 = 16
-----------------------add up and simplify

Answer: C. I, II, and III only</h3>
Basically everything but statement IV is true
Horizontal lines always have a slope of 0 to indicate no rise is going on.
Vertical lines have undefined slopes which you can see through the slope formula (recall that you cannot divide by zero).
Line 'a' goes through the point (5,0) making statement III true. However, statement IV is false because (-5,0) is not on line b. Line b is parallel to the x axis, so it does not have an x intercept.
Answer:
21, 42, 63, 84
Step-by-step explanation:
3x7=21
Because of this all multiples of 21 will be common multiples of 3 and 7
Step-by-step explanation:
The question needs to be more specific. But assuming it is 0.5y/(4/9), I will solve it.
This would make it 4.5y/4 =y + 3/8
- Multiply 4 to both sides
4.5y = 4y + 12/8
- Subtract 4y to both sides
0.5y = 12/8
- Divide both sides by 0.5
y = 3
Now plug in to check.
0.5(3)/(4/9)=3+3/8
Both equals 3.375!
If this helped, please feel free to pick this answer as the brainliest! Thank you very much and have a wonderful day!
C is 0.003 and so is a and so is b
