Answer:The answer is D -10x+ 1.5

Step-by-step explanation:Because if you use the distributive property on

-2(5x - 0.5) you multiply -2 by 5x to get -10x then you multiply -2 by -0.5 to get a positive 1.5.

When p2 – 4p is subtracted from p2 + p – 6, the result is 5p-6 To get p – 9, subtract
jeka57 [31]
(p^{2}  + p - 6) - (x) = p - 9

 is what is asked.

So all you need to do is a value that will result to p - 9.

x = (p^{2} + p - 6) - p + 9  To isolate x we just transpose the values from the other side of the equation and do the opposite operation. 

Combine like terms and just copy the terms that do not have similar expressions:

p will cancel out because p - p = 0
-6 and + 9  will come together because they are like terms: -6 + 9 = 3 
p^{2} does not have a pair so it will remain as is. you will be left with:

p^{2}  + 3

Let us check:

   p^{2} + p - 6
-  p^{2} + 0 + 3  
----------------------------
   0 + p - 9    or p -9

Answer:

h) (x+4t²)/4= 3V

x+4t²= 4*3V

x+4t²=12V

x=12V-4t²

MN=√(3x-2)

(MN)²=3x-2

3x-2=(MN)²

3x=(MN)²+2

x= [(MN)²+2]/3
