Step-by-step explanation:
-3(2x-1)^2+12x^2
= -3[(2x-1)(2x-1)]+12x^2
=-3[2x(2x-1)-1(2x-1)]+12x^2
=-3(4x^2-2x-2x+1)+12x^2
=-3(4x^2-4x+1)+12x^2
=-12x^2+12x-3+12x^2
=(-12x^2+12x^2) +12x-3
=0+12x-3
=12x-3

➷ Find the cost per pen by dividing:
300/10 = 30
It costs rs 30 for one pen
1 dozen = 12
2 dozens = 24
Multiply the values:
24 x 30 = 720
The cost of 2 dozen pens is rs 720
However, as it is asking for 'how much more' you have to subtract:
720 - 300 = 420
The cost is rs 420 more

Answer:
14 -2i
Step-by-step explanation:
9 + sqrt(-4) - ( -5 + sqrt(-16))
We know the sqrt of a negative number is i * sqrt(number)
9 + isqrt(4) - ( -5 + isqrt(16))
9 + 2i - (-5 + 4i)
Distribute the negative sign
9+2i +5 -4i
Combine like terms
14 -2i
Answer:
empty spaces in order from left to right are 16,12,42
Step-by-step explanation:
because your adding one to the 5 so you add one to the 15 then your × by 12 bc 3×12 is 36 and × by 12 on the top so 6×12 then last one ur adding 6 because 12+6 is 18 and what ever you do to the top or bottom you do the the bottom or top
