3 (300000+90000+500000+440)
then just add 10000 to get 2,681,320
3x+8=5x-1
3x-5x=-1-8
-2x=-9
x=4,5
AM=3x4,5+8=21,5
MB=5x4,5-1=21,5
AB=AM+MB
AB=21,5+21,5=43
SA=(L*W*2)+(L*H*2)+(W*H*2)
SA=208+80+130
SA=418
It's 418
Just so you know, it has to be written as a lowercase i to represent an imaginary number.
a) 2i
The square root of 4 is 2, the negative under the square root is what makes it imaginary
b) 2i times the square root of 3
c) 5 + (5i times the square root of 2)
d) 3 - (i times the square root of 2)
