Step-by-step explanation:
substitute for y
x+3+4 = -6x
x+ 7 = -6x
7 = -7x
-1 = x
y = -1+3
y = 2
Larger by 3 means that the legnths of the sides are larger by 3 times
so we have a cube that has area of 400
surface area=legnth times width times 6 since it is a cube and legnth=width
so
SA=w^2 times 6
6w^2=400
divide by 6
w^2=200/3
square root both sides
w=√(200/3)
so w is 3 times larger
(3w)^2 times 6 is new area
w=√(200/3)
(3√(200/3))^2 times 6=9(200/3) times 6=600 times 6=3600
answer is 3600 ml^2
3,751+3,751= 7,502
3,75l*2=7,502
15,004/2= 7,502
5,689+1,831=7,502
8,965-1,463=7,502
62*121=7,502
31*242=7,502
11*682=7,502
7,000+502=7,502
7,000+400+102=7,502
6,000+1,500+2
