Answer:
option 3
both (3, 2) and (2, -1) are solutions
For this, we need to find the lowest common multiple of 10 and 8
multiples of 10 : 10,20,30,40,50
multiples of 8 : 8,16,24,32,40
so the LCM of 10 and 8 is 40
therefore, they will both flash at the same time again in 40 seconds.
Step-by-step explanation:
set that width is x
and length become 2X
P = 2×( X+ 2X )
200 = 6 X
X=33. 3
width = 33.3 inch
length = 66. 6 inch
So find the volume of the separate shapes. For rectangular prisms (which includes cubes), multiply width by height by length. So multiply 4 by 6 by 2. And for the cube, multiply 2 by 2 by 2. Then, to find the total volume, add the two together.
