Answer:
681 square inches
Step-by-step explanation:
The surface area of a rectangular prism of dimensions L, W, and H is given by ...
A = 2(LW +H(L+W))
The surface area of the given box is ...
A = 2(12·3 +18.25(12 +3)) = 2(36 +273.75) = 619.5 . . . square inches
The amount of wrapping paper required is 10% more than this value, so is ...
paper required = (1 +.10)(619.5) = 681.45 ≈ 681 . . . square inches
Answer:
x=3/8
Step-by-step explanation:
3x+x-3/2=0
4x=3/2
8x=3
x=3/8
check:
3(3/8)+3/8-3/2=
9/8+(3-12)/8=
9/8-9/8=0
(c) 1792
v1+v2
v1=64 v2=1728
64+1728=1792
Answer:
x < 6
Step-by-step explanation:
It has to be a number lower than 6, because 6+6 is 12 and that creates a balanced system.
It cant be a number higher than 6, because it will drag itself down.
So we need a number that when combined, it's sum will be lower than 12
