Answer:
The box has 6 sides. 2 each of 8 x 9, 8 x 12 and 9 x 12 ie 2 x (72 + 96 + 108) ie 2 x 276 which is 552 sq ins.
Step-by-step explanation:
x=25
Step-by-step explanation:
2000=400√x
Step 1: Flip the equation.
400√x=2000
Step 2: Divide both sides by 400.
400√x/400=2000/400
√x=5
Step 3: Solve Square Root.
√x=5
x=52(Square both sides)
x=25

Answer:
The value of 3 in 46.132 is 10 times the value of 3 in 8.553.
Step-by-step explanation:
The value of 3 in 46.132 is in hundredth's place.
The value of 3 in 8.553 is in thousandths place.
We can write as :
For 46.132, its value is 
and for 8.553 its value is 
.
Taking,
So, the value of 3 in 46.132 is 10 times the value of 3 in 8.553. Hence, the correct answer is A.

Answer:
Answer: 3 1/2 and -10 1/2 are the two numbers.
Step-by-step explanation:
Let x and y be the two unknown numbers.
x+y=-7 [Given]
x-y=14 [Given]
x-y=14 [Given]
x=y+14 [Add y to both sides]
x+y=-7 [Given]
(y+14)+y=-7 [Subtitution]
2y+14=-7 [Combine like terms]
2y=-21 [Subtract 14 from both sides]
y=-21/2 [Divide both sides by 2]
y=-10 1/2 [Division]
x-y=14 [Given]
x=y+14 [Add y to both sides]
x=-10 1/2 + 14 [Substitution]
x= 3 1/2 [Addition]
Check:
x+y=-7 [Given]
3 1/2 + -10 1/2?=-7 [Substition]
-7=-7 [Addition]
QED
x-y=14 [Given]
3 1/2 - -10 1/2?=14 [Substitution]
3 1/2 + 10 1/2?=14 [Change the sign of the subtrahend and add]
14=14 [Addition]
QED
Answer: 3 1/2 and -10 1/2 are the two numbers.
