That's actually pretty easy so since a cube has 6 faces and all the sides are equal you just have to multiply 12x12 whic equals 144 times 6 which is 864
so 864mm to the second power
Answer:
81
Step-by-step explanation:
We need to know the sides of the square so 36÷4=9
Area of a square = Side x side
Area of square = 9x9=81
Answer:
P = 8.5 x + 3 ft
Step-by-step explanation:
To find the perimeter, we use the formula
P =2(l+w) where l is the length and w is the width
P =2 (1.25x+3 + 3x-1.5)
Combine like terms
P = 2( 4.25x +1.5)
Distribute the 2
P = 8.5 x + 3 ft
The missing property is : x=24 Addition Property of Equality
Step-by-step explanation:
We need to identify the missing justification.
Step Justification
negative four plus one fourth times x equals two Given
−16 + x = 8 Multiplication Property of Equality
x=24 ------------
Solving:
-4+1/4x=2 (given)
Multiply both sides by 4
-16+x=8 (Multiplication Property of Equality)
Add 16 on both sides of equation
-16+x+16=8+16
x=24 (Addition Property of Equality)
So, the missing property is : x=24 Addition Property of Equality
