Answer:
exact form: -7/8
decimal form: -0.875
Step-by-step explanation:
If this is a cube and each side is 6ft, each face will have an area of 6ft * 6ft, or 36ft. There are 6 faces on a cube, so 36ft * 6 = 216ft² as the surface area (it's also the same as 6³, fancy huh?)
Answer:
It might help you if you knew what variable was.
A variable can be (x) or (y) or anything really it just a letter the represents a number.
In this case, when it says solve for a variable it means find what the variable equals. For example:
4x + 18 = 2
here you need to find the value of X.
x = -5
X equals negative 5 because you multiply the variable to the number:
4 x -5 = -20
-20 + 18 = 2
making the answer:
4(-5) + 18 = 2
x = -5

F(a+1)=(a+1)^2+1
=a^2+2a+1+1
=a^2+2a+2
