Every day, it increases by 8 inches. We know that it started at 16 inches.
We can construct an equation with this information.
Equation: 16+8x=h
h=Height
x=Days
Plug in 12 for x:
16+96=h
h=112 inches
Answer: The plant will be 112 inches tall in 12 days.
the formula for volume of sphere is 4/3||r^3
diameter=2radius
in the formula we need to have radius but we have been given diameter so we convert diameter to radius
d=2r
r=d/2
9.5÷2
4.75
They give us the length of side of the square which is 3-7x.
To get an expression for the perimeter that is expressed as a product we have to multiply the expression 3-7x by four since every square has four sides. This will give us an expression of 4(3-7x). We than can use the distributive property to multiply everything inside the parenthesis by 4. This will give us an expression of 12-28x.
