Writing a polynomial expression to represent perimeter
a family needs to build fencing around their rectangular
home and square swimming pool, depicted below.
the total amount of fencing they need can be written
as i fx + 10.
pool (2x) yd
if x = 5
the family needs
their home
yards of fencing for
yards of fencing for their
home
(2 + 5x) yd
the family needs
pool
(3 + 10x) yd

step-by-step explanation: a reaction is first order. if the initial reactant concentration is 0.0200 m, and 25.0 days later the concentration is 6.25 x 10-4 m, then its half-life is:

im not sure

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
