Help me please FAST Norman is replacing his wooden deck that measures
11 1/2
feet by
8 1/2
feet. He wants to increase both the length and width of the deck floor by 2 feet. The wood costs $4.25 per square foot. To the nearest cent, how much will the wood for the new deck floor cost?

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:

b. 18

step-by-step explanation:

so the equation for this is:

ab^2=ac⋅ad

ab being the top length of 6 and ac being the length of 2 and ad being the length of x. let's plug into the equation:

6^2 = 2x

now lets just solve for x:

36 = 2x

18 = x

i hope that !

you'll have to attache the image of the bar graph in order for us to answer : )
