Your neighbor is putting a small square deck with side length x+4 as pictured below, where x is measured in feet. Write a polynomial in standard form that represents the area of the deck. Write an expression for the cost of the lumber for the top of the deck if the lumber costs $5 per square foot. If x=3 feet, what will be the cost of the lumber for the top of the deck? ​

answer: 32.68

step-by-step explanation:

x=2

-2/

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25
