(PLEASE ANSWER THIS AS SOON AS POSSIBLE! I WILL GIVE 30 POINTS! Involves Polynomials.) When building a square-shaped outdoor fireplace, the ground needs to be replaced with stone for an additional two feet on each side. Write a polynomial for the area that needs to be excavated to create an x by x fireplace.

Design your ideal space for sitting around a fire pit and relaxing. Add furniture, flowerbeds, rock gardens, and any other desired features.

Evaluate the polynomial for the size fireplace you are including.

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.

answer: 94

step-by-step explanation: 79+91+92+94+94 = 450 divided by 5 (since there are 5 number that are being added) = 90

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
