The degree of a polynomial is<span> the highest </span>degree<span> of its terms when the </span>polynomial is<span> expressed in its canonical form consisting of a linear combination of monomials.</span>The degree<span> of a term is the sum of the exponents of the variables that appear in it.</span>
The correct answer is D, 146 inches.
7 x 12 = 84
4 x 12 = 48
84+48+4+10 = 146
<span>2d – e = 7 </span>
<span>d + e = 5 </span>
<span>3d=12 </span>
<span>d=4 </span>
