5x^2 +10

Step-by-step explanation:

The area is the product of height and width:

A = (height)(width) = (5)(x^2 +2)

A = 5x^2 +10

By the fundamental theorem of calculus,

$E(t)=E(1)+\displaystyle\int_1^t E'(u)\,\mathrm du$

So we have

$E(t)=92+\displaystyle\int_1^t(75-6u)\,\mathrm du$

$E(t)=92+(75u-3u^2)\bigg|_1^t$

E(t)=20 + 75 t - 3 t^2
