This changed the way cities are because cities are usually built to accommodate highways and roads. Built in and around highways have changed the main structure of present-day cities.

(1) The integral is straightforward; <em>x</em> ranges between two constants, and <em>y</em> ranges between two functions of <em>x</em> that don't intersect.
(2) First find where the two curves intersect:
<em>y</em> ² - 4 = -3<em>y</em>
<em>y</em> ² + 3<em>y</em> - 4 = 0
(<em>y</em> + 4) (<em>y</em> - 1) = 0
<em>y</em> = -4, <em>y</em> = 1 → <em>x</em> = 12, <em>x</em> = -3
That is, they intersect at the points (-3, 1) and (12, -4). Since <em>x</em> ranges between two explicit functions of <em>y</em>, you can capture the area with one integral if you integrate with respect to <em>x</em> first:
(3) No special tricks here, <em>x</em> is again bounded between two constants and <em>y</em> between two explicit functions of <em>x</em>.
Answer:
oil produces CO2
coal produces CO2
uranium does not produce CO2 aka nuclear reactors as this process requires dipping the uranium rods into water creating steam and turning a turbine making energy
natural gas does create CO2 but less than coal and oil that is why natural gas is preferred as a energy source
