Answer:
4a²-9
Step-by-step explanation:
(2a+3)(2a-3) = (2a)²-3² {<em>Difference</em><em> </em><em>of</em><em> </em><em>two</em><em> </em><em>squares</em><em>}</em>
= 4a²-9
1st day he ran30. 2nd day he ran 35 3rd day he ran 35 and fourth day he ran 45 so 30+35+35+45 =145 minutes all together he ran
At the end of the third day, the new reading on the odometer will be 12,578 mi
<h3>
What will the odometer reading at the end of the third day?</h3>
The initial odometer reading is 12,386 miles.
Then, the driver takes drives to and from work, such that each trip is 32 miles. Then each day he drives 2*2mi = 64 miles.
And he does this for 3 days, then the total distance driven is:
3*64mi = 192 miles.
At the end of the third day, the new reading on the odometer will be:
R = 12,386 mi + 192mi = 12,578 mi

Trapezoid Area =
[ ( Sum of the rules ) × ( height ) ] ÷ 2
_________________________________
Area = [ ( 6 + 12 ) × 8 ] ÷ 2
Area = [ 18 × 8 ] ÷ 2
Area = ( 18/2 ) × 8
Area = 9 × 8
Area = 72
