C=√a²+b. square both sides
c²=a²+b². subtract a² from both sides
c²-a² = b². take the square root of both sides
b=±√c²-a²
but since length can never be negative we consider only the positive root
b=√c²- a²
The answer is 145 because 145 + 5 is 150 then divided by 2 is 75
1/3+1/2=5/6
and 1/4+1/3=7/12
3/4 times 60 = 45
45 mph is the answer
<u>The factor of 12</u>
<em>1, 2, 3, 4, 6</em>
<u>The factor of 20</u>
1, 2, 4, 5, 10
<u>The common factor of 12 and 20</u>
<em>4</em>
hope this helps you :-)
