The ' c ' in 'gcf' and in 'lcm' stands for 'common'. 'Common' means 'same for all of them'. There's nothing common until you have at least two things. There's no such thing as the gcf or the lcm of only one number.
Is 105 - 42 = 63.
The answer is B. 63
Answer:
<u>The answer is m = 5</u>
Step-by-step explanation:
Let's solve the proportional equation, this way:
3/m-2 = 7/m+2
3 * (m + 2) = 7 * (m - 2) [Lowest common denominator (m + 2) * (m - 2)]
3m + 6 = 7m - 14
-4m = -14 - 6 (Like terms)
-4m = -20
m = -20/-4
m = 5
<u>The answer is m = 5</u>
Answer:
AE = 3
Step-by-step explanation:
The three interior angles of any triangle add to 180 degress. Therefore,
180-(120 + 40) = the third angle.
So, 20 is the third angle
