2p^2 + 30p + 108 2(p + 6)(p + 9)
----------------------- = -------------------- = 2(p + 9) / (p - 1)
p^2 + 5p - 6 (p + 6)(p - 1)
Its the first choice
Answer:
$138
Step-by-step explanation:
We can first turn the words into a mathematical equation by substituting words with the information we have:
Total earning - ( Price of three books)
$180 - (Price of one book x 3)
$180 - ($14 x 3)
Finally, after we have created the mathematical equation, we solve it!
$180 - ($14 x 3)
$180 - $42
$138
If I remember correctly I think its B. 15 mm
Answer:
5m-50
Step-by-step explanation:
Let Diego current age be x,
Given that Diego’s current age is five times Martina’s age ten years ago
Martina current age = m years
10 years ago Martina's age = m-10
Hence we have
x = 5(m-10) = 5m-50
So we find that Diego's current age can be expressed in terms of m as
Deigo's current age= 5m-50
Verify:
Deigo current age = 5m-50
Hence Martina age 10 years ago = 5m-50 divided by 5 = m-10
Martina current age = m-10+10 = m
Verified.
