<span>Which trinomial is a perfect square trinomial?
A) a^2 - 12a + 36
B) a^2 - 8a + 64
C) a^2 - 6a + 36
D) a^2 - 4a + 64</span>
Start by writing your own expression.
x is the smaller number and x + 1 is the next number
x(x + 1) = 420
x^2 + x - 420 =0 ⇒ constant = -420
Answer:
I dont know if its right but I think its 50
Step-by-step explanation:
The answer is D. Maria selected a multiple that is not the least of the common multiples.
We see from the list that the least common multiple between 6 and 15 is 30, not 60.
<span> A </span>ratio<span> compares values. A </span>ratio<span> says how much of one thing there is compared to another thing. We do as follows:
length of photo/ length of a carpenter bee = ratio of the two
13.5 / 6x10^-3 = 2250
Therefore, the photo is 2250 longer than the carpenter bee.</span>
