That is a quadratic trinomial.
Its largest degree is 2 (which makes it quadratic), and it has 3 terms separated by addition operators (which makes it trinomial).
You can go through the set and test each one out:
x=0:
2(0)+3 ≥ 7? Or 3≥7? No
x=0.6:
2(0.6)+3≥7? 4.2≥7? No.
x=2:
2(2)+3≥7? 7≥7? Yes.
x=4:
2(4)+3≥7? 11≥7? Yes.
x=6:
2(6)+3≥7? 15≥7? Yes.
The set is {2, 4, 6}.
Change each number to an improper fraction.
Put in lowest terms if possible.
Multiply the numerators and then the denominators.
Put answer in lowest terms.
Answer:
n = -13
Step-by-step explanation:
38 = -2n + 12
<em>Subtracting</em><em> </em><em>1</em><em>2</em><em> </em><em>from</em><em> </em><em>both</em><em> </em><em>sides</em><em>:</em>
==> 38 - 12 = -2n + 12 - 12
==> 26 = -2n
<em>multiplying both sides by (-1)</em><em>:</em>
==> -26 = 2n
<em>dividing</em><em> </em><em>both</em><em> </em><em>sides by 2:</em>
==> -13 = n
Answer:
15 ft
Step-by-step explanation:
12^2 + 9^2 = c^2
144 + 81 = c^2
225 = c^2
c = 15
