Although you didn't provide any answer choices:
A trinomial is an expression with exactly three terms that can't be combined an example would be this
x^2 - 3x + 1
None of those terms can be combined
x^2 + 3 - 4 has three terms but it isn't considered a trinomial because you can simplify it to x^2 - 1 which is known as a binomial because it has 2 terms in it's simplified form.
hope this helps C:
Y=4x+19. To check your answer you can plug in the point (-4,3) into the equation to check your answer. Y=4x+19, 3=4(-4)+19, 3=3
I think it's C because it says an even number and the equivalent fraction for that numb number 40 tenth .
Answer:
13.7 mm
220cm
863.6
0.02 km
29000m
Step-by-step explanation:
Cm = 10mm, so 1.37 cm = 13.7 mm.
m = 100cm, so 2.20 m = 220cm.
in = 25.4 mm, so 34in = 863.6
m = 0.001 km, so 20m = 0.02 km.
km = 1000 m, so 29km = 29000m.
