Hello :
(x+m)(x+n) =x² +mx +nx +mn
a trinomial is factored as (x+m)(x+n) is : x² +(m+n)x +mn

A. The degree of the trinomial : 2

B. The constant term of the trinomial : mb

C. The coefficient of the x-term of the trinomial : m+n

D. The coefficient of the x^2-term of the trinomial : 1

katen-ka-za [31]

If events E1 and E2 are mutually exclusive, it means that it is impossible for them to happen together. The probability of the occurrence of one or more of these events is the sum of their individual probabilities. The answer for this item would be,
P(E) = P(E1) + P(E2) + ...

What’s the cosine of

Vsevolod [243]

Answer:

√23/√45 or √23/3√5

Step-by-step explanation:

Cosine is adjacent over hypotenuse. Angle W has an adjacent side of WU(√23) and WV .You know the adjacent but not the hypotenuse, so you will use the formula a^2+b^2=c^2 to find the hypotenuse. Plug in the sides for A and B -> (√23)^2+(√22)^2=c^2. Simplify it --> 23+22=c^2 --> 45=c^2. Solve for C alone (not c^2). √45=c. Then use the cosine formula (adjacent/hypotenuse) to plug in the numbers.
