Help me Please..
Fittoniya [83]
Just general definitons:

a TRInomial has 3 terms (tri means three)
a BInomial has 2 terms (bi means two)
a MONOmial has 1 term (mono means one)

the degree is the highest exponent found in the algebraic expression

so they should be pretty easy to solve with that information, but just in case:

1. trinomial, degree of 4
2. binomial, degree of 3
3. monomial, degree of 2

for the final question, all you have to do is plug in 2 for x, so

(2)^2 - 2(2) + 1

4 - 4 + 1

so the answer is 1

Help me pls it’s urgent
earnstyle [38]

Answer:

<A = 115

<C = 50

Step-by-step explanation:

<A + <B + <C = 180

SO

(4X -13) +15 +(X+18) =180

5X +20 =180

5X = 160

X= 32

LOG IN TO <A = 4*32 -13 = 115

<C = 32+18 = 50

PLZZZ HELP ME I DON'T GET THISq
just olya [345]

Answer:

Step-by-step explanation:

To distribute means to multiply everything outside the parenthesis with everything inside the parenthesis, so in this case 7x8 then 7(x) then 7x2 so that is equal to 56 + 7x + 14, so combine the 56+14 so we get 7x + 70.  I hope '7' is part of the problem and not the question number
