Hope this helps!!

Step-by-step explanation:

2ya and 2yb where a and b have no common factors and a and b are polynomaals

b=(x+4)(x+5)

no common factors betwen a and b

2ya=2y(x+2)(x+3)=2yx²+10xy+12y

2yb=2y(x+4)(x+5)=2yx²+18xy+40y

the 2 polynomials  are  2yx²+18xy+40y and 2yx²+10xy+12y

Find three consecutive odd integers with a sum of 75
marusya05 [52]

Answer:

23, 25, 27

Step-by-step explanation:

first integer will be X, second will be (X+2), and the third will be (X+4). They will all be summed up and set equal to 75.

(x) + (x + 2) + (x + 4) = 75

combine like terms:

3x + 6 = 75

subtract 6:

3x = 69

divide by 3 to find value of X:

\frac{3x}{3}  =  \frac{69}{3}

x = 23

plug in X in o red der to finger the rest of the integers.

(X+2)= (23+2)=25

(X+4)= (23+4)=27
