Answer:
2x+20+3x+10 = 180 (int. angles, parallel)
5x+30 = 180
5x=150
x=30
(x^2-5)(3x-1)
Here's how I got this answer:
I found the GCF for each part of the polynomial.
3x^3 and -15x both contain 3x, and -x^2 and 5 share -1.
I then can divide the polynomial by 3x-1, and I get x^2-5
(Okay, that's not what I really did, but I can solve these on sight and don't remember the proper way to do it.)
Answer:
Step-by-step explanation:
Let two consecutive odd numbers
x, x+2
According to condition
X(x+2) = 899
x2 +2x -899=0
X2 +31x -29x -899=0
x(x+31) -29(x+31)=0
(x+31)(x-29)=0
X=-31 or x =29
Now,
X=29
X+2= 29+2 = 31
Two consecutive odd numbers is 29 and 31
