Answer:
The answer is 14
Step-by-step explanation:
Yes it is LCM and GCF because you are trying to a factor that they both have
1. 0.5625
2. 144
3. -2
4. -16
Answer:
Try 31 degrees/ Hard to explain but try it
Step-by-step explanation: cause between angle a, c, b - and angle a, o , c - their is an intersect. on that intersect onside is 62 degrees and the other side is 118 degrees; now thats a 180 degrees angle cause the base of the intersect is straight. Now this intersect is connected to the obtuse angle of the bottom triangle which is 118 degrees. Knowing that you can figure out the other corners of the traingle. The last two acute angles of to be congruent.
Answer:
x=-11, -1, and 3
Step-by-step explanation:
x^3+9x^2-25x-33=0
There are formulas to solve cubics, but that probably is not the way you are expected to go. Here is a trial and error approach that works in this case.
Assume that the cubic can be factored and that the roots are r1, r2, and r3. Then the factored form is
(x-r1)(x-r2)(x-r3)=0
This shows that the constant must equal the product of the roots.
(r1)(r2)(r3)=-33
One possibility is that the roots are integers. In this case, a factor of 33 might work. Prime factorization of 33 gives 3 and 11. Try 3. Then (x-3) is a factor.
Divide the cubic by (x-3). It works. the result is
x^2+12x+11
This has factors of (x+11) and (x+1). Therefore, the roots are 3, -1, and -11
