Step-by-step explanation:
2x-1=0
2x=1
x=1/2
x+5=0
x=-5
Final answer: B
SA=4pir²
given SA=12.56
12.56=4pir²
divide both sides by 4
3.14=pir²
3.14=3.14r²
divide both sides by 3.14
1=r²
sqrt both sides
1=r
the radius is 1 in
Answer:
The factors of x^3+2x^2+5x+10 are (x^2+5)(x+2)
Step-by-step explanation:
x^3+2x^2+5x+10
Group the expression by two:
=(x^3+2x^2)+(5x+10)
Factor out GCF in each group.
=x^2(x+2)+5(x+2)
Note:(The binomials in parentheses should be the same, if not the same... there is an error in the factoring or the expression can not be factored.)
Now factoring out the GCF which basically has you rewrite what is in parentheses and place other terms left together:
=(x^2+5)(x+2)
Thus the factors of x^3+2x^2+5x+10 are (x^2+5)(x+2)....
