Answer:
x=-2 x=-1
Step-by-step explanation:
f(x)=x² +3x+2
Set the function equal to zero
0=x² +3x+2
Factor
What 2 numbers multiply to 2 and add to 3
2*1 = 2
2+1 = 3
0 = ( x+2) (x+1)
Using the zero product property
x+2 =0 x+1 =0
x=-2 x=-1
Answer:
x= 30°
Step-by-step explanation:
The shape is irregular, and it has 5 angles, and the formula for finding a n-sided polygon
is (n-2)180°. To get the total angle, (5-2)180°=3×180°=540°. X°+4x°+4x°+135°+135°=540° ; 9x°+270°=540° ; 9x°=540°-270° ; 9X°=270° therefore, X=270°÷9= 30°•
Answer:
(x - 5) and (x + 4)
Step-by-step explanation:
Since -20 = (-4)(5) or (4)(-5), and since -5x + 4x becomes -1x, we know right away that the factors are (x - 5) and (x + 4).

Answer:
6:10 -> simplfied is 3:5
Step-by-step explanation:
This question is really is if you think about it for a while. If you have a ratio that is like 6:10 or 6/10 all you have to do is multiply it by two (since it can only go in two times in this ratio). When you simplfy your answer, you will get 3:5.
Hope this helped you guys!
