Answer:a,c,d
Step-by-step explanation:
Answer:
By using the rule that the interior angles of any triangle equal 180 we see that:
m<ABC+m<CAB+m<ACB=180°
Therefore,
(2x+15)+(x+10)+(3x+5) = 180°
Now we have an equation and can solve for x:
Combine like terms:
(2x+15)+(x+10)+(3x+5) = 180°
6x+30=180°
6x+30-30=180-30
6x=150
x=25
To check our work just plug in 25 for x in each equation and the sum of those answers should add up to 180:
2x+15
2(25)+15
65
x+10
25+10
35
3x+5
3(25)+5
75+5
80
65+35+80=180
x=25 is valid
Step-by-step explanation:
Given equation is 
.
Now we need to find about what are the key aspects of the graph of , where b is a real number.
We know that square of any number is always positive.
then 
must be a positive number.
So that means for any real number b, as the value of b increases then graph of f(x) shifts downward by units as compared to the graph of parent function 
Write the conjugates of them then FOIL both the top and bottom, then factor
