Answer:
B. One
Step-by-step explanation:
Since the two angles are already given, the value of the third angle is already fixed. The third angle can be found by the sum of both angles subtracted from 180. Since 2 angles and lengths are already given, there can only be 1 triangle.
Hope this helps!
If not, I am sorry.
I believe it’s the second table, (5, 25), (7, 49), (9, 81).
(2x+1)=Jeremy´s age
(2x+3)=Sam´s age.
we suggest this equation:
(2x+1)(2x+3)=783
4x²+6x+2x+3=783
4x²+8x-780=0
x²+2x-195=0
We solve this quadratic equation:
x=[-2⁺₋√(4-4*1*(-195))]/2=(-2⁺₋28)/2
x₁=(-2-28)/2=-15 this solution is not valid.
x₂=(-2+28)/2=13
Jeremy´s age=2x+1=2*13+1=27
Sam´s age=2x+3=2*13+3=29
Answer: x=25
Step-by-step explanation:
7+x=32 (subtract 7)
x=25
Because it is normally set to only find real roots, not complex roots
if you are smart, you can use the factor function and use your head to find those roots
