513,900
You round the 869 up to 900 because 69 is over 50
Answer:
solve with algebraic method: 3x^2+10x=8. Solution- x = 2/3 x = -4
First, we have to make one of the x's have the same coefficient so they can cancel each other out (or eliminate)
3(x+y) = 3(2)
you're going to have to do it to both sides to keep it balanced
3x+3y=6
now line them up and add them
3x+3y= 6
+ (-3x+4y=15)
since the 3x and -3x add up to 0x and cancels each other, you're left with
7y = 21
divide both sides by 7
y=3
plug in the y into one of the original equations
x+y=2
x + 3 = 2
subtract 3 from both sides
x = -1
x = -1 , y = 3
In your question where as their is a figure and ask what type of triangle is shown in the figure and i think the answer is Equilateral Triangle. I hope you are satistfied with my answer and if you need some clarification, please feel free to ask for more
Answer:
SAS
Step-by-step explanation:
The triangles are similar by SAS. Two side lengths are given, and we know that vertical angles are congruent.
It is not SSS because we do not know the side lengths of FG and BC.
It is not AA because we do not know two angle measurements.
