So we're trying to solve for x. To do this we need to balance the equation.
-121 -4x = 39 + 6x
Get x on one side; add 4x to both sides.
-121 = 39 + 10x
Subtract 39 from both sides (remember when subtracting a negative to a negative, it's basically just adding with negative signs).
-160 = 10x
Divide both sides by 10.
x = -16.
Hope this helps!
This is true that this is not a function because no x-value can be repeated.
Answer:
x=1 and y=-2
Step-by-step explanation:
5-2i-7=-2-2i
x-(3-yi)=x-3+yi
we write this equation -2 - 2i = (x-3) +yi
so -2=x-3 and -2i=yi
+3 +3 :i :i
1=x -2= y
so x=1 and y= -2
i think 0 thats what it said online
Answer:306
Step-by-step explanation:
since the width of the bottom square is 10, you split it between the triangles on top. You have to do this because 7 is not the whole width of the two triangles. So then the width of the triangles would be 12, 12 times 9 is 108, you'd have 216 total for both triangles and then the area of the square is 90, 90 plus 216 is 306.
