In this equation y would equal 4 or it could be 1
115=d-259 that's how to write it
4x²=16
x²=16/4
x²=4
√(x²)=+/-√4
x(1) =2, x(2)=-2
Based on property of triangles, if two of the three sides are exactly doubled, so will the resulting length. Both answers are 18.
Answer:
A = 90
Step-by-step explanation:
We need to find the length of the base
Let EF be the base
length = change in x (since the y's are the same value)
= (9--9) = (9+9) = 18
Now we need to find the height (change in y values)
-7 --2
-7 +2 = -5
But the value is positive because we are finding the distance
height is 5 units
A = bh
A = 18*5
A = 90
