I got the answer by doing nothing then I did nothing and finally I did nothing hope you find this helpful as I just wasted your time
Answer:
<u><em>ΔEAB ≅ΔFCD</em></u>
Step-by-step explanation:
As ABCD is a parallelogram opposite sides are equal s AE ≅CF ,also AB≅ DC . Both E and F bisect the opposite lines in equal halves.
The parallelogram has a property that its opposite angles are equal . Therefore ∠c≅∠a, ∠d≅∠b
Using the SAA≅SAA postulate we conclude that ΔEAB ≅ΔFCD
Answer:
Step-by-step explanation:
Assuming the following data
X: 44, 44, 11, 11, 55
Y: 66, 55, -1, -3, 88
We want to find a linear model
For this case we need to calculate the slope with the following formula:
Where:
So we can find the sums like this:
With these we can find the sums:
And the slope would be:
Nowe we can find the means for x and y like this:
And we can find the intercept using this:
So the line would be given by:
Answer:
length=8 , wide=5
Step-by-step explanation:
Let length=x and wide=y
convert the question into two equations
3+y=x .......1
xy=40 .......2
so we need to substitute x into y or y into x
x=3+y ,
(3+y)y=40
y²+3y=40
y²+3y-40=0
from that use calculator or manually factorise it
(y+8)(y-5)=0
y= –8 , y=5
we need to choose positive answer so y=5
then find for x
5x=40
x=8
