Answer:
So the height is 12
Step-by-step explanation:
Let W be the width
Let W- 4 be the height
W2 +(W-4)2 = 400
So: W2 -4W-192 =0
One uses the quadratic solution:
W = (4 + (16 + 4*192).5)/2 = 16
Answer:
3. 33
4. g(x) = 3 (1+n)
Step-by-step explanation:
For the equation, I am not entirely sure that is what your teacher is looking for, but it definitely works! : )
To make it I just said that it looked like there were three different equal parts to the figures, and the area of the parts increases by one every time. So I just added 1 to whatever number it is which gets the area of one of the parts, and multiplied it by 3!
For number 3, I just plugged it into the equation I just made.
g(x) = 3(1+(10))
= 3(11)
= 33
Answer:
9y - 45
Step-by-step explanation:
9(−5+y)
=(9)(−5+y)
=(9)(−5)+(9)(y)
=−45+9y
=9y−45
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
