Answer:
Step-by-step explanation:
Since triangle ADE and triangle ABC are similar, that means their sides are proportional, thus we get the equation
Thus the value of x is 4
Answer:
126 all you have to do is take the two measurements and add them together
Answer:
The last one
Step-by-step explanation:
You start off with 50.
It says the water is being drained so the slope is negative.
Answer:
the answer is 6992
Step-by-step explanation:
All you have to do is subtract 18697 from 25689:
25689-18697= 6992

Assign the following variables for the origina3l rectangle:
let w = width let w + 8 = length and the area would be w(w + 8) = w² + 8w
No for the second rectangle:
let (w + 4) = width and (w + 8 - 5) or (w + 3) = length
Area = length x width or (w + 4)(w + 3) = w² + 3w + 4w + 12 using the foil method to multiply to binomials. Simplified Area = w² + 7w + 12
Now our problem says that the two area will be equal to each other, which sets up the following equation:
w² + 8w = w² + 7w + 12 subtract w² from both sides
8w = 7w + 12 subtract 7w from both sides
w = 12 this is the width of our original rectangle
recall w + 8 = length, so length of the original rectangle would be 20
