Answer:
Height and base are both 12 in
Step-by-step explanation:
Formula area triangle: area = (height * base) /2
Since for the first triangle height and base are the same we will call is x.
The area for the first triangle is
area = (x^2) /2 = 0.5x^2
The new triangle area is
first triangle - 36 = ((x/2) * x)/2
0,5x^2 - 36 = (0,5x * x)/2
0,5x^2 - 36 = (0,5x^2)/2
0,5x^2 - 36 = 0,25x^2
0,25x^2 = 36
x^2 = 144
X = square root (144) = 12 in
Answer:
-10/-5 (the third option)
Step-by-step explanation:
all of the others are negative, but since there are two negative signs on this fraction, it becomes positive
hope this helped/made sense and have a great day!
The dimensions would be 2 by 2.
We are fencing in 3 sides. The southern side is twice as expensive as the other two sides; the eastern and western sides together equal as much as the southern side. We have $80 to spend.
20x+10x+10x = 80
40x = 80
x = 2
This means that we can have 2 feet on all sides, for a total of 10(2)+10(2)+20(2)= 80.
