Answer:
1:8
Step-by-step explanation:
Given that in square ABCD, point M is the midpoint of side AB and point N is the midpoint of side BC.
Let the side of the square be a.
Area of square ABCD = 
The triangle AMN is having two legs of a right triangle as half of side of the square
i.e. Triangle AMN has base = height = a/2
So area of triangle AMN = 
Ratio of the area of triangle AMN to area of square ABCD
= 1:8
This is fairly simple. Just do 2x15 to get your answer 2x15=30. Explanation if it is 2 times longer you would do 2 and then when it says it is 15 diagonal that is where the 15 comes in and it would be 2x15. So your answer is 30
Answer:
The second number is four more than, two times the first number. The third ... Start by writing an expression for each of the three numbers. They are all formed from the first number, so let's call the first number x . Let the first number be x. The second number is 2x+4. The third number is 3x−5. We are told .
Step-by-step explanation:
To find slope, pick any 2 points and use formula: (y2-y1)/(x2-x1)
2 points on line: (4,0), (0,-2)
(-2-0)/(0-4) = -2/-4 = 1/2
a) the slope is 1/2
Y = 1/2x + b
0 = 1/2(4) + b
0 = 2 + b, b = -2
b) -2 is the y intercept
Put the equation together
c) y = 1/2x - 2
