The easiest thing to do to solve all of these is to use the quadratic equation.
The first number (the one attached to x^2) is equal to a. The second number (the one attached to x) is b. The final number (the one with nothing attached) is c.
We can start with:
x + y = N
where
x is the first 3 digit number
y is the second 3 digit number
In order to get the maximum value of N, the digits used must 9,8,7,6,5,4
To maximize, 9 and 8 must be added. This can only happen if 9 is the first digit of the first number and 8 is the first digit of the second number. The same idea is applied to the other digits. So
x must be 975 and
y must be 864
N = 975 + 864 = 1839
The answer is option 2 and option 6
Answer:
96 , 144
Step-by-step explanation:
Ratio = 2 : 3
2x + 3x = 240
5x = 240
x = 240/5
x = 48
2x = 2*48 = 96
3x = 3*48 = 144
Answer:NO
Step-by-step explanation:it needs at least 1 90 degree angle
