We have similar triangles allowing us to form the proportion
x/(x+9) = 4/10
which is basically the ratios of the corresponding sides
Solve for x
x/(x+9) = 4/10
x*10 = 4*(x+9)
10x = 4x+36
10x-4x = 4x+36-4x
6x = 36
6x/6 = 36/6
x = 6
Answer: 6
|-40| = 40
|5| = 5
40 - 5 = 35
i would say the answer is 35 because i have no idea what •\• means ;-;
You would do 8%/100% = x/ 2.5million and then cross muiply
Answer:
If it is ax^2 + bx + c = 0 then it is a quadratic equation
Step-by-step explanation:
Answer:
19km
Step-by-step explanation:
The formula for the perimeter of a triangle is: S+S+S.
So;
19km+19km+a=57km
a=57km-19km-19km
=19km
