Answer:
Value of x=4 and y=-13/3
Step-by-step explanation:
We need to solve the systems of equations
Solving using substitution method:
Let:
Find value of x from eq(1) and put in eq(2)
Put value of x in eq(2)
Now, finding value of x by putting value of y in eq(1)
So, Value of x=4 and y=-13/3
Let x represent the middle one. Then the largest is x+2; the smallest is x-2.
(x+2) +2(x-2) = 25
3x = 27 . . . . . . . . . . simplify, add 2
x = 9 . . . . . . . . . . . . divide by 3
The integers are 7, 9, 11.
2=28 divide both get 14 . So each cd is 14$. So now 28+28=56 (4 cd's) plus 14 (1 more cd) =5 so 5 is 70.
For this case we have that the area of the triangle is given by:
Where:
b: It's the base
h: It's the height
We have to:
The atura will be given by:
So, the area is:
Answer:
144
