Answer:
2x+ 2.1 = 7.5
x=2.7
Step-by-step explanation:
The perimeter of an isosceles triangle with sides x and y is
2x+y = P
I put y as the single side since the question said y is the shortest side. It should say shorter sides if the two sides with the same length are smaller than the third.
We know y =2.1 and P = 7.5
Substituting these values in, we get
2x+ 2.1 = 7.5
Subtract 2.1 from each side
2x+2.1 -2.1 = 7.5 -2.1
2x= 5.4
Divide each side by 2
2x/2 = 5.4/2
x = 2.7 m
The factor of mn+5m-3n-15 is 6m-4n-15.
The equation solution is y=1, so the two ordered pairs may contain any value of x and a value of 1 for y. (Ex: (-8,1) and (8,1))
Answer: y = one twelfth(x + 2)2
