Answer:
Step-by-step explanation:
perimeter = sum of the sides = (3y+5) + (y-4) + (6y) = 10y + 1
If (x+5) is a factor the equation will equal zero when x=-5 so
3(-5^2)+14(-5)+k=0
75-70+k=0
5+k=0
k=-5
Answer: 170
Step-by-step explanation: To find the percent change, simply multiply this number by 100.
Answer:
3x + x + 3x + x = 360
8x = 360
x = 45
3(45)= 135
