Let's call the width: w
the lenght is then 3w+4 ("4 more than 3 times the width")
and the parameter would be 2(w+3w+4), that is 2*(4w+4), that is 8w+8.
this is also equal to 18.4:
8w+8=18.4
8w=10.4
w=1.3
this is the width, and the lenght is:
4+3*1,3=4+3.9=7.9
and the area is their product:
1.3*7.9=10.27
+2x-15=0
+2x=0+15
2x=15
X=15/2
X=15/2 or 7,5
Answer:
-1 1/2= 2 lines to the left of -1
1 1/4= 1 line to the right of 1
I hope this helps!
Answer:
y= 4(x+4)(x-1)
Step-by-step explanation:
Since the leading coefficient is 4, put that in front of the parentheses.
The root -4 must be added to x to be graphed correctly. The root 1 must be subtracted from x to be graphed correctly.
y= 4(x+4)(x-1)
