Hey there!
The equation for axis of symmetry is 
The A, B, and C are:
Ax+By+C= f(x)
A=4 B=-8 C=12
So we have:
Two negatives make a positive.
8/8= 1
x=1 is the correct answer.
I hope this helps!
kaikers
2/3 there you go I Calculated it
There isn't any "biggest".
If you ever meet anybody who tells you that he has the biggest number
in the world, ask him to let you see it, and when he does, take it and add
' 1 ' to it. Then YOU'll have a number that's bigger than HIS number, and
that proves that his was not the biggest.
1. X=5
2. X=-5
3. Y=10
Step-by-step explanation:
those are the answers
The length of each of its parallel side are 30 cm and 40 cm.
<u>Step-by-step explanation</u>:
- Perimeter of parallelogram = 140 cm.
- The one side of parallelogram = x cm.
- The other side of parallelogram = x+10 cm.
Perimeter of a parallelogram = 2 (base+height)
⇒ 140 = 2(x+x+10)
⇒ 140 = 2(2x+10)
⇒ 140 = 4x+20
⇒ 4x = 120
⇒ x = 120/4
x = 30 cm
∴ The longer side = 30+10 = 40 cm
