To find the perimeter of a rectangle you can multiply the length by 2 and the width by 2, or you can add the four sides together.
The wrong equation is w + 3w = 90 because it only has one width and one length, which would be half the total perimeter.
Answer:
104
Step-by-step explanation:
2x^2+8x−5=0
This is written in the form
ax^2 + bx+c
a =2 b = 8 c=-5
The discriminant is
b^2 -4ac
8^2 - 4(2)(-5)
64 + 40
104
The discriminant is 104
The distance between A and B = |B - A|
We have -12 and -1.
Substitute:
|-1 - (-12)| = |-1 + 12| = |11| = 11
<h3>Answer: 11 units.</h3>
The answer is 67/7 for improper
