Answer:
x value would be 2
Step-by-step explanation:
The computation is shown below:
Given that
x^2 + 2x = 8
x^2 + 2x - 8 = 0
x^2 + 4x - 2x - 8 = 0
x(x + 4) - 2(x + 4) = 0
(x - 2) (x + 4) = 0
So, x value would be 2
x - 2 = 0
x = 2
Here is the answer to your question

x= -1.4 i think
Step-by-step explanation:
Answer:
No
Step-by-step explanation:
The only arithmetic sequence of side lengths that will form a right triangle is (3, 4, 5) or some multiple of that, such as (9, 12, 15).
Sides of length 10, 11, 12 cannot form a right triangle.
Answer:
<em>1 : 2</em>
Step-by-step explanation:
<u>First situation</u>
sides of triangle:-
a=x, b=2x, c=3x
then perimeter = a+b+c
perimeter = x + 2x + 3x
<em>Perimeter = 6x</em>
<u>Second situation(sides are doubled)</u>
sides of triangle:-
a=2x, b=4x, c=6x
then perimeter = a+b+c
perimeter = 2x + 4x + 6x
<em>Perimeter = 12x</em>
<u>Ratio of first situation to second </u>
Perimeter of first situation : Perimeter of second situation
6x : 12x
<em>1 : 2</em>
