Answer:
second option
Step-by-step explanation:
The perimeter is the sum of the 3 sides of the triangle
Given
hypotenuse = x
and
the combined length of the legs = 2x , then
perimeter = x
+ 2x
20 nickels
20 nickels = $1.00
15 dimes= $1.50
which is $2.50
Answer:
x = 
Step-by-step explanation:
Given
x - 5 = 
Multiply through by 8 ( the LCM of 4 and 8 ) to clear the fractions
6x - 40 = 3 ( add 40 to both sides )
6x = 43 ( divide both sides by 6 )
x = 
Answer:
±11.18
Step-by-step explanation:
the function is:

and to find the roots we need to find which values of
makes the function result in zero:

solving for
:

A square root has two solutions, one positive and one negative, so the solutions are:
±
≈ ±11.18
the roots of the quadratic equation are +11.18 and -11.18
Answer: 6
Since one of the points is at the origin, then you can take the number point on the x axis and multiply it by the point on the y axis, and you get 12. To find the area of a triangle, you must use base x height divided by 2. Divide 12 by 2 to get 6.
