Add up all the lengths of the garden and you will be able to get the perimeter.
Answer:
6
Step-by-step explanation:
The circumference of a circle is 
, so
. We can use this because the area of a circle is
. Thus,
.
X+x²=30
x²+x-30=0
(x+6)(x-5)=0
x=-6 or x=5
Explain: it’s equals to 20
Answer:
A. Discriminant = 116
B. Number of solutions for the quadratic equation = 2
C. Type of solutions (circle one):Imaginary
D. Type of solutions (circle one):irrational
Step-by-step explanation:
The given quadratic equation is

We rewrite in standard form to get;

The discriminant is

where a=1, b=8, c=-13
We substitute to get:



Since the discriminant is great than zero, we have two distinct real roots
