Answer:
Area = 8 sq units
Step-by-step explanation:
Given vertices:
(1, 1),(1, 3),(5, 3),(5, 1)
To figure out area graph the vertices and count how many units are inside.
8 sq units
So 8 sq units is the area.
Area = 8 sq units
Answer:
If D< 0, the roots of the quadratic equation will b complex.
Step-by-step explanation:
Let 
is the given quadratic equation.
So, if the Discriminant (D) = 
, the the equation will have only complex solutions.
Complex roots are represented in the form of 
1. <u> x represents the X axis (real) co ordinate,</u>
<u>y represents the Y axis (imaginary) coordinate</u>
<u />
<u />
2. Also, the graph of the with equation D < 0 NEVER CROSSES the X - axis, as there are no real roots of the equation, only complex roots.
3. Here. roots are always identical but are opposite in signs. Such pair or roots with opposite sign are called CONJUGATE PAIRS.
Answer:
1/4
Step-by-step explanation:
Rebecka already chose a retriever, so the puppies left for Aaron to pick are:
2 poodles
2 terriers
1 retriever
Total: 4
Number of retrievers left after Rebecka's pick: 1
p(Aaron picks retriever) = 1/4
In order to answer this one, it's really really really really helpful if you know what the law of cosines says. In fact it's absolutely necessary.
The law of cosines says if you know two sides of a triangle and the angle between them then you can use that information to find the length of the third side.
In the picture you know the lengths of two sides and you know the angle between them. So you can use the law of cosines to find the length of the third sidethat. That's side AC.
432
I know this bc if you do the equation is gonna be 3•8•2•9 then it will be 24•2•9 then it’s gonna be 48•9 to get 432 as your answer
