Answer:

Step-by-step explanation:
1) In this question we've been given "a", the leading coefficient. and two roots:

2) There's a theorem, called the Irrational Theorem Root that states:
If one root is in this form
then its conjugate
. is also a root of this polynomial.
Therefore

3) So, applying this Theorem we can rewrite the equation, by factoring. Remembering that x is the root. Since the question wants it in this expanded form then:

Answer:
B
Step-by-step explanation:
two sides are longer than the other two, D could also be one of the choices but rectangles have two parallel lines and have shorter sides at the sides
Answer:
Approximate probability that
is less than 2 = 0.1515
Step-by-step explanation:
Given -
Mean
= 2.2
Standard deviation
= 1.4
Sample size ( n ) = 52
Let
be the mean of accidents per week at the intersection during one year (52 weeks) .
probability that
is less than 2 =
=
Putting 
=
( Using Z table )
= 0.1515
Answer:
Area of the rectangle A = 32 x - 8
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given that the length of the rectangle(l) = 8x-2
Given that the width of the rectangle (w) = 4
Area of the rectangle = length × width
A = (8x - 2) × 4
A = 32 x - 8
<u><em>Final answer</em></u>:-
Area of the rectangle A = 32 x - 8
