Step-by-step explanation:
yes yes !!
Factor by grouping. Group up the terms into pairs, factor each pair, then factor out the overall GCF.
x^3 + 2x^2 - 16x - 32
(x^3 + 2x^2) + (-16x-32) ... pair up terms
x^2(x + 2) + (-16x - 32) ... factor x^2 from the first group
x^2(x + 2) - 16(x + 2) ... factor -16 from the second group
(x^2 - 16)(x + 2) .... factor out (x+2)
(x - 4)(x + 4)(x + 2) .... Use the difference of squares to factor x^2-16
---------------------------
The original expression completely factors to (x - 4)(x + 4)(x + 2)
The three factors are x - 4 and x + 4 and x + 2
Answer:
20.3cm^2
Step-by-step explanation:
Bullseye has a circular shape. So area of a bulleyse = Pi x (radius) ^2
Díameter is 2 inches = 5. 08cm
But radius = diameter /2
Radius = 5.08cm /2
Radius = 2.54cm
Hence Area of bulleyse = 3.14 x (2.54) ^2
= 3.14 x 6. 451 cm^2
= 20.256 cm^2
=20.3cm^2 (to nearest tenth)
Answer:
Acute
Step-by-step explanation:
Note the definitions:
Obtuse: At least one of the angles are greater than 90°
Equilateral: All angles are congruent & equal to 60°
Acute: All angles are less than 90°
Right: At least one angle is equal to 90°
In this case, the triangle is a D) acute, for it fits the requirement for being an acute... all angles are less than 90°.

Answer:
Option b) is correct.
The completed factor of given expression is 
Step-by-step explanation:
Given expression is 
To find the completed factor for the given expression:
:
Taking the common number "2" outside to the above expression we get
Now rewritting the above expression as below
(since 16 can be written as the number 2 to the power of 4)
The above expression is of the form 
Here 
and 
Therefore it becomes
The above expression is of the form
Here 
and 
Therefore it becomes
Therefore
Option b) is correct.
The completed factor of given expression is
