Answer:
A) 2x³+11x²+8x-16
Step-by-step explanation:
When you multiply s(x) by t(x) you get something like this:

Answer:
The statement is false
Step-by-step explanation:
we know that
if the triangle is a right triangle
then
the triangle must satisfy the Pythagoras Theorem

we have



substitute



therefore
Is not a right triangle
The statement is false
Use the formula that states that the sum of the angles of an n-sided polygon is given by
S=(n−2)180
0
........(1)
Since we are given that the two angles are right angles and each of the remaining angles is 144
0
, therefore, the sum is:
S=90
0
+90
0
+(n−2)144
0
.........(2)
Therefore setting (2) equal to (1) we get
(n−2)180
0
=90
0
+90
0
+(n−2)144
0
⇒(n−2)180
0
−(n−2)144
0
=180
0
⇒(n−2)(180
0
−144
0
)=180
0
⇒(n−2)(36
0
)=180
0
⇒n−2=
36
180
⇒n−2=5
⇒n=5+2=7
Hence, the polygon has 7 sides.
Answer:
The product of 6 and a number
Step-by-step explanation:
There isn't any "real" mathematics needed to find the answer, just common background knowledge:
6x = 6 times x,
and product is referencing multiplication
(Since quotient is for division, difference for subtraction, and sum for addition)
considering we need to represent an expression which uses multiplication in words, the correct answer is:
O the product of 6 and a number
The formula for length of an arc on a circle is given by the formula:
,
where 'r' is the radius of the circle and 'x' is the measure of the central angle of the arc.
We have to determine the value of radius 'r'.
Since, 
By Cross multiplication, we get




Therefore, the radius 'r' is given by
.
Option 4 is the correct answer.
