Determine the 7th term
The nth term of a gp is:

So, we have:





Answer:
a). true
b). true
Step-by-step explanation:
a).
Given : If a = 5, then ac = 5c
Let c be any constant.
a = 5 (given)
Therefore, ac = 5c
Here a is given a constant value (5), also let assume c to be a constant. So when we multiply each term we will get a constant value of 5c. The ratio does not change.
Hence proved.
b).
Given : If ac = 5c, then a = 5
Let c be any constant
It is given, a = 5
Therefore, ac = 5c
Here the product of two terms is given as 5c, where c is assume to be a constant. Then as a product rule, the value of a will be 5. The ratio will not change.
Hence proved.
Answer:
Option A. Triangle STR
Step-by-step explanation:
we know that
If two triangles are congruent, then the corresponding sides and the corresponding angles are congruent
In this problem
If the two triangles of the figure are congruent
then
the corresponding sides are
MN and RS
NO and ST
MO and RT
and the corresponding angles are
∠N≅∠S
∠O≅∠T
∠M≅∠R
therefore
NOM≅STR
Answer:
3x^2+2x+8
Step-by-step explanation:
1. x^2+2x^2=3x^2
2. -3x+5x=2x
