Answer:

Step-by-step explanation:
3 x 4 - 5 = 7
The perimeter of triangle is: 5.5x+9
Step-by-step explanation:
Lets define perimeter firsst.
A perimeter is the boundary line measurement of any closed geometric figure"
Given
Side 1: 
Side 2: 
Side 3: 
The perimeter of a triangle is given by:

Putting the values

Hence,
The perimeter of triangle is: 5.5x+9

Recall that in a geometric sequence, you multiply the "current" one by the common ratio to get the "next" so, if you divide "next"/"current", the quotient is just the common ratio,

notice, all we did was, divide the value, by the number to its left-hand-side.
The answer is 4.1

Answer:
A. p(x) + q (x) =2x^4 + 3x^2 - 5x + 7-2x^2 + 4x - 3 =2x⁴+x²-x+4
B. 2 • p (x)=2(2x^4 + 3x^2 - 5x + 7)=4x⁴+6x²-10x+14
C. p (x) - q (x) =2x^4 + 3x^2 - 5x + 7-(-2x^2 + 4x - 3 )=2x^4 + 3x^2 - 5x + 7+2x²-4x+3=2x⁴+5x²-9x-2
D. 3 • p (x) + 4 • q (x) =3(2x^4 + 3x^2 - 5x +7)+4(-2x^2 + 4x - 3 )=6x⁴+9x²-15x+21-8x²+16x-12=6x⁴+x²+x+9
E. p (x) • q (x)=sorry it is quite long.
F. (P (x) ) ^2this too.
