Find the 13th term of the arithmetic sequence whose common difference is d=7 and whose first term is a1=-3
timama [110]

Answer:

81

Step-by-step explanation:

the formula for an arithmetic sequence:

aₙ = a₁ + (n-1)d

where aₙ = the nth term

a₁ = the 1st term = -3

n = the term number = 13

d = the common difference = 7

Plugging in those values into the formula to find a₁₃:

a₁₃ = -3 + (13-1)7

= -3 + (12)7

= -3 + 84

= 81

Find the width of rectangle if it's area is (3x^2 + 9xy + 6y^2 ) square centimeters .
Juli2301 [7.4K]
Given:
Length = 3x + 6y cm
Area = 3x² + 9xy + 6y²

Because Area = Width * Length, therefore
Width = Area/Length
           = (3x² + 9xy + 6y²)/(3x + 6y).

Width = Width= \frac{3( x^{2} +3xy+2 y^{2}) }{3(x+2y)}
Width=\frac{(x+y)(x+2y)}{x+2y} =x+y

Answer:  x+y
