What is the question you have?
Area of rectangle is the multiplication between the sides.
The first rectangle:
A = (2x + 5) . (3x - 2)
A = 2x . 3x - 2 . 2x + 5 . 3x - 2 . 5
A = 6x² - 4x + 15x - 10
A = 6x² + 11x - 10
The second rectangle:
A = (5y + 5) . (2y - 3)
A = 5y . 2y - 3 . 5y + 5 . 2y - 3 . 5
A = 10y² - 15y + 10y - 15
A = 10y² - 5y - 15
Hello :
-5^4+4n^2-n+5 : the coefficient of n^2 is : 4<span>
7n^4-5n^3-9n^2+3n+2 : </span><span>he coefficient of n^2 is :-9</span>
we are given
x-intercept is 3
so,
a=3
y-intercept is 2
b=2
now, we can intercept formula of line
now, we can plug
a=3 and b=2
now, we will get rid of denominators
so, we can multiply both sides by 6
we can also write it as
so, option-D..................Answer
Given:
1st term = 11
common difference = 6
f(x) = 11 + 6(x - 1)
f(18) = 11 + 6(18-1)
f(18) = 11 + 6(17)
f(18) = 11 + 102
f(18) = 113 number of seats in row 18.
