Answer:
9n+18(2n-6)+13
Step-by-step explanation:
First, use distributive property to eliminate the parenthesis:
9n + 18(2n -6) + 13
9n + 36n - 108 + 13
Next, combine like terms:
9n + 36n - 108 + 13
45n - 108 + 13
45n + 121
Hope this helps!!

Answer:
Step-by-step explanation:
Given is a table of x, f(x) as below
x 1 3 4 6 7 9 10
f(x) 4 8 6 10 10 12 16
Mid pt 6 7 8 10 11 14
width of
interval 2 1 2 1 2 1
dA1 12 7 16 10 22 14
area = area of all rectangles= 81 sq units.
Easy
quadratic means 2nd degree
means highest power of exponent is 2
so like x^2
first one
we have 3x^3, that is 3rd degree,nope
2nd one
we have 8x^4, nope, that is 4th degree
3rd one
we have -x^2, yep
4th one, we have 9x^4, that is 4th degree
answer is 3rd one or p(x)=-5x-x^2
Answer:
Step-by-step explanation:
28 kg + 750 g = 28*1000 + 750
28000 + 750
= 28750 g
Number of sack = Total quantity of sugar ÷ quantity of sugar in a sack
= 28750 ÷ 500
= 57 sacks
Step-by-step answer:
A line with slope (or gradient) m, passing through a point (x0,y0) can be represented by the equation:
(y-y0) = m(x-x0) ......................(1)
Here,
(x0,y0) = (1,7), and
slope/gradient = -2
Substitute values into (1) above gives
(y-7)=2(x-1)
Expand and simplify
y-7 = 2x-2
y =2x -2 + 7
y=2x+5
is the final answer.
