Answer:
21n
Step-by-step explanation:
1. triple n = 3(n)
3n
3. multiply 7 = 7(3n) = 21n
Answer:
C
Step-by-step explanation:
10×-28=-280
35-8=27
35×(-8)=-280
10x²+27x-28
=10x²+(35-8) x-28
=10x²+35x-8x-28
=5x(2x+7)-4(2x+7)
=(2x+7)(5x-4)
From the graph given
For f(x), where x = 3, on the graph f(3) is

For g(x), where x = 3, on the graph g(3) is

Hence,

The answer is the second option
Answer:
Missing constant: 100
Step-by-step explanation:
perfect square (a - b)^2 = a^2 - 2ab + b^2
In this case
20x = 2 * x * 10
and
10^2 = 100
so
(x - 10)^2 = x^2 - 20x + 100
