Answer: 64 ivy stems
Step-by-step explanation:
Answer:
64 ivy stems
To solve this problem we can use rule of three:
Firstly we had 72 ivy stems to use in 18 centerpieces, and know we have 16 centerpieces and want to know how many ivy stems we need to use, so:
18 centerpieces -> 72 ivy stems
16 centerpieces -> X ivy stems
18/16 = 72/X
X = 16*72/18 = 64
He needs to use now 64 ivy stems to maintain the ratio.
First image:
27 / 9 = 3
2.7 / 0.9 = 3
33.3/0.09 = 3
Second image:
168 / 2 = 84
16.8 / 0.2 = 84
1.68 / 0.02 = 84

f(x)=3(x-4)(x+3)
Quadratic function follows the f(x) = ax^2 +bx+c pattern
f(x)=3(x-4)(x+3) after multiplying out is equal to
f(x)=(3x-12)(x+3) = (3x^2+9x-12x-36) = (3x^2-3x-36)
f(x) = (3x^2-3x-36)
where
a = 3
b = -3
c = -36
