Answer:
It's 243 sq in.
Step-by-step explanation:
You have to multiply the 18 since it the the actual height and 13.5 because it is the width while the 19 is just some random number that has nothing to do with anything.
The answer is a)
<span>0 imaginary; 3 real
proof
f(3)= = 27-20.9+123.3-216= 216-216=0
so f(x)=(x-3)(ax²+bx+c)=0
after doing euclidean division </span>
<span>ax²+bx+c= (x-8)(x-9)=x²-17x+72
and </span><span><span>x²-17x+72</span> = (x-8)(x-9)
so f(x)=(x-3)</span><span><span>(x-8)(x-9)</span>
f(8)= 8^3-20*64+123*8-216=216-216=0
f(9)=9^3-20*81+123*9-216=0

Answer:
5x-1
Step-by-step explanation:
8x-3(x+1)-4
{open the brackets}3x-3
8x-3x-3-4
5x+(-7), which is 5x-7
Support:
10% of 20 < 20% of 100 [2 < 20]
Refute:
10% of 100 > 20% of 20 [10 > 4]
