Half of 6 is 3
Half of 8 is 4
so it will be 3 in by 4 in.
Pretty sure it’s 4 idk tho this is a tough one. Hahahaha
Pretty sure this one is B. that’s what makes most sense.
The numbers in pie are 3.14159
Answer:
x^3+5x^2+16x+80
Step-by-step explanation:
You know that you can write your polynom this way : (x-r1)(x-r2)(x-r3) with r1,r2 and r3 the roots so you get :
(x+5)(x+4i)(x-4i)
Simplify (x+4i)(x-4i) with the formula (a-b)(a+b)=a²-b²
so you have (x^2+16)=(x+4i)(x-4i)
Your polynom looks like this :
(x^2+16)(x+5) just expand it
and you get x^3+5x^2+16x+80
