Answer:
The expression equal to 2x^(2)+8 is:
First option (2x-4i)(x+2i)
Step-by-step explanation:
If we multiply
(2x-4i)(x+2i)=(2x)(x)+(2x)(2i)-(4i)(x)-4i(2i)
(2x-4i)(x+2i)=2x^(1+1)+4xi-4xi-8i^(1+1)
Simplifying:
(2x-4i)(x+2i)=2x^2-8i^2
and i^2=-1, then:
(2x-4i)(x+2i)=2x^2-8(-1)
Multiplying:
(2x-4i)(x+2i)=2x^2+8
Answer:
273 frogs.
Step-by-step explanation:
The equation of growth in the number of frogs N = 137(1.09)^t where t is the time in years.
The year 2022 is 8 years after 2014 so the prediction for N in 2022 is:
N = 137(1.09)^8 = 273.
Answer:
2³*3²
8*9=72
2³*3²²
8*81=648
gcf of 72 annd 648
72=2*2*2*3*3
648=2*2*2*3*3*3
2*2*2*3*3=72
<h2>the gcf is 72</h2>
