Answer:
2.3 by 10^7
Step-by-step explanation:
We want this rewritten in the form 2.3*10^n.
To get the decimal point in 23,000,000 between the 2 and 3, we must move it 7 places to the left, and then compensate for this by multiplying 2.3 by 10^7.
Volume (rectangular prism)=long x wide x hight
Data:
volume=2880 in³
Long=24 in
wide=10 in.
2880 in³=24 in * 10 in * higth
2880 in³=240 in² * hitgh
higth=2880 in³ / 240 in²
higth=12 in
Answer: the higth of the aquarium is 12 in.
The answer
let be
A1 = (2x^4-3x^3+2x+4)-(-x^4-3x^3+4x^2+x+3) =
= 2x^4-3x^3+2x+4 +x^4 +3x^3- 4x^2- x-3
A1= 6x^4 -2x² +x +1
and
A2= 5x^4-2x^3+3x^2+3x-4-(2x^4-2x^3+7x^2+2x-5)
= 5x^4-2x^3+3x^2+3x-4-2x^4+2x^3-7x^2-2x+5
A2<span>= 3x^4-4x²+x+1
A1 is not equivalent to A2
so the answer is </span><span>B. False </span>
