Remember you can do anything to an equation as long as you do it to both sides
expand by foiling or distributing
4x²-19x-5=-43x-41
add 43x to both sides and add 41 to both sides
4x²+24x+36=0
factor
facotr out of 4
4(x²+6x+9)=0
factor inside
what 2 numbers multiply to get 9 and add to get 6?
3 and 3
4(x+3)(x+3)=0
set to 0
x+3=0
x=-3
x=-3 is answer
What is the question? To the problem?
So its asking you to find the gravity on earth relative to the gravity on mars.
Set up an equation to figure out the difference between the two gravities
x=.38
I don't know what constant of proportionality is in this context but a ball on mars would weigh .38 the amount that it does on earth.
Answer:
5 , 7 , 8 represent the side of acute angled triangle
The number of times planet B can fit into planet A is; 1.15× 10⁷ times.
<h3>Volume divisions</h3>
According to the question;
- The volume of planet A is given to be approximately 1.5 x 10¹⁶ km³ and the volume of planet B is 1.3 x 10⁹km³.
From the problem statement above;
It follows that the number of times planet B can fit into A is;
- No. of times = 1.5×10¹⁶/1.3×10⁹.
Hence, N = 1.15× 10⁷ times.
