I'm just going to give the answers snce so many questions
1. 2
2. 2/(m^2)
3. 1/(16x^8)
4. 3x^4
steps one: the one that starts with squareing both sides (√5x-9)^2=4^2)
23. x=9
24. 0
last graph one: third one (one that starts at 2 up from the origin)
Answer:
2x^3 + 6x^2
Step-by-step explanation:
Volumen = area * height
You already had the area which is:
x^2 + 3x
and the heigth is 2x
Volumen = (x^2 + 3x)* 2x
Volumen = 2x^3 + 6x^2
A rectangle with two sides that are 2 units long and two sides that are 4 units long fits those specifications.
First you want to get x by it’s self so you need to get ride of your 5 so you subtract 5 on both sides leaving you with -2 and -5 on the same side then you combine those two number to get -7 now to get your x all you have to do is divide both sides by -7 since your x is -7 once once your x is now by its self but on the other side -7 divided by -7 equals 1 bc 7 goes into 7 once and it turns positive because anytime you divide an negative number by a negative number it turns into a positive number so your answer over all is 1=x
