-11a^2+1ab+4b^2; P-Q would mean you rearrange the equation to where (-4a^2-2ab+9b^2)-(7a^2-3ab+5b^2). Don't forget to distribute the negative for Q since you plugged it into a variable.

-4a^2-2ab+9b^2-7a^2+3ab-5b^2

Add/Subtract like terms

-11a^2+1ab+4b^2

X + p = q

expeople1 [14]

X=q-p
What you have to do is to rearrange the formula
x+p=q
All you have to do is to move “+q” to the other side of the formula. Doing so you also have to change the sign from “+” to “-“ so that your equation could be balanced
Hope this helps!!!!

Ecosia is one solution to climate change. Why?

balu736 [363]

Answer:

Step-by-step explanation:

NATURAL DISASTERS ARE UP… dramatically

CO2 concentrations in our atmosphere are up … dramatically

TEMPERATURES are up … dramatically

"There is no need to add additional taxes to combat climate change. The best bet is simply QUIT SUBSIDIZING those human activities which causing AGW.

World-wide, Fossil Fuels & industries suck up subsidy Dollars. SUCK UP roughly 6.5% of GDP ... TRILLIONS of DOLLARS in subsidies / supports (non taxable supports & subsidies!) ... In most cases the newer more modern energy and agricultural systems are more profitable and less damaging to the environment already.

So there is no need to tax people to subsidize those things harming the environment, then taxing us again to penalize those same ones we just subsidized!

A house divided against itself cannot stand. -Lincoln (paraphrasing the Bible)

It is time for a strong political leader to take charge and end this deadlock. ... We could either reduce taxes and let the new technologies out compete the obsolete systems we depend on now, or we could keep taxes the same and simply redirect the subsidies we use for fossil fuels and destructive industrialized agriculture towards modern sustainable systems instead. The one thing that won’t work is keep the tax and spend schemes the Neo-Luddites have made for themselves now, and also add even more tax and spend schemes for their competing new technologies too!

Yes that’s right, the top two causes for global warming are heavily subsidized.[1][2][3][4] It is literally insanity. ...

hope this helps have a great morning❤️
