Answer:
-x² + 5x
Step-by-step explanation:
Distribute -x to all terms within the parenthesis. Note that when multiplying a negative variable and a positive variable, the result is a negative variable. Also note that when multiplying a negative variable with a negative number, the result is a positive.
(-x)(x) = -x²
(-x)(-5) = 5x
-x² + 5x is your answer.

262,144 feet squared
This seems like a big number but area length times width. If the coaster is square then all sides are the same so the length and width are both 512 feet. This means you multiply 512 and 512. With that you get 262,144 feet squared.
Answer
:we are told that every year the temperature rises by 0.08degrees Centigrade,
So the difference between margin of error and the increase is much higher
That is
0.15-0.08=0.07
But remember Margin of error=Critical value *Standard deviation of population
And it is a quantity that measures accuracy
So the counter argument is that this is still an increase and it should be considered.

Answer:
13+3g=2g
We simplify the equation to the form, which is simple to understand
13+3g=2g
We move all terms containing g to the left and all other terms to the right.
+3g-2g=-13
We simplify left and right side of the equation.
+1g=-13
We divide both sides of the equation by 1 to get g.
g=-13
Step-by-step explanation:

We divide both sides of the equation by 1 to get g.
g=-13
When you multiply exponents, you keep the number (4) the same and you add the exponents. So:
4^2*4^5= 4^7
Louis is correct.
I hope this helps!
