Answer:
6 + 6m -9
=> (6 - 9) + 6m
=> -3 + 6m
If my answer helped, kindly mark me as the brainliest!!
Thank You!!
We can’t because you didn’t give us any other information other than she has 230 coins
SQ = square root
329 = 20 * SQ (273+ t)
Do the inverse of everything on the left
Divide by 20
Square your answer (329/20)
and subtract 273 from it
((329/20)^2)-273 = t
the temperature according to my calculations was <span>-2.3975 degrees
The nearest degree, if my math is correct was -2 degrees.
I'm not sure how to graph the equation, or I can't graph it for you, rather. Try Desmos if you need to graph it.

Step 4 :
6n3 - 16n2
Simplify ——————————
15n2 - 40n
Step 5 :
Pulling out like terms :
5.1 Pull out like factors :
6n3 - 16n2 = 2n2 • (3n - 8)
Step 6 :
Pulling out like terms :
6.1 Pull out like factors :
15n2 - 40n = 5n • (3n - 8)
Canceling Out :
6.2 Cancel out (3n - 8) which appears on both sides of the fraction line.
Dividing exponential expressions :
6.3 n2 divided by n1 = n(2 - 1) = n1 = n

Completing the square is done as follows:<span>
1. Write
the equation in a way that the constants are in the right side while the terms
with x are on the left.
9x2 +54x = 7
2.
Make sure that the coefficient of the x^2 term is 1.
9(x2 + 6x) = 7
<span>3.
Adding a term to both sides that
will complete the square in the left side. This is done by dividing the
coefficient of the x term by 2 and squaring it. Note: The same amount should be
added to the right side to balance the equation.</span>
9(x2 + 6x + 9) = 7 + 81
<span>9(x+3)^2 = 88</span></span>
