Answer:
14.6°C
Step-by-step explanation:
Method 1
Higher value - lower value
12.2°C - (-2.4°C) *two negatives make a positive
12.2 + 2.4
14.6°C
Method 2
-2.4°C to 0°C = 2.4 increase (+2.4°C)
0°C to 12.2°C = 12.2 increase (+12.2°C)
Total change = 12.2 + 2.4= 14.6°C

Answer:
The answer is A
Step-by-step explanation:
A because it's simply adding by 4 on the right-hand side.
The dimensions of the prism can be 2x, 2x+3 and x+6.
We first factor out the GCF of the trinomial. The GCF of the coefficients is 2. Each term has an x in common as well, so the GCF is 2x.
Factoring out the 2x, we have
2x(2x²+15x+18).
To factor the remaining trinomial, we find factors of 2*18=36 that sum to 15. 12*3 = 36 and 12+3 = 15. We split up 15x into 12x and 3x:
2x(2x²+12x+3x+18)
Now we group together the first two terms in parentheses and the last two:
2x((2x²+12x)+(3x+18))
Factor out the GCF of the first group:
2x(2x(x+6)+(3x+18))
Factor out the GCF of the second group:
2x(2x(x+6)+3(x+6))
Factoring out what these have in common,
2x(x+6)(2x+3)
