She/he could use 2 12x3 in of wood and 1 4x2 so now we will take all of the numbers and see what we get when we calculat them so when we take the 2 12x3 we will get 72 and then we will add 72 to 4x2 after we multiply them so when we multiply the 4x2 we will get 8 and now will we add 72 to the 8 and we will get a 80 for your answer hope that is the right answer if it is not sorry
A -5/8
B -15/24
because -30/48 divided twice will equal -15/24 which explains the second answer and -15/24 divided by three will equal -5/8

Answer:
C. Q=−31, P = -2
Step-by-step explanation:
2x+Q = Px−31
A. Q = −2 and P=2
2x+Q=Px−31
2x - 2 =2x - 31
0x = -29
0 ≠ -29 : NO SOLUTION
B.Q=31 and P=2
2x+Q=Px−31
2x + 31 = 2x - 31
0x = -62
0 ≠ -62 : NO SOLUTION
C. Q=−31, P = -2
2x+Q=Px−31
2x - 31 = -2x - 31
4x = 0
x = 0 : ONE SOLUTION
D. Q=-31 and P=2
2x+Q=Px−31
2x - 31 = 2x - 31
0x = 0
0 = 0: Infinitely many solutions
Answer:
C. Q=−31, P = -2
