Here is your answer
1. (−2^2 − 4 + 13) + (12^2 + 2 − 25)
= (4-4+13)+ (144+2-25)
[Note:- -2^2=(-2×-2)= +4]
= 13+ (146-25)
=13+121
= 134
2. (7^2 + 4 − 26) − (−7^2 − 3 + 15)
= (49+4-26) - (49-3+15)
= 49 +4 -26 -49 +3 -15
= 7-41
= -34

Well if each set had 12 cards. So 18*12 = 216 :D
Answer:
(3x2 + 1) • (4x - 1)
Step-by-step explanation:
Equation at the end of step 1 :
(((12 • (x3)) - 3x2) + 4x) - 1
Equation at the end of step 2 :
(((22•3x3) - 3x2) + 4x) - 1
Checking for a perfect cube :
12x3-3x2+4x-1 is not a perfect cube
Trying to factor by pulling out :
Factoring: 12x3-3x2+4x-1
Thoughtfully split the expression at hand into groups, each group having two terms :
Group 1: 4x-1
Group 2: 12x3-3x2
Pull out from each group separately :
Group 1: (4x-1) • (1)
Group 2: (4x-1) • (3x2)
-------------------
Add up the two groups :
(4x-1) • (3x2+1)
Final result :
(3x2 + 1) • (4x - 1)
Answer:
12 feet
Step-by-step explanation:
w = width
w+2 = length
w(w+2) = 8
w² + 2w - 8 = 0
(w+4)(w-2) = 0
w = -4 <em>exclude because a length cannot be negative</em>
w = 2
length = 2+2 or 4
P = 2(2)+2(4)
P = 4+8 or 12
