Answer:
X > -3, 0.28, 4
Step-by-step explanation:
x - 7 > -12 - To solve add 7 to both sides
x > -5 Which means every number GREATER but not EQUAL to 5 will count as a solution to the equation, therefore 5 is not a correct answer. -3 is greater then -5, and any positive number is greater then any negative number.
Therefore the Correct Answer is : -3. 0.28, 4
surface area = (2)(5)(13)+(13)(10)+(12)(10)
3,6,-2
a+2a+b = 7
2a^2b = -36
a*2a + ab + 2ab = 0
or, a(2a+3b) = 0
so, b = -2a/3
Solve those and you find 3,6,-2
