Answer:
-5
Step-by-step explanation:
3x²y + xy²
Let x = -1/2 and y = 4
3(-1/2)^2 (4) + (-1/2) (4)^2
Exponents first
3(1/4) (4) + (-1/2) 16
Multiply
3 - 8
Subtract
-5
Answer:
x = 3, 4, 5
Step-by-step explanation:
Solving the inequality
5x + 2 > 12 ( subtract 2 from both sides )
5x > 10 ( divide both sides by 5 )
x > 2
Thus the only values from the given set which make the inequality true are
x = 3, 4, 5
X2 - 25 = 0
Add 25 on each side.
x2 = 25
Divide by 2 on each side.
x = 12.5
