Answer:
-31
Step-by-step explanation:
-3 to the power of 2 means -3*-3 and since negative multiplied by negative is positive, that will give 9
9 + (2-6)(10)
9+-4(10)
9+ -40
9-40
-31
Answer:
x = 15
Step-by-step explanation:
x + 7 = 22
Subtract 7 from each side
x+7-7 = 22-7
x=15
Answer:
D=-4<0, the equation has no real solutions, it has two imaginary solutions.
Step-by-step explanation:
The quadratic equation
has coefficients
a=1,
b=4,
c=5.
The discriminant D is the expression

Hence,

Since the discriminant is negative, the equation has no real solutions, it has two imaginary solutions.
Answer:
m = 11
Step-by-step explanation:
-2(2 - 4m) = 6(m + 3)
Divide both sides by -2.
2 - 4m = -3(m + 3)
Distribute -3 on the left side.
2 - 4m = -3m - 9
Add 3m to both sides.
2 - m = -9
Subtract 2 from both sides.
-m = -11
Divide both sides by -1.
m = 11
