Answer:
Substitute the known values into the formula: 140 = 7(w)(5).
Solve for the unknown: w = 4 m.
Check:
140 = 7(w)(5) => w = 140/(5 x 7) = 140/35 = 4. => Correct.
Substitute the known values into the formula:
7 = 140(w)(5).
Solve for the unknown: w = 7 m.
Check:
7 = 140(w)(5) => w = 7/(140 x 5) = 7/700 = 1/100. => Incorrect.
Substitute the known values into the formula:
5 = 7(w)(140).
Solve for the unknown: w = 2 m.
Check: 5 = 7(w)(140) => w = 5/(7 x 140) = 5/840 = 1/168. => Incorrect.
Hope this helps!

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.
