Answer:

Since Modulus of any real number is a positive Real number.

That is modulus is defined as

| x |= x, if x>0

and -x , if x<0.

=0 , if x=0.

|x|≠ -9,

and , |x|≠-7,

∵ modulus of real number is always Positive.

So, option A |x| = -9

and Option B,|x| = -7

are equation having no solution.

(e+3)(e-5) expanded and simplified

Zarrin [17]

Step-by-step explanation:

$(e + 3)(e - 5) \\ e \times e + e \times ( - 5) + e \times e + e \times 3 \\ { e}^{2} + ( - 5e) + {e}^{2} + 3e \\ {2e}^{2} + ( - 2e)$

In this type of math equation, you have to multiply all members from the first part with the second part.

Expanded:

$e \times e+e \times (-5)+e \times e+e \times 3$

simplified:

${2e}^{2} + ( - 2e)$

Answer:

g = 81.

Step-by-step explanation:

f = k/√g where k is a constant

When f = 12 g = 36, so:

12 = k/√36 = k/6

k = 12*6 = 72.

So the relation is:

f = 72/√g

When f = 8:

8 = 72/√g

8√g = 72

√g = 72/8 = 9

g = 9^2 = 81.
