The possible values of x according to the give. equation are; 0, ±√3i, ±2i, i, -1.

<h3>What are the possible values of x?</h3>

The possible values of x in the equation given in the task content represent the zeroes of the equation and can be determined as follows;

(x²+3) (x³+4x) (x²+x-i-xi) = 0.

Hence, by further factorisation; we have;

x(x²+3) (x²+4) (x-i) (x+1) = 0.

The possible values of x are therefore;

x = 0;

x²+3 = 0; x = ±√3i

x² +4 = 0; x = ±2i

x -i = 0; x = i.

x +1 = 0; x = -1

the present age of prisca and Ashmaal are in ratio 2:3 . After 4 yrs the ratio of their ages will be 4:5 the present age of pris
Solnce55 [7]

Answer:

he Present age of Prisca will be 4 years  .

Step-by-step explanation:

Given as :

The ratio of present age of Prisca and Ashmaal = 2 : 3

Let The present age of Prisca = 2 x  years

Let The present age of Ashmaal = 3 x  years

After 4 years , the ratio of present age = 4 : 5

i.e \frac{ 2 x + 4}{3 x + 4} = \frac{4}{5}

Or,  5 × (2 x + 4) = 4 × (3 x + 4)

Or, 10 x + 20 = 12 x + 16

Or, 12 x - 10 x = 20 - 16

Or, 2 x = 4

∴  x = \frac{4}{2}

i.e x = 2

So, The present age of Prisca = 2 x = 2 × 2 = 4 years

And The present age of Ashmaal = 3 x = 3 × 2 = 6 years

Hence, The Present age of Prisca will be 4 years  . Answer

Answer:

-36

Step-by-step explanation:

plug in the letters for the numbers, then you get, -8 - 25 - 3.  -8 - 25 is -33, then you subtract that to 3. so it should look like, -33 - 3.  then simplified even more is -36.

A 14- inch pepperoni pizza is sliced into 8 equal pieces. One slice contained 352 calories. Write and solve a division equation
tankabanditka [31]

<em><u>Division equation is:</u></em>

\frac{c}{8} = 352

There are 2816 calories in whole pizza

<em><u>Solution:</u></em>

Given that,

A 14- inch pepperoni pizza is sliced into 8 equal pieces

One slice contained 352 calories

Therefore,

1 slice = 352 calories

Let "c" be the calories

Given that there are 8 equal pieces

<em><u>Therefore, calories in 8 pieces are:</u></em>

Calories in 8 pieces = 8 x calories in 1 piece

c = 8 \times 352

Thus the division equation is:

\frac{c}{8} = 352

Therefore,

c = 352 \times 8 = 2816

Thus there are 2816 calories in whole pizza
