Equation solving

2 (x +2) = x - 4
2 x + 4 = x - 4
2 x - x = -4 - 4
 x = - 8

Answer =  x = -8

2(x + 2) = x - 4

2x + 4 = x - 4

2x - x = -4 - 4

x = -8

Solution: x = -8

What is the solution set for x2+25=0
Masja [62]

Step-by-step explanation:

{x}^{2}  + 25 = 0 \\  \therefore {x}^{2}  =  - 25 \\ \therefore {x}  =  \sqrt{ - 25}  \\  \therefore {x}  =   \pm\sqrt{ - 1 \times 25}  \\ \therefore {x}  = \pm  \sqrt{  25}  \times  \sqrt{ - 1}  \\ \therefore {x}  =  \pm5 \: i  \\ \therefore {x}  = \{ - 5i, \:  \: 5i \} \: \\  is \: the \: solution \: set.

A park has a 3m tall tetherball pole, and a 6.8m tall flagpole. The lengths of their shadows are proportional to their heights.
vlada-n [284]

Complete question is;

A park has a 3 meter tall tether ball pole and a 6.8 m tall flagpole. The lengths of their shadows are proportional to their heights.

Which of the following could be the lengths of the shadows?

Choose 2 answers from the options attached.

Answer:

Options B & D

Step-by-step explanation:

From the question, the proportional relationship between the height and shadow length is a direct proportionality. This means that an increase in the height, leads to an increase in the length of shadow and vice versa. Thus, the height to shadow length ratio is a constant.

Now, if we use x and y to denote length of shadow of tether ball pole and length of flagpole receptively, we will have;

3/x = 6.8/y

Let's make y the subject.

y = 6.8x/3

Looking at the options;

Option A: When x = 1.35 m, we have;

y = (6.8 × 1.35)/3 = 3.06 m

For Option B:

When x = 1.8 m,

y= (6.8 × 1.8)/3 = 4.08 m

For Option C:

When x= 3.75 m,

y = (6.8 × 3.75)/3 = 8.5 m

For option D:

When x = 0.6

y = (6.8 × 0.6)/3 = 1.36 m

For option E;

When x = 2,

y = (6.8 × 2)/3 = 4.533 m

From our calculations, the only values of y that correspond with the given value of y in the options are Options B & D
