Now there is a square city of unknown size with a gate at the center of each side. There is a tree 20 b from the north gate. Tha
Brums [2.3K]

Answer:

The length of each side of the city is 250b

Step-by-step explanation:

Given

a = 20 --- tree distance from north gate

b =14 --- movement from south gate

c = 1775 --- movement in west direction from (b)

See attachment for illustration

Required

Find x

To do this, we have:

\triangle ADE \sim \triangle ACB --- similar triangles

So, we have the following equivalent ratios

AE:DE = AB:CB

Where:

AE = 20\\ DE = x/2 \\ AB = 20 + x + 14 \\ CB = 1775

Substitute these in the above equation

20:x/2 = 20 + x + 14: 1775

20:x/2 = x + 34: 1775

Express as fraction

\frac{20}{x/2} = \frac{x + 34}{1775}

\frac{40}{x} = \frac{x + 34}{1775}

Cross multiply

x *(x + 34) = 1775 * 40

Open bracket

x^2 + 34x = 71000

Rewrite as:

x^2 + 34x - 71000 = 0

Expand

x^2 + 284x -250x - 71000 = 0

Factorize

x(x + 284) -250(x + 284)= 0

Factor out x + 284

(x - 250)(x + 284)= 0

Split

x - 250 = 0 \ or\ x + 284= 0

Solve for x

x = 250 \ or\ x =- 284

x can't be negative;

So:

x = 250

Write the compound inequality shown by the graph.<br> 20. 2QHHH<br> UNIT 4
belka [17]

Answer:

x ≥ 9 and x < 5

Step-by-step explanation:

See the line graph of a compound inequality shown in the attached photo.  

Inequality has two parts. The right-hand part is shown by an arrow that is more than 9 and including 9.

So, the equation of inequality for this part is x ≥ 9.

Again, the left-hand part of the inequality graph shows another arrow which is less than 5 but not including 5.

So, the equation of inequality for this part is x < 5

Therefore, compound inequality is x ≥ 9 and x < 5 (Answer)
