The tile along the edge of a triangular community pool needs to be replaced. Which expression represents the total perimeter of
topjm [15]

The total perimeter of the pool edge \boxed{12{x^2} + 15}.Option A is correct.

Further Explanation:

The formula of area of square can be expressed as follows,

{\text{Area}} = \dfrac{1}{2} \times \left( b \right) \times \left( h \right)

The formula of perimeter of the triangle can be expressed as follows,

\boxed{{\text{Perimeter}} = 3 \times s}

Here, s represents the side of square.

Given:

The options are as follows,

A. {12x^2} + 15

B. {20x^2} + 25

C. {12x^2} + 8x +25

D. {24x^2} + 16x + 50

Explanation:

Option A is {12x^2} + 15.

12 and 15 are the multiple of 3.

\begin{aligned}{\text{Perimeter}} &= 12{x^2} + 15\\&= 3\left( {4{x^2} + 5} \right)\\\end{aligned}

Therefore, the perimeter of the pool is {12x^2} + 15.

The total perimeter of the pool edge \boxed{12{x^2} + 15}.Option A is correct.

Option A is correct.

Option B is not correct.

Option C is not correct.

Option D is not correct.

Q1.

Angle BAD is adjacent to angle CAD

which means they are equal

so angle BAD = 26 degrees


Q2.

Angel BAC = the sum of angles BAD and CAD

because they are adjacent angles

To find the angles we solve the equations

9x-5 = 3x+7

9x-3x = 7+5

6x = 12

x = 12/6

x = 6

Question 14. When solving the equation -14 = 7x + 6 what will the next stage of your working be?
mr_godi [17]

Answer:

You would subtract 6 from each side.

Step-by-step explanation:

- 14 = 7x + 6

Subtract 6 from each side:

- 14 - 6 = 7x + 6 - 6

7x = - 20

Divide each side by 7:

7x ÷ 7 = - 20 ÷ 7

x = 2 and 6/7
