The value of x is 10
Its hard to explain
Answer:
The first step of factorising an expression is to 'take out' any common factors which the terms have. So if you were asked to factorise x² + x, since x goes into both terms, you would write x(x + 1) . This video shows you how to solve a quadratic equation by factoring.

Answer:
A/ 3.14a=b
Step-by-step explanation:
A=3.14ab
Divide each side by 3.14 a to isolate b
A/ 3.14a=3.14ab/3.14a
A/ 3.14a=b
Answer:
Step-by-step explanation:
Looking at the scenario, a right angle triangle is formed.
The length of the pole represents the hypotenuse of the right angle triangle.
The distance from the top of the pole to the ground represents the opposite side of the right angle triangle.
To determine the angle formed by the pole and the ground, we would apply we would apply the Sine trigonometric ratio.
Sin θ = opposite side/hypotenuse. Therefore,
Sin θ = 15/18 = 0.833
θ = Sin^-1(0.833)
θ = 56.4°
