Step-by-step explanation:
Answer:
It is the right-angled triangle.
Step-by-step explanation:
According to the Pythagorean theorem, , which c is the longest side of the triangle.
So, if the triangle is right angle.
∵LHS=RHS
∴It is a right-angled triangle.
Answer:
<h2>
</h2>
Step-by-step explanation:
Divide both sides of the equation by 3
Write 7x as a difference
Factor out 3x from the expression
Factor out -4 from the expression
Factor out 2x + 5 from the expression
When the product of factors equals 0 , at least one factor is 0
Solve the equation for X
Move constant to R.H.S and change its sign
Calculate the difference
Divide both sides of the equation by 2
Calculate
Again,
Move constant to RHS and change its sign
Calculate the sum
divide both sides of the equation by 3
Calculate
Hope this helps..
