Answer:
Step-by-step explanation:
the answer is 3
Get the variable on one side and the numbers on the opposite side.
5x + 12 = x - 8
Let's get rid of that x on the right-hand side of the equation.
We can do this subtracting x from each side of the equation.
(5x - x) + 12 = (x - x) - 8 =
4x + 12 = -8
Let's take out the 12 so that the 4x can be alone.
We can do that by subtracting 12 from each side
4x + (12 - 12) = -8 - 12 =
4x = -20
And finally, divide the both sides by the coefficient of the 4x term. Which is 4.
4x / 4 = -20 / 4 =
x = -5
So, x is equal to -5.
Answer:
1/(16r²)

r`²/16r° = r`²/16 = 1/(16r²)
Answer: it can have at most one right angle but at most, 2 acute angles
Step-by-step explanation:
A triangle is a shape bounded by 3 sides and it has three angles.
The sum of the angles is 180 degrees
A right angle is 90 degrees. So a tight angled triangle has one of the angles equal to 90 degrees.
An acute angle is an angle lesser than 90 degrees.
An obtuse angle is an angle greater than 90 degrees but lesser than 180 degrees. Assuming we have a right angle triangle.
So a triangle can have at most one right angle while a triangle can have more than one acute angle. For example, a right angled triangle has two acute angles. So also, a triangle containing an obtuse angle has two acute angles
