The equations presented in the choices above are all derived from the Pythagorean theorem. This states that the sum of the squares of the two shorter sides is equal to the square of the longest side which is also referred to as the hypotenuse. 

If the sum of the squares of the shorter sides is smaller compared to the square of the hypotenuse then, the triangle is OBTUSE. The answer therefore to this item is letter A.

Answers And Explanations:

Question 1.

Pulling out like terms :

1.1     Pull out like factors :

  12y - 10  =   2 • (6y - 5)  

Equation at the end of step  1  :

  Divide both sides by  2  

 

 Divide both sides by  6  

 y-(5/6)  > 0

Add  5/6  to both sides

y > 5/6.

Therefore, y = 5/6

__________________________________

Question 2.

To make fractions improper with whole numbers, you must <u>multiply the Denominator by the whole number, then add the Numerator to the Product.</u>

<u></u>

First we multiply 32 by 5.

32 x 5 = 160.

Then we add the Numerator which is 1.

160 + 1 = 161, then we put it over the Denominator, your final answer is 161/5.

Therefore, 161/5 is your final answer.

Solving for x, please answer quickly D:
Tema [17]
  • We know, sum of all angles of a triangle is 180°.
  • Therefore, by the problem

72 + 64 + (4x+20) = 180

or, 156 + 4x = 180

or, 4x = 180 - 156

or, 4x = 24

or, x = 24 ÷ 4 = 6
