Please procedure and solution <br><br>2 x |-6|-3 x |2|+|-14|=​
lora16 [44]

Applying the rule of modulus for given values, the expression will result to 20.

<h3>What is Modulus or Absolute Values</h3>

The modulus of a value for example |a|=a if a is greater than or equal to zero

and also

|a|=-a if a is less than zero

In the expression given; the modulus of -6 written as

|-6|=-(-6) this is because the value is less than zero

The modulus of 2 written as; |2|=2 this is because the value is greater than zero. and;

|The modulus of -14 written as; |-14|= -(-14) since the value is less than zero.

Hence, we can rewrite the expression as;

we deal with multiplication first following the rules of BODMAS

2×-(-6)-3×2+[-(-14)]

2×6-6+14

and thus adding values

12+14-6

and finally we subtract;

26-6

which will results to the solution of 20.

Find the values for x and y
USPshnik [31]

Answer:

x = 55

y = 70

Step-by-step explanation:

Since all three sides are equal, as indicated by the lines on the sides, all three angles are equal

Since a triangle is equal to 180 degrees

180/3 = 60

Each angle is 60 degrees

x+5 = 60

Subtract 5 from each side

x +5-5 = 60-5

x = 55

y-10= 60

y-10+10 = 60+10

y= 70
