If the first of three consecutive integers is subtracted from 138, the result is the sum of the second and third. What are the i
otez555 [7]

Answer:

First Integer = n = 45

Second Integer = n+1 = 45 + 1 = 46

And Third Integer = n+ 2 = 45 +2 = 47

Step-by-step explanation:

Let First integer = n

Second Integer = n+1

Third Integer = n+2

According to the question given (If the first of three consecutive integers is subtracted from 138, the result is the sum of the second and third) the equation will be:

138 - n = (n+1) + (n+2)

Solving the equation:

138 - n = n+1+n+2

138 - n = 2n+3

138 - 3 =2n +n

135 = 3n

135/3 = n

=> n= 45

So, First Integer = n = 45

Second Integer = n+1 = 45 + 1 = 46

And Third Integer = n+ 2 = 45 +2 = 47

Answer 1: For the Parallelogram inside the rectangle the area = 48

Rectangle = 275     275+48 = 323

Answer 2: For the answer for the square inside the parallelogram = 36

The answer to the parallelogram = 120     120+36 = 156

Step-by-step explanation: #1: A = bh = 12 · 4 = 48

A = wl = 11 · 25 = 275

#2: A = a2 = 62 = 36

A = bh = 15 · 8 = 120

Sorry if u didn't have to add im not to good at this ;(

Hope that helped though!
