The lenght of a regtangle is four meters longer than its breath x. which equation below would give its area? niel is 6 years old than sean, who is h years old, and nikki is twice sean's age . the sum of their ages is 86 .which equation below show this information? the sum of 3 consecutive 177 .find the largest of the numbers

Problem 1

x = width (or breadth)

x+4 = length

area = x*(x+4)

area = x^2+4x

Problem 2

h = Sean's age

h+6 = Niel's age

2(h+6) = 2h+12 = Nikki's age

The sum of their ages is 86, so,

h+(h+6)+(2h+12) = 86

Problem 3

x = first number

x+1 = next number after x

x+2 = largest number (after x+1)

all three numbers are whole numbers

add up the three expressions, set it equal to 177, then solve for x

x+(x+1)+(x+2) = 177

3x+3 = 177

3x+3-3 = 177-3

3x = 174

3x/3 = 174/3

x = 58

x+1 = 58+1 = 59

x+2 = 58+2 = 60

The largest of the three numbers is 60.
