Six less than one-third of the sum of a number and four is negative two.

Helga [31]

1/3(n + 4) - 6 = -2 <== ur equation
1/3n + 4/3 - 6 = -2 ...multiply by 3
n + 4 - 18 = - 6
n - 14 = -6
n = -6 + 14

The area of a rectangle is 56 cm. The length is 2 cm more than x and the width is 5 cm less than

AURORKA [14]

The value of x is 6 cm.

Step-by-step explanation:

Given,

Area of rectangle = 56 cm

Length of rectangle = x+2

Width of rectangle = 2x-5

Area = Length * Width

$56=(x+2)(2x-5)\\56=2x^2-x-10\\0=2x^2-x-10-56\\2x^2-x-66=0$

Factorizing

$2x^2+11x-12x-66=0\\x(2x+11)-6(2x+11)=0\\(2x+11)(x-6)=0$

Either,

2x+11 = 0 => 2x=-11

Or,

x-6=0 => x=6

As x is added to dimension, it cannot be negative.

Therefore,

The value of x is 6 cm.
