A rectangle's length is one greater than five times its breadth. if the perimeter is 38. This will have dimensions of 3 and 16.
What are the dimensions of a rectangle?
There are two dimensions to a rectangle: the length and the width, which are measured in relation to the length. Oval and triangular interiors have only two dimensions.
Since a rectangle is a two-dimensional form, it has two dimensions: length and width. The rectangle's length is its longer side, while its width is its shorter side.
Area only has two dimensions. length into width In some circumstances, we might state that dividing a length by a length produces the area of a square. The methods used to collect area vary depending on the shape.
A dimension, whether it be in terms of length, width, height, or something else, is a solid place to start when looking at a figure's other characteristics. The distance along the figure's outer edge is measured in terms of its perimeter.
Width = x
Length = 5x + 1
2x + 2(5x + 1) = 38
2x + 10x +2 = 38
12x = 38 - 2
x = 36 / 12
x=3
After this, value of x will be putted in 5x + 1.
Therefore, a rectangle's length is one greater than five times its breadth. if the perimeter is 38. This will have dimensions of 3 and 16.

The answer to the problem 5 x (4 + 1) is called a C) product.
Given is an expression 5 x (4+1), we need to tell which mathematical operation dose it shows.
In mathematics, the term "product" refers to the result obtained when two or more numbers are multiplied together.
In this case, the numbers involved are 5 and (4 + 1). The expression (4 + 1) is first evaluated inside the parentheses, which results in 5.
Then, the multiplication is performed: 5 x 5 = 25.
So, the correct answer is C) product.

2^2 = 4
4x + 12x = 66
16x = 66
x = 4.125
Subtract 66 from both sides
2x^2+12x -66 = 66-66
2x^2+12x-66= 0
Use quadratic formula with a=2, b=12 , c= -66

move the 7 over to equate the equation to 0
4x^2 - 12x -7 = 0
(ok now you have a (4), b (-12), and c (-7) here you can either use the quadratic formula to solve it or factor the equation)
to factor it, you have to multiply a and c (4*-7 = -28) and find two numbers that multiply to -28 and add to -12
the numbers are -14 and 2. sub those into the equation in place of b
4x^2 + 2x - 14x - 7 = 0
find the lcd of the first two terms and the last two terms to factor them
2x(2x + 1) - 7(2x+1) = 0
(2x -7) (2x+1) = 0
(x-7/2)(x+1/2) = 0
to find the two x values you need to find what values make the equation equal 0 on both sides.
so x is 7/2 or -1/2
