The algebraic representation of the phrase is 28+5n and when n is 4.2, then the value is 49.
What is algebraic expression?Algebraic expression are the expression which consist the variables, coefficients of variables and constants.
The algebraic expression are used represent the general problem in the mathematical way to solve them.
Steps to write down the simple algebraic expression-
Identify all the factors of the expression.Assume a variable for the changing values.Put a coefficient for the variable, if there is any rate of change of variable.Use constant numbers for the fixed values.
The statement given in the problem is that the twenty-eight plus the product of five and a number.
Let suppose the unknown number is n. Now the product of this number with 5 can be written as,
[tex]5\times n\\5n[/tex]
As, the equation is made when the number 28 is plus in this product. Thus the algebraic representation of the phrase is,
[tex]28+5n[/tex]
When the value of n is 4.2, then the value of this algebraic would be,
[tex]28+5(4.2)\\28+21\\49[/tex]
Hence, the algebraic representation of the phrase is 28+5n and when n is 4.2, then the value is 49.

What is mean by Subtraction?Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.
Now, We know that;
Equation is,
y = bx + a
Where,
b = (xy) - (x) (y) / x² - y²
Here, We have;
x = 12.5
y = 13.17
(xy) = 211.17
Hence, We get;
b = (211.17 - 164.625) / (219.17 - 156.25)
b = 0.74
So, We get;
y = bx + a
13.17 = 0.74 × 12.5 + a
a = 3.92
So,
y = 0.74x + 3.92
y = 0.74 × 18 + 3.92
y = 17.24
Thus, the residual value for x = 18 is,
⇒ 16 - 17.24
⇒ - 1.24

1/5(30)6ABCD is an 8 by 6 rectangle. AC is a diagonal with length 10. Point E is on AC such that BE is perpendicular to AC . What is the length of BE
Answer:
The length of BE is 5 units.
Step-by-step explanation:
ABCD is rectangle
AC is a diagonal and BD is a diagonal too.
Diagonals of rectangle are equal and bisect each other perpendicularly.
So, AE = BE
AE = 1/2 × AC
= 1/2 × 10
= 5
BE = 5
Hence the length of BE is 5 units.
solve:(6 2/5+1 4/5)+315
=) (32/5 + 9/5) + 315

What is the y-intercept of the line that is perpendicular to x-8y = 16 and passes through the
point (2,-2)?
The equation of the line perpendicular to x-8y = 16 and passes through the point (2,-2) is y = -8x + 14.
Linear equationA linear equation is in the form:
y = mx + b
where m is the rate of change (slope) and b is the y intercept.
Given the line is x - 8y = 16:
8y = x - 16
y = x/8 - 2
The slope of the line is 1/8, the slope of the line perpendicular is -8. Hence, since it passes through (2 -2):
y - (-2) = -8(x - 2)
y = -8x + 14
The equation of the line perpendicular to x-8y = 16 and passes through the point (2,-2) is y = -8x + 14.

Given the circle below with secants BCD and FED, find the length of BC.
Round to the nearest tenth if necessary.
If the circle below with secants BCD and FED then length of BC is 7.3cm
What is Circle?A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.
Let BC = x cm
BD=x+6
FD=11+5
From power of a point to circle
BD.CD=DF.ED
(x+6)6=16×5
6x+36=80
Subtract 36 from both sides
6x=80-36
6x=44
Divide both sides by 6
x=7.3
Hence, if the circle below with secants BCD and FED then length of BC is 7.3cm
