Answer:

(4a - 5)(4a + 5)

Step-by-step explanation:

Assuming you require to factor the expression

Given

16a² - 25 ← is a difference of squares and factors in general as

a² - b² = (a - b)(a + b)

16a² - 25

= (4a)² - 5²

= (4a - 5)(4a + 5) ← in factored form

Ms. Pendleton’s bedroom is a shape of a rectangle. The width of the room is 16 feet and length is four more feet than the width.

QveST [7]

Answer:

The answer to your question is Perimeter = 64 ft

Step-by-step explanation:

Data

width = 16 ft

length = width + 4 ft

Perimeter = ?

Process

1.- Calculate the length

Length = 14 + 4 = 18 ft

2.- Look for the formula of the perimeter

Perimeter = 2(length) + 2(width)

3.- Substitution

Perimeter = 2(18) + 2(14)

4.- Simplification

Perimeter = 36 + 28

5.- Result

Perimeter = 64 ft

If ∆GFE ~ ∆CBE, find the value of x

saw5 [17]

2/5 x 60 = 24
2/5 x (4x - 1) = x+5
8x - 2 = 5x + 25
3x = 27
x = 9
The value of x is 9

PLEASE HELP!!! Write the equation of a line that goes through the point (6, 3) and is perpendicular to the line y = 4x + 1.

Tpy6a [65]

For this case we have that by definition, the equation of a line in the point-slope form is given by:

$y-y_ {0} = m (x-x_ {0})$

Where:

m: It is the slope of the line and $(x_ {0}, y_ {0})$ is a point through which the line passes.

We have the following equation of the slope-intersection form:

$y = 4x + 1$

Where the slope is $m = 4$

By definition, if two lines are perpendicular then the product of their slopes is -1.

Thus, a perpendicular line will have a slope:

$m_ {2} = \frac {-1} {m_ {1}}\\m_ {2} = \frac {-1} {4}\\m_ {2} = - \frac {1} {4}$

Thus, the equation will be of the form:

$y-y_ {0} = - \frac {1} {4} (x-x_ {0})$

Finally we substitute the given point and we have:

$y-3 = - \frac {1} {4} (x-6)$

Answer:

Option B
