Answer:
The perimeter is 50
Step-by-step explanation:
The original area is LW
The new area is (L-4)(W+3)
These areas are the same
1: (L-4)(W+3)=LW
You are also told that the new figure is a square, hence
2: (L-4)=(W+3)
Equation (2) implies
3: L=W+7
Substitute for L in Equation (1) and solve for W
(W+7-4)(W+3)=(W+7)W
W^2+3W+7W+21-4W-12=W^2+7W
6W+9=7W
W=9
Now use Equation (3) to solve for L
L=16
The perimeter is 2W+2L
P=18+32=50

Write the slope-intercept form of the equation of the line described.
through: (-4, -4), perpendicular to y= -4x-5
PLS SHOW WORK
Answer:
(4-4 = 0) - (4x5 =20) xDDdddAnswer:
[tex]y = \frac{1}{4} x - 3[/tex]
Step-by-step explanation:
Slope-intercept form:
y= mx +c, where m is the gradient and c is the y-intercept.
The product of the gradients of perpendicular lines is -1.
-4m= -1
m= -1 ÷(-4)
m= ¼
Substitute m= ¼ into the equation:
y= ¼x +c
To find the value of c, substitute a pair of coordinates.
y= ¼x +c
When x= -4, y= -4,
-4= ¼( -4) +c
-4= -1 +c
c= -4 +1
c= -3
Thus, the equation of the line is y= ¼x -3.

The question is incomplete. The complete question is :
Basil was shown this enlargement, and he was asked to find the perimeter of the enlarged shape. His work is shown below.
Where, if any, did Basil first make a mistake in his work?
Solution :
Not -- Basil did not make any mistakes in his work. He found out the perimeter of an enlarged shape.
Perimeter is the total measure of the outer lining or the total outer length of the body or the shape. For different shapes, the perimeters will be different. Basil measure the outer length of the body and found out the perimeter.

What is the value of x2+9x+20 when x could be -5, -3 or -6
Answer:
Step-by-step explanation:
You should use a ^ to indicate an exponent. x^2 is the same as x².
x² + 9x + 20
Replace the x with (-5).
(-5)² + 9(-5) + 20 = 25-45+20 = 0
Then do the same with x = (-3):
(-3)² + 9(-3) + 20 = 9 - 27 + 20 = 2
You can do x = (-6)
Find the Difference.
3x + 5 - (2x + 2)

A new car is purchased for 24600 dollars. The value of the car depreciates at 5.5% per year. To the nearest year, how long will it be until the value of the car is 11300 dollars?
Answer:
The number of years until the value of the car is 11300 dollars is 9 years.
Step-by-step explanation:
This can be calculated using the following formula:
Value of the Car = Purchase cost - (Annual depreciation expenses * N) ........ (1)
Where;
N = Number of years until the value of the car is 11300 dollars
Purchase cost = $24,600
Annual depreciation rate = 5.5%
Annual depreciation expenses = $24,600 * 5.5% = $1,353
Value of the car = $11,300
Substituting the value into equation (1) and solve for N, we have:
$11,300 = $24,000 - ($1,353 * N)
$1,353 * N = $24,000 - $11,300
$1,353 * N = $12,700
N = $12,700 / $1,353
N = 9.38654841093865
Rounding to the nearest year as required by the question, we have:
N = 9
Therefore, the number of years until the value of the car is 11300 dollars is 9 years.

What is meant by Trigonometric Identities?Trigonometric Identities are equality conditions that hold for all possible values of the variables in the equation and use trigonometry functions. There exists numerous unique trigonometric identities that relate a triangle's side length and angle.
Sine, cosine, and tangent are the fundamental three operations in trigonometry. The cotangent, secant, and cosecant functions are derived from these three basic functions. On these functions, all trigonometrical notions exists built.
Trigonometric identities are equality conditions in trigonometry that hold for all values of the variables that appear and are defined on both sides of the equivalence. These exists identities that, geometrically speaking, involve certain functions of one or more angles.
