The perimeter of a rectangle is 160. The length of the rectangle is 4 times greater than the width. What is the area of this rectangle?
The area of this rectangle is 1024 square units.
To solve this problem, we'll need to use the given information about the perimeter and the relationship between the length and width to find the dimensions of the rectangle. Then, we can determine the area.
First, let's use the formula for the perimeter of a rectangle: P = 2L + 2W, where P is the perimeter, L is the length, and W is the width. We know that P = 160 and L = 4W.
Now, let's substitute these values into the formula:
160 = 2(4W) + 2W
Next, we can simplify the equation:
160 = 8W + 2W
160 = 10W
Now, let's solve for W:
W = 16
With the width found, we can now determine the length using L = 4W:
L = 4(16)
L = 64
Finally, we can calculate the area using the formula A = L * W:
A = 64 * 16
A = 1024
The area of this rectangle is 1024 square units.

If he puts away 10% of his $32,000 salary every year, The total of his 401(k) be in 10 years is: a. $67,266.16.
401(k) in 10 yearsFirst step
Contribution=(10% ×$32,000)+ 50% from employer
Contribution=$3,200+ ($3,200×50%)
Contribution=$3,200+$1,600
Contribution=$4,800
Second step
Future value= 4800 (1 + 0.073)^10 – 1/ 0.073
Future value= 4800 (1 .073)^10 – 1/ 0.073
Future value= 4800 (2.0230062274104 – 1) / 0.073
Future value= 4800 (1.0230062274104) / 0.073

Expand the following, and simplify where possible: (a) bij bij . (b) bij yi yj , where bij =bji . (c) bij yi yj , where bij =−bji for I is not equal to j only.
This is the simplified form of the expression, taking into account the condition given.
(a) To expand the expression "bij bij", we need to remember that "bij" represents a constant or a variable.
Expanding "bij bij" means multiplying the expression by itself:
bij bij = bij * bij
This is the simplified form of the expression, and it cannot be simplified further unless we have more information about the values of "bij".
(b) To expand the expression "bij yi yj", we need to remember that "bij" represents a constant or a variable, and "yi" and "yj" represent variables or functions.
Expanding "bij yi yj" means multiplying all the terms together:
bij yi yj = bij * yi * yj
Again, this is the simplified form of the expression, and it cannot be simplified further unless we have more information about the values of "bij", "yi", and "yj".
(c) To expand the expression "bij yi yj" when bij = -bji for i is not equal to j only, we need to consider the condition that bij = -bji.
Since bij = -bji, we can substitute -bji for bij in the expression:
bij yi yj = (-bji) yi yj
Now, we can simplify further by distributing the negative sign:
(-bji) yi yj = -bij yi yj
This is the simplified form of the expression, taking into account the condition given.

f(x) = 2x - 3
g(x) = 3x - 1
Find (f. g)(x).
Step-by-step explanation:
The composition of two functions, f and g, is denoted as (f.g)(x) and is given by:
(f.g)(x) = f(g(x))
For the given functions f(x) = 2x - 3 and g(x) = 3x - 1, we have:
(f.g)(x) = f(g(x)) = f(3x - 1) = 2(3x - 1) - 3 = 6x - 5
So the composition of f and g is (f.g)(x) = 6x - 5.
Which of the binomials below is a factor of this expression?

answer- 5x-2yz
The binomials 5x-2yz are a factor of this expression
25x^2-4y^2z^2
This is further explained below.
What are binomials?Generally, A binomial is a kind of polynomial that is used in algebra and is defined as the sum of two terms, each of which is a monomial.
After monomials, this is the sort of sparse polynomial that is the easiest to understand.
The word "binomial" refers to an algebraic expression that consists of just two different terms. This is a polynomial with two terms.
25 x^2-4 y^2 z^2
Rewrite 25 x^2 as (5 x)^2.
(5 x)^2-4 y^2 z^2
Rewrite 4 y^2 z^2 as (2 y z)^2.
(5 x)^2-(2 y z)^2
Since both terms are perfect squares, factor using the difference of squares formula, a^2-b^2=(a+b)(a-b) where a=5 x and b=2 y z.
(5 x+2 y z)(5 x-(2 y z))
Simplify.

Slope intercept form is
y = mx+b where m is the slope and b is the y intercept
3x- 2y = 5
Solve for y
Subtract 3x from each side
3x -3x- 2y =-3x+ 5

Slope =3 and passes through (2,-5)
Y = 3x -11 is the equation where the slope is 3 and the coordinates pass through (2,-5)
what is slope ?What determines a line's steepness is its slope. Gradient overflow is a mathematical expression for the gradient (the change in y divided by the change in x). The slope is the proportion of the vertical increase (rise) over the distance between the two points to the width change (run) over the same distance. Slope-intercept form about an equation is used to express a straight line's equation, which is written as y = mx + b. A point on the line where the slope is m, b is b, and the y-intercept is placed is (0, b). An illustration would be the slope and y-intercept of the formula y = 3x - 7 (0, 7). At the location of the y-intercept, the line has a slope of m, b, and c. (0, b).

Which inequality statement describes the two numbers: - 22 and a number 47 units to the right of -22?
A)
-22 > 47
B)
-22 < 47
C)
-22 > 25
D)
-22 < 25
Answer:
D) -22 < 25
Step-by-step explanation:
If the number is 47 units to the right, then the number will be larger than -22, because negative values get larger the closer they are to zero.
47 units right from -22 is the same as: -22 + 47, which equals 25.
So, we can conclude that -22 < 25 is the inequality.
