The perimeter of a rectangle is 40 feet. The ratio of the width to the length is 2:3 find the length and the width

ziro4ka [17]

Width : Length

2 : 3

Perimeter = 2* width + 2*length

Ratio becomes:

Width : Length

4 : 6

Total units = 4 + 6 = 10

Perimeter = 40

Answer: Width is 8 ft and Length is 12 ft.

A father's age is 4 times as that of his son's age. in 5 years time, the father will be 3 times as old as his son. what are thei

Vadim26 [7]

Answer:

<h3>present age of son = 10 </h3><h3>present age of father = 40</h3>

Step-by-step explanation:

Let, present age of son be 'x'

present age of father be 'y'

y = 4x→ equation ( i )

After five years,

Son's age = x + 5

father's age = y + 5

According to Question,

$y + 5 = 3(x + 5)$

Put the value of y from equation ( i )

$4x + 5 = 3(x + 5)$

Distribute 3 through the parentheses

$4x + 5 = 3x + 15$

Move variable to L.H.S and change it's sign

Similarly, Move constant to R.H.S. and change its sign

$4x - 3x = 15 - 5$

Collect like terms

$x = 15 - 5$

Calculate the difference

$x = 10$

Now, put the value of X in equation ( i ) in order to find the present age of father

$y = 4x$

plug the value of X

$= 4 \times 10$

Calculate the product

$= 40$

Therefore,

Present age of son = 10

present age of father = 40

Hope this helps..

Best regards!!

Answer:

f(x) = 7

Step-by-step explanation:

since an even function is defined as a function with the following rule. f(-x) = f(x) for all x in the domain of f(x). It would be odd if f(-x) = -f(x) for all x in the domain of f(x). If f(-x) ≠ -f(x), than it is neither. these are all known as the parity of a function.

you can apply these rules to all of given functions like this. (-x-1) ≠ -(x-1) so it is neither. 8(-x) = -(8x) so it would be odd. 2(-x)-(-x) = -(2x-x) so it is odd as well. This would make f(x) = 7 the only option, as there are no x variables in the equation so 7 = 7.
