You have a special type of function, so you have to express the domain and range of each interval. Every aspect of this graph is closed, so you will only use brackets when writing your answers. Hence, you get [30,5] for the first interval, since there is a horizontal distance of 30 and a vertical distance of 5. You repeat the same process for each interval.

$\text{Use}\ a^5+b^5=(a + b) (a^4 - a^3 b + a^2 b^2 - a b^3 + b^4).\\\\(x^5+y^5):(x+y)=\dfrac{x^5+y^5}{x+y}=\dfrac{(x+y)(x^4-x^3y+x^2y^2-xy^3+y^4)}{x+y}\\\\=\boxed{x^4-x^3y+x^2y^2-xy^3+y^4}$

Find the value of the expression 3m^2+2p^2-15 when m =3 and p = 10

mylen [45]

$3m {}^{2} + {2p}^{2} - 15$
m = 3
p = 10

$3 \times 3 {}^{2} + 2 \times {10}^{2} - 15 =$
$3 \times 9 + 2 \times 100 - 15 =$
$27 + 200 - 15 =$
$212$

Hence, the answer is 212.

16 The perimeter of the pentagon is equal to the perimeter of the square.

STatiana [176]

7x+2

Step-by-step explanation:

add all the sides of the pentagon and make it equal to the perimeter of the square which is 4y

sides of the pentagon are

5x+3

2x+3

7x+4

9x-10

5x+8

28x+8=4y

7x+2 = y

7x+2 = answer

another way :

in a standardized test you may want to use real numbers

make x equal a prime number like 3

so then the sides are

then divide by 4

then divide by 3

which is 7 remainder of 2

which is

7x+2
