Simplify the difference. (–7x – 5x^4 + 5) – (–7x^4 – 5 – 9x)

Answer: $2x^4+2x+10$

Step-by-step explanation:

You need to remember the mulplication of signs:

$(+)(+)=+\\(-)(-)=+\\(-)(+)=-$

Knowing this, you can distributive the negative sign. Then you get:

$(-7x- 5x^4 + 5) - (-7x^4 - 5 - 9x)=-7x- 5x^4 + 5 +7x^4 + 5 + 9x$

Now you need to add the like terms. Then:

$=2x+2x^4+10$

Finally, you can order the polynomial obtained in descending order. Therefore, the answer is:

$=2x^4+2x+10$

Perimeter of given figure is equal to :

Perimeter of square - side length + quarter Circumference of the circle

that is :

$\qquad \sf \dashrightarrow \:(10 \times 4) - (5 + 5) + \dfrac{2 \pi r}{4}$

$\qquad \sf \dashrightarrow \:40- 10 + \dfrac{3.14 \times 5}{2}$

$\qquad \sf \dashrightarrow \:30+ \dfrac{15.7}{2}$

$\qquad \sf \dashrightarrow \:30 + 7.85$

$\qquad \sf \dashrightarrow \:37.85 \: \: units$

So, the required perimeter is 37.85 units
