The figure shown in the right is made up of a square and a circle. Find the perimeter of the shaded region.
Tasya [4]

Answer:

B. 12 + 2pi cm

Step-by-step explanation:

The shaded region is made up of 3 square sides and one half circle. The three square sides are each 4, which means that those altogether equal 12.

The circle's circumference can be found by using the equation c = (d)pi

The diameter is 4, so the whole circumference is 4pi. However, you only need half of a circle, which is represented by 2pi.

Add them all together, and you get 12 + 2pi cm.

The sum of two polynomials is â€"yz2 â€" 3z2 â€" 4y 4. If one of the polynomials is y â€" 4yz2 â€" 3, what is the other polynomi
gtnhenbr [62]

The sum of polynomials involves adding the polynomials

The other polynomial is y^3 -y^2+ 4y - 1

The sum of the polynomials is given as:

Sum = y^3 + 3y^2 + 4y - 4

One of the polynomials is given as:

P = 4y^2 - 3

Represent the other polynomial with Q.

So, we have:

P +Q =Sum

Substitute the expressions for P and Sum

4y^2 - 3 +Q =y^3 + 3y^2 + 4y - 4

Make Q the subject

Q =y^3 + 3y^2 -4y^2+ 4y - 4 +3

Evaluate like terms

Q =y^3 -y^2+ 4y - 1

Hence, the other polynomial is y^3 -y^2+ 4y - 1
