What is the area of the shaded region? (Approximate π to be 3.14)

kifflom [539]

Answer:

about 113.04 square inches

Step-by-step explanation:

No angles are indicated, so we must assume the sector is 1/4 of the circle. Then its area is 1/4 of that of a circle with radius 12 in:

Circle area = πr²

Sector area = (1/4)π(12 in)² = 36π in²

Sector area ≈ 36(3.14) in² = 113.04 in²

Solve the equation:<br>5 - 20 =<br>– 15<br>Enter answer below<br>Enter your response

Ipatiy [6.2K]

Answer:

Step-by-step explanation:

First add 20 to both sides to get x/3 = 5

Then multiply both sides by 3 to get 15.

You can check it by substituting it into the equation

15/3 - 20 = -15

5 - 20 = -15

-15 = -15

Which products result in a difference of squares or a perfect square trinomial? Check all that apply.

tiny-mole [99]

Answer:

Option B) (7x+4)(7x+4) is correct

The product result in a perfect square trinomial is

$(7x+4)(7x+4)=49x^2+56x+14$

Step-by-step explanation:

$(7x+4)(7x+4)=(7x+4)^2$ ( using $(a+b)(a+b)=(a+b)^2$ )

$=(7x)^2+2(7x)(4)+4^2$ ( using $(a+b)^2=a^2+2ab+b^2$ )

$=7^2x^2+56x+16$

$=49x^2+56x+14$

Therefore $(7x+4)(7x+4)=49x^2+56x+14$

which is a perfect square trinomial

A trinomial is a perfect square trinomial if it can be factored into a binomial multiplied to itself. In a perfect square trinomial, two terms will be perfect squares.

Option B) (7x+4)(7x+4) is correct

The product result in a perfect square trinomial is

$(7x+4)(7x+4)=49x^2+56x+14$
