Hello!

You can use the Pythagorean Theorem to solve this

Separate the rectangle into two triangles

a^{2} + b^{2} = c^{2}

c is the diagonal
a and b are the side lengths

Put in the values you know

5^{2} + 4^{2} = c^{2}

Square the numbers

25 + 16 =  c^{2}

Add

41 =  c^{2}

Take the square root of both sides

6.4 = c

The answer is B) 6.4 units

Hope this helps!

A sector of a circle of radius "r" cm has an area of "A"cm². Express the perimeter of the sector in terms of "r" and "A"
Andrews [41]

Answer:

2A/r + 2r

Step-by-step explanation:

A sector is made of an arc and two radii. As such, the perimeter of the sector is the sum of the length of an arc and the two radii. Given that the radius is r and the area is A, the area of a sector A

= Ф°/360° * πr²

The length L of an arc of the sector

= Ф°/360° * 2πr

Hence,

A/L = r/2

L = 2A/r

The perimeter of the sector

= L + 2r

= 2A/r + 2r

Use the perfect square trinomial identity to write this expression in factored form:
Studentka2010 [4]

Answer:

(x + 5)²

Step-by-step explanation:

To get this we must find a binomial that multiplies by itself to get x² + 10x + 25.

(x + 5)(x + 5)

= x² + 5x + 5x + 25

= x² + 10x + 25
