Hello,

We have : (a + b)² = a² + 2ab + b²

4x² + 20x + 25 = (2x)² + 2 × 2x × 5 + 5² = (2x + 5)² → answer B

Here, we have a = 2x and b = 5 !

SCORPION-xisa [38]

Answer:

1. 9/25 units^2

2. s = 1/4 unit

3. = 8/27 units^3

4. s = 3/4 unit

Step-by-step explanation:

1. The area of a square is A=s^2

A = (3/5)^2

= (3/5) *(3/5)

= 9/25 units^2

2. The area of a square is A=s^2

1/16 = s^2

Take the square root of each side

sqrt(1/16) = sqrt(s^2)

1/4 = s

s = 1/4 unit

3. The volume of a cube is V = s^3

V = (2/3)^3

= (2/3) (2/3) (2/3)

= 8/27 units^3

4.The volume of a cube is V = s^3

27/64 = s^3

Take the cube root of each side

(27/64)^(1/3) = (s^3)^(1/3)

3/4 = s

s = 3/4 unit

Maya is finding the area of the shaded triangle below. A triangle has a base of 73 meters and a height of 10 meters. If she cons

zavuch27 [327]

The triangle is missing, so i have attached it.

Answer:

Correct answer is option D - 73m

Step-by-step explanation:

From the attached image of the triangle, we can see that the base has 22m and 73m.

However, the question says we want to find the area of the shaded triangle. Thus, we'll make use of the entire base.

To this effect, the base will be 73m as shown

A rancher has 600600 feet of fencing to put around a rectangular field and then subdivide the field into 33 identical smaller re

SIZIF [17.4K]

Answer:

x = 150 ft

y = y = 150 / 17 ft

Step-by-step explanation:

Area of the field is A = x*y

Let´s assume x is the larger side of the rectangle, and that we will get 33 identical smaller rectangular plots dividing x into 33 rectangles ( using 34 sides of length y ) then the quantity of fence is:

p = 2*x + 34*y ⇒ 600 = 2*x + 34*y y = ( 600 - 2*x)/34

A = x*y

A (x) = x* ( 600 - 2*x)/34

A (x) = ( 600*x - 2*x²)/34

Taking derivatives on both sides of the equation:

A´(x) = (1/34)* ( 600 - 4*x )

A´(x) = 0 (1/34)* ( 600 - 4*x ) = 0 600 - 4*x = 0

x = 600/4

x = 150 feet

And y = (1/34)( 600 - 2*150)

y = 300/34 y = 150 / 17 ft

y = 8.82 ft

How do we know that is a maximum area, we find the second derivative of A

A´´(x) = - 4/34 then A´´(x) < 0

We get a maximum of function A for the value x = 150
