Please help!! i also need to show work. <br><br><br> write in vertex form y = -3x^2 - 18x + 12
LuckyWell [14K]

Answer:

3(-x^2-6x+4)

Step-by-step explanation:

-3x^2 - 18x + 12

-3x^2 - (2 x 3^2) x + 2^2 x 3

3 (-3x^2 over 3 - 2x3^2 times x over 3 + 262 x 3 over 3)

3(-(x^2) - (2 x 3^2-1 times x) +2^2

3(-x^2 - (2 times 3x) +4)

3(-x^2-(6x) + 4)

3(-x^2 - 6x + 4)

A circular garden with a radius of 8 feet is surrounded by a circular path with a width of 3 feet.
Vladimir [108]

Answer:

178.98 ft2

Step-by-step explanation:

we know that

The area of the circular path alone is equal to subtract the area of the circular garden from the area of the complete circle (circular garden plus circular path)

so

A=\pi (r_2^2-r_1^2)

where

r_1=8\ ft ---> radius of circular garden

r_2=8+3=11\ ft ----> radius of the circular garden plus radius circular path

substitute

A=3.14 (11^2-8^2)=178.98\ ft^2

Can somebody help find the surface area if this
GrogVix [38]

The total surface area of the object shown in the diagram is 164 inches.

<h3>What is the total surface area?</h3>

The total surface area of a 3-dimensional object is the sum of the areas of the faces or surfaces of a 3-dimensional object. The object shown is the net of a cuboid.

Total surface area of a cuboid = 2 (lw + wh + lh)

where:

• l = length

• w = width

• h = height

2 { (10 x 3) + (10 x 4) + (4 x 3)}

2 (30 + 40 + 12)

2 x 82 = 164 inches
