Answer:

The surface area 76.32 in^2

Step-by-step explanation:

To find the surface area of a square pyramid we have to find the area of the base and the area of the sides and add them together.

Area of the base:

Since the base is a square, all we have to do is multiply 3.6 by 3.6.

3.6 * 3.6 = 12.96

The area of the base is 12.96 in^2

Area of the sides:

Since the sides are triangles, to find the area we have to multiply the length by the height and divide by 2.

3.6 * 8.8 = 31.68

31.68/2 = 15.84

The area of one of the sides is 15.84

Surface Area:

To find the surface area we have to add the area of the base and the area of the 4 sides together.

12.96 + 4(15.84)

12.96 + 63.36 = 76.32

The surface area is 76.32 in^2

What is x and the measurements?
nikitadnepr [17]

Answer:

see explanation

Step-by-step explanation:

The perimeter is the sum of the measures of the 3 sides.

Sum the sides and equate to 75, that is

2x - 9 + 3x + 4 + 2x + 3 = 75, that is

7x - 2 = 75 ( add 2 to both sides )

7x = 77 ( divide both sides by 7 )

x = 11

Thus

AB = 2x - 9 = 2(11) - 9 = 22 - 9 = 13 m

BC = 3x + 4 = 3(11) + 4 = 33 + 4 = 37 m

AC = 2x + 3 = 2(11) + 3 = 22 + 3 = 25 m

Solve for x: ( sqrt 7) ^ 6x = 49 ^ (x-6)
LiRa [457]
(\sqrt{7})^{6x}=49^{x-6} \\
(7^\frac{1}{2})^{6x}=(7^2)^{x-6} \\
7^{\frac{1}{2} \times 6x}=7^{2(x-6)} \\
7^{3x}=7^{2x-12} \\
3x=2x-12 \\
3x-2x=-12 \\
x=-12
