Answer:

94 square ft

Explanation:

as given in the question, the formula for surface area is 2lw + 2lh + 2wh, which means (2 × length × width) + (2 × length × height) + (2 × width × height). since these values are given, we just have to place them into the equation as such:

(2 × 5 × 4) + (2 × 5 × 3) + (2 × 4 × 3)

= 40 + 30 + 24

= <u>94</u>

so, the surface area is 94 square ft.

An octagon has seven sides which have a length of k feet. The eighth side has a length of 3.9 feet, as shown below. The perimete

diamong [38]

Answer:

K is 3.4 feet

Step-by-step explanation:

To find the perimeter of the octagon, we add up the lengths of all the sides

For this particular octagon;

7 * k + 3.9 = 27.7

7k + 3.9 = 27.7

7k = 27.7-3.9

7k = 23.8

k = 23.8/7

k = 3.4 feet

Amelia is 3 years younger than Etta. The product of their ages is 40. How old is Amelia?

Paul [167]

Answer:

Amelia is <u>5 years</u> old

Let x be Amelia and y by Etta.

[] Amelia is 3 years younger than Etta.

x = y - 3

[] The product of their ages is 40.

x * y = 40

We can use a system of equations to solve

[] The system

a = e - 3

a * e = 40

[] Graphing

-> See attached

[] The answer is 5

Have a nice day!

I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly.
