Answer:

First side is: 12cm

Second side is: 36cm

Third side is: 16cm

Step-by-step explanation:

Let x represent the shorter side

Then 3x represents the second side, and

x + 4 represents the third side.

Perimeter of three sides:

P = x + 3x + (x + 4)

Perimeter is 64, so

64 = x + 3x + (x + 4)

64 = 5x + 4

60 = 5x

12 = x

First side is x: 12cm

Second side is 3x: 3(12) = 36cm

Third side is x + 4: 12 + 4 = 16cm

Ipatiy [6.2K]

Answer:

4 hours

Step-by-step explanation:

I found the average

(3+5)/2

8/2 = 4

This is probably wrong because logically it wouldn't make sense for them to take longer than 3 hours if two people are cleaning but i dont know

Which answer is a factored form of the expression below?
katrin2010 [14]

Answer:

c: is the answer 2 (3 x + 4) (x + 2)

Step-by-step explanation:

Factor the following:

6 x^2 + 20 x + 16

Factor 2 out of 6 x^2 + 20 x + 16:

2 (3 x^2 + 10 x + 8)

Factor the quadratic 3 x^2 + 10 x + 8. The coefficient of x^2 is 3 and the constant term is 8. The product of 3 and 8 is 24. The factors of 24 which sum to 10 are 4 and 6. So 3 x^2 + 10 x + 8 = 3 x^2 + 6 x + 4 x + 8 = 2 (3 x + 4) + x (3 x + 4):

2 2 (3 x + 4) + x (3 x + 4)

Factor 3 x + 4 from 2 (3 x + 4) + x (3 x + 4):

Answer:  2 (3 x + 4) (x + 2)

A right rectangular prism is sliced parallel to the base. What is the area of the resulting two-dimensional cross-section?
stepan [7]

Answer:

The area of the resulting two-dimensional cross-section is 12 cm².

Step-by-step explanation:

The area of the cross-section of the right rectangular prism, parallel to the base, is given by the area of a rectangle:

A_{cs} = A_{r} = a*b

Where:

A_{cs}: is the area of the cross-section

A_{r}: is the area of a rectangle

a: is the length of one side of the rectangle = 4 cm

b: is the length of the other side of the rectangle = 3 cm

Hence, the area of the cross-section is:

A_{cs} = a*b = 4 cm*3 cm = 12 cm^{2}      

Therefore, the area of the resulting two-dimensional cross-section is 12 cm².      

I hope it helps you!
