Answer:

136 m²: 188 m²

Step-by-step explanation:

I think your question missed key information, allow me to add in and hope it will fit the orginal one. Please have a look at the attached photo

My answer:

Given the information:

The height: 4m
The lenght: 13m
The width 4m

The lateral area:

As we know, the lateral area can be calculated by the following formula:

= the perimeter of the base* the height

= (13 + 4 + 13 + 4)*4

= 136 m²

The surface area:

As we know, the lateral area can be calculated by the following formula:

= The lateral area + thhe base area + the top area

= 136 + 13*4 + 13*4

= 136 + 52 + 52

= 240 m2

Which of the following expression is equal to x^2+25?

nignag [31]

A: (x + 5i)^2
= (x + 5i)(x + 5i)
= (x)(x) + (x)(5i) + (5i)(x) + (5i)(5i)
= x^2 + 5ix + 5ix + 25i^2
= 25i^2 + 10ix + x^2

B: (x - 5i)^2
= (x + - 5i)(x + - 5i)
= (x)(x) + (x)(- 5i) + (- 5i)(x) + (- 5i)(- 5i)
= x^2 - 5ix - 5ix + 25i^2
= 25i^2 - 10ix + x^2

C: (x - 5i)(x + 5i)
= (x + - 5i)(x + 5i)
= (x)(x) + (x)(5i) + (- 5i)(x) + (- 5i)(5i)
= x^2 + 5ix - 5ix - 25i^2
= 25i^2 + x^2

D: (x + 10i)(x - 15i)
= (x + 10i)(x + - 15i)
= (x)(x) + (x)(- 15i) + (10i)(x) + (10i)(- 15i)
= x^2 - 15ix + 10ix - 150i^2
= - 150i^2 + 5ix + x^2

Hope that helps!!!
