Find the Surface Area of the prism please

Mathematics
1 answer:
Sergeeva-Olga [200]2 years ago
8 0

Answer:

<h2>1544 m³</h2>

Step-by-step explanation:

surface area = 2 × base + lateral area

 base = (10×20)÷2 = 100

 Lateral area = perimeter × height

                      = (20+14+14)×28

                      =1 344

Final answer :

surface area = 2 × base + lateral area

                     =  2 × 100 + 1344

                     =  200 + 1344

                     =  1544

A line with a slope of 2 passes through (3,9). Which choice is an equation of this line?
Veronika [31]

Answer:

The answer to your question is number 3.

Step-by-step explanation:

Data

slope = m = 2

Point = (3, 9)

Process

1.- Write the equation of the line in the form point-slope

               y - y1 = m(x - x1)

2.- Identify the values of x1 and y1

        x1 = 3   y1 = 9

3.- Substitution

               y - 9 = 2(x - 3)

4.- Simplify

              y - 9 = 2x - 6

              y = 2x - 6 + 9

5.- Result

              y = 2x + 3       slope y-intercept form
