What’s the surface area

STALIN [3.7K]

Answer: 38 in.^{2}

Step-by-step explanation:

1/ Find the area of the triangular sides. (1/2 x 2 x 6 = $6 in.^{2}$ for each triangular side)

2/ Find the area of each of the rectangular sides. In this case, the bottom (base) side is 2x6 = $12 in^{2}$ . The rectangular side on the left is 2x3 = $6 in.^{2}$ , and the rectangular side on the right is 4x2 = $8 in.^{2}$ .

3/ Add everything together. Rectangular Sides + Triangular Sides = Surface Area ---> $12 in.^{2} + 6 in.^{2} + 8 in.^{2} + 6 in.^{2} + 6 in.^{2} = 38 in.^{2}$

4/ You have your answer, now hope it helps ! :)

Solve for x in the first equation, then solve the system using substitution. Write your answer as (x, y).

OleMash [197]

2x - 6y = 14
2x = 6y + 14
x = 3y + 7.....so sub in 3y + 7 for x in the other equation

4x - y = 9
4(3y + 7) - y = 9
12y + 28 - y = 9
12y - y = 9 - 28
11y = - 19
y = -19/11

x = 3y + 7
x = 3(-19/11) + 7
x = -57/11 + 7
x = -57/11 + 77/11
x = 20/11

solution is : (20/11, -19/11) <==
