Answer:

96 cm²

Step-by-step explanation:

Triangular face:

base = 8 cm

height = 6 cm

Area of triangle = $\dfrac{1}{2}*b*h$

$= \dfrac{1}{2}*8*6\\\\=4*6\\\\= 24 \ cm^{2}$

Area of 4 triangular faces = 4 * 24 = 96 cm²

Answer:

Step-by-step explanation:

y - 3 = 1/4(x - 4)

now use algebra to get the above point-slope formula in the slope-intercept formula

y - 3 = 1/4(x - 4)

y - 3 = 1/4x -1

y = 1/4x +2

now that you have the slope-intercept form graph it

Trey solved the equation 1/4(8x+16) = 4x, the answer he got was 8=x. Describe the error he made. Then solve the problem...PLZ HE

Dimas [21]

In this case, you can multiply both sides by 4 to get rid of the 1/4 real quick.
4[1/4(8x+16=4x]
8x+16=16x
8x=16
x=2

The graph below shows a system of equations:

rosijanka [135]

The system of equations:
2 y = - x - 1
2 y = x + 5
---------------------
- x - 1 = x + 5
- 2 x = 5 + 1
- 2 x = 6
x = - 6 : 2
x = - 3
2 y = - 3 + 5
2 y = 2
y = 1
The solution is ( - 3 , 1 ).
Answer: The x-coordinate of the solution to the system is: x = - 3.
