Answer:

SA = 76 cm²

Step-by-step explanation:

Surface Area (SA) of a cuboid: 2(lw) + 2(wh) + 2(hl)

SA = 2(lw) + 2(wh) + 2(hl)

l = 4 cm
w = 2 cm
h = 5 cm

Substitute the values above and multiply:

SA = 2(lw) + 2(wh) + 2(hl)

SA = 2(4)(2) + 2(2)(5) + 2(5)(4)

SA = 2(8) + 2(10) + 2(20)

SA = 16 + 20 + 40

SA = 76 cm²

Final answer: 76 cm²

Hope this helps!

What is the slope between (14,-8) and (7,-6)

djyliett [7]

Answer:

$- \frac{2}{7}$

Step-by-step explanation:

Slope formula:

$\boxed{ slope = \frac{y _{1} - y_2 }{x_1 - x_2} }$

where (x₁, y₁) is the first coordinate and (x₂, y₂) is the second coordinate

Slope

$= \frac{ - 8 - ( - 6)}{14 - 7}$

$= \frac{ - 8 + 6}{7}$

$= - \frac{2}{7}$
