Answer:

202 cm^2

Step-by-step explanation:

SA = 2LW + 2LH + 2WH

SA = 2(4 cm)(5 cm) + 2(4 cm)(9 cm) + 2(5 cm)(9 cm)

SA = 40 cm^2 + 72 cm^2 + 90 cm^2

SA = 202 cm^2

Answer:

The density of cube is 6.17959 $\frac{g}{cm^{3} }$

Step-by-step explanation:

The density is given by ration of a mass of body and volume occupied by a body.

$\rho = \frac{m}{V}$

Where,

$\rho$ is density.

m is mass of a body

V is the volume of a body

Given that one side of the cube is 0.53cm

Hence, the volume of a body is V= $0.53^{3}$ =0.148877 $cm^{3}$

Now, the Density of the cube will be

$\rho = \frac{m}{V}$

$\rho = \frac{0.92}{0.148877}$

$\rho =6.17959$

Thus, The density of cube is 6.17959 $\frac{g}{cm^{3} }$

The low temperature in Anchorage, Alaska, one day was -9 degrees F. On the same day, the low temperature in Flagstaff, Arizona,

26>-9

This states that 26 is greater than -9. Look at the > sign like it's an alligator's mouth - the alligator wants to eat the bigger side, and 26 is clearly bigger than -9, so the alligator wants to eat 26!

Combine like terms.<br> - 2x - 14 = -3.- 1

UNO [17]

Answer:

combine -3-1

$- 2x - 14 = - 4$

if you want to solve for x then you would move the -14 to the left buy adding 14 to both sides.

$- 2x - 14 = - 4 \\ \: \: \: \: \: \: \: \: \: \: \: + 14 \: \: + 14$

your equation there will be

$- 2x = 10$

then you will divide -2 on both sides

$\frac{ - 2x}{ - 2} = \frac{10}{ - 2}$

finally x will equal

$x = - 5$
