Take the linear coefients easy

11,-12, 7
5,12,-7
so

\left[\begin{array}{ccc}11&-12&7\\5&12&-7\end{array}\right] or you could do also
\left[\begin{array}{ccc}11&-12\\5&12\end{array}\right]   \left[\begin{array}{ccc}7\\-7\end{array}\right]

A surface area of a cube is related to its volume V by A = 6. V(2/3). If the volume of a
Luda [366]

The surface area of the cube is 64 cm².

<h3 /><h3>What is volume?</h3>

Volume is the amount of space that is enclosed within a container.

To calculate the surface area of the cube, we use the relation below.

Formula:

  • A = 6V{2/3}............ Equation 1

Where:

  • A = Surface area of the cube
  • V = Volume of the cube.

From the question,

Given:

  • V = 35 cm³

Substitute this value into equation 1

  • A = 6(35){2/3}
  • A = 6(10.6999)
  • A = 64.2
  • A = 64 cm²

Hence, The surface area of the cube is 64 cm².

Ashley drove 5 hours and 45mins and drove 391 miles. How far did she drive in 1 hour
klasskru [66]
1 hour = 60 minutes
5 x 60 = 300
300 + 45 = 345

391 miles/345 min = 1.13 miles per min
1.13 x (60 min/1 mile) = 67.8 miles per hour

Ashley drove ~67.8 miles per hour

hope this helps

Number 5 should be no solution becuase the n's cancel out.

For 6:
Part A is -2 because slope represents the change in weigh/change in time (-2/1 or -2)
Part B is y=-2x+231 (-2 is the slope and 231 is the y-intercept)
For part C, based on the slope, we can find that her weight will go below 200 at week 16 when it is 199

Hope this helps!
