spin [16.1K]3 years ago
4 0

See below

Step-by-step explanation:

A =  {9}^{2}  = 81 \\  \\ A =  {12}^{2}  = 144 \\  \\ x =  \sqrt{81 + 144}  \\  \\  =  \sqrt{225}  \\ \\   = 15\\\\A =  {15}^{2}  = 225

Han has 10 cubes, each 5 inches on a side. Find the total volume of Han's cudes Express your answer as an expression using an ex
docker41 [41]

Answer:

2 * 5⁴

Step-by-step explanation:

Given :

Number of cubes = 10

Side length, a of each cube = 5

The volume of a cube = (side length)³

Hence, the volume of each of Han's cube = 5³

Therefore, the total volume will be :

Volume or cube * number of cubes

5³ * 10

10 = 2 * 5 = 2 * 5¹

5³ * 2 * 5¹

2 * 5^(3 +1)

2 * 5⁴

A line passes through the point (-5,-1) and has a slope of 4
vesna_86 [32]

Hello.

We have a point that the line passes through:

\mathrm{(-5,-1)}

We also have the line's slope:

\mathrm{4}

Right now, we do not have enough information to write the equation of the line in slope-intercept form. We need to know the slope and the y-intercept. We do know the slope, but we do not know the y-intercept...yet.

We do have enough information to write the line's equation in Point-Slope Form:

\mathrm{y-y1=m(x-x1)}

Plug in the values:

\mathrm{y-(-1)=4(x-(-5)}

\mathrm{y+1=4(x+5)}

Use the Distributive Property (a(b+c)=ab+ac) :

\mathrm{y+1=4x+20}

Move 1 to the right:

\mathrm{y=4x+20-1}

Subtract:

\mathrm{y=4x+19}

Now we have the equation in slope-intercept form.

Therefore, the answer is

\mathrm{y=4x+19}

I hope it helps.

Have a nice day.
