Answer:

x = −7

Step-by-step explanation:

2x + 3 = x − 4

Subtract 3 from both sides of the equation

2x = x −7

Subtract x from both sides of the equation

x = −7

Answer:

X=7

Step-by-step explanation:

Step 1

Having all the

terms on one side of =

Subtract

2 x

from both sides

2 x − 2 x + 3 = 3 x − 2 x − 4

0 + 3 = x − 4

Swap round

x − 4 = 3

Step 2

Have just

on the left of =

Add

to both sides

x − 4 + 4 = 3 + 4

x = 7

The answer is 8 and heres why:

$64^{\frac{3}{6}} \\\frac{3}{6}=\frac{1}{2} \\ \\64^{\frac{1}{2}} \\ \\\mathrm{Factor\:the\:number:\:}\:64=8^2 \\\left(8^2\right)^{\frac{1}{2}} \\ \\\mathrm{Apply\:exponent\:rule}:\quad \left(a^b\right)^c=a^{bc} \\\left(8^2\right)^{\frac{1}{2}}=8^{2\cdot \frac{1}{2}}=8$

And that is how you solve this promblem :-)

You are planning on retiling your bathroom floor and buy 96 square feet of tile. If the length of the bathroom is

Rudik [331]

Answer:

8 feet

Step-by-step explanation:

Given that 96 sq. feet of tile is bought to retile the bathroom.

It means area of bathroom is 9 $3/2 x^2 = 96\\=> 3 x^2 = 96*2=192\\=> x^2 = 192/3 = 64\\=>\sqrt{x^2} = \sqrt{64} \\=> x = 8$ 6 sq. feet

Width of bathroom be x

Given that the length of the bathroom is one and a half times the width

Length of bathroom in term sod width = 1 1/2* x = 3/2 x

we know area of rectangle is given by length * width

therefore area of bathroom =( x* 3/2 x) = 3/2 x^2

Also area of bathroom is 86 sq. feet, therefore

$3/2 x^2 = 96\\=> 3 x^2 = 96*2=192\\=> x^2 = 192/3 = 64\\=>\sqrt{x^2} = \sqrt{64} \\=> x = 8$

Thus, width of bathroom is 8 feet.
