Answer:

\boxed{1}

Step-by-step explanation:

x^{2m+n} * x^{n-m} / x^{m+2n}

When bases are same for exponents in division, subtract exponents.

x^{2m+n} * x^{n-m-(m+2n)}

x^{2m+n} * x^{n-m-m-2n}

x^{2m+n} * x^{-n-2m}

When bases are same for exponents in multiplication, add exponents.

x^{2m+n+-n-2m}

x^{2m+0-2m}

x^0

Any base with power or exponent of 0 is 1.

x^{0}=1

A rectangular countertop has a perimeter of 24 feet. its area is 27 square feet. what are the dimensions of the counter?
Kaylis [27]
You can solve this by setting up 2 equations and solving quadratically.

perimeter of a rectangle is found by the formula 2*base + 2*height = perimeter.
area is found by base*height=area.
2b+2h = 24 and b*h=27 solving one equation for base or height and substituting in the other equation will give us an equation we can use for this particular problem. solving b*h=27 for b will give us b= 27/h. substituting this into the perimeter equation we get 2(27/h) + 2h = 24. If we use algebra to manipulate the equation we get 24-2h= 2(27/h) so 24-2h = 54/h multiplying both sides by h give (24-2h)h = 54 moving the 24h-2h^2 to the other side gives 0 = 2h^2-24h+54 solving the quadratic for h gives (2h+6)(h+9)=0 so solving for h we get h=6/2 = 3 or    h=9 is we use h =9 and plug it into the original equation for 2b+2h=24 then we get 2b+2(9)= 24 so then 2b = 24-18 so b = 6/2 =3. so we get 2(3)+2(9)=24 so 6+18=24 for perimeter and for b*h=27 we get 3*9=27 so the dimensions are 3x9 3 is the shorter side and 9 is the longer side = 3x9

Find the value of x. Show all work.
Mashutka [201]

Answer:

x = -8°

Step-by-step explanation:

Angle 2

Since the triangle is isosceles, Angle 2 is the same as the missing angle

So angle 2 would be:

180 - 34 = 2(angle 2)

So 146 = 2(x + 81)

146 = 2x + 162

146 - 2x = 162

-2x = 16

x = -8

Check

146 = 2(-8+81)

146 = 2(73)

146 = 146

Correct!

If my answer is incorrect, pls correct me!

If you like my answer and explanation, mark me as brainliest!
