The perimeter of the trapezoid-shaped window frame is 23.59 feet. Write and solve an equation to find the unknown side length x

krok68 [10]

Answer:

$5.62 + 3.65 + 5.62 + x = 23.59$

$x = 8.7 ft$

Step-by-step explanation:

Perimeter of the trapezoid-shaped window = sum of all the sides of the window frame

Thus, the equation to find the unknown side length, x, would be:

✔️ $5.62 + 3.65 + 5.62 + x = 23.59$

Solve for x

$14.89 + x = 23.59$

Subtract 14.89 from each side

$14.89 + x - 14.89 = 23.59 - 14.89$

✔️ $x = 8.7 ft$

Find the center and radius of each.

Marysya12 [62]

x^2+y^2=49

Radius 7
Center (0,0)

x^2+y^2=324

Radius 18
Center (0,0)

x^2+(y+2)^2=121

Radius 11
Center (0, -2)

(x+10)^2+(y+9)^2=8

Radius 2√2≈2.82843
Center (-10, -9)

Which expression is equivalent to the following complex fraction? X+5/x+2-x+1/x^2+2x

ICE Princess25 [194]

Answer:

Final answer will be the choice which matches best with expression

$\frac{x^2+4x-1}{x\left(x+2\right)}$ or

$\frac{x^2+4x-1}{x^2+2x}$

Step-by-step explanation:

Given expression is:

$\frac{\left(x+5\right)}{\left(x+2\right)}-\frac{\left(x+1\right)}{\left(x^2+2x\right)}$

We begin by factoring denominators:

$=\frac{\left(x+5\right)}{\left(x+2\right)}-\frac{\left(x+1\right)}{x\left(x+2\right)}$

Multiply and divide first term by (x) to make denominators equal.

$=\frac{x\left(x+5\right)}{x\left(x+2\right)}-\frac{\left(x+1\right)}{x\left(x+2\right)}$

Since denominators are equal so we can combine numerators.

$=\frac{x\left(x+5\right)-\left(x+1\right)}{x\left(x+2\right)}$

Now simplify

$=\frac{x^2+5x-x-1}{x\left(x+2\right)}$

$=\frac{x^2+4x-1}{x\left(x+2\right)}$

$=\frac{x^2+4x-1}{x^2+2x}$

Hence final answer will be the choice which matches best with expression

$\frac{x^2+4x-1}{x\left(x+2\right)}$ or

$\frac{x^2+4x-1}{x^2+2x}$

in september 2007, the average price of gasoline was $2.81 a gallon. This price represented an increase of $2.31 less than twice

hodyreva [135]

Answer:

x = $2.56

Step-by-step explanation:

To solve this, you do the inverse of both operations, which is multiplication and subtraction. The first inverse would be addition, so 2.81 + 2.31 = 5.12. Then, the second inverse would be division, so 5.12 divided by 2 = 2.56. So therefore, x = $2.56 is the correct answer for the price in September 2006.
