In trapezoid RTUW, V is the midpoint of segment UW, and S is the midpoint of segment RT. Find UT.

andrezito [222]

The line VS is middle line of that trapezoid, so you know that it is

VS= (WR+UT)/2

so we will get that it is:

<span>40= (x^2+2 +2x^2+3)/2
x = 5

Therefore,

x^2 + 2
5^2 + 2
25 +2
27 <----- OPTION 2

Hope this answers the question.</span>

Solve for x <br> Need help asap

vlabodo [156]

Answer:

$x=55$

Step-by-step explanation:

Corresponding angles of two parallel lines are always equal. The angle on "top" of $2x+6$ corresponds with the angle marked as $x+9$ . Therefore, its measure must also be $x+9$ .

Since these two angles form one side of a line which has 180 degrees, we have the following equation:

$2x+6+x+9=180$

Combine like terms:

$3x+15=180$

Subtract 15 from both sides:

$3x=165$

Divide both sides by 3:

$x=\frac{165}{3}=\boxed{55}$

What is the linear function equation that best fits the data set?

slavikrds [6]

Answer:

Option 3

Step-by-step explanation:

Given data set is,

{(1.5, 1), (2.5, 3), (3, 3), (3, 5), (3.5, 5), (4.5, 7), (5, 7), (5, 9), (5.5, 9), (6.5, 11), (7.5, 13)}

By using linear regression calculator,

Equation of the linear function will be,

y = 2x - 2

Therefore, Option 3 will be the correct option.

Carly solved a quadratic equation by completing the square, but her work has errors. Identify the first error in Carly's work.

Savatey [412]

Answer:

Her first error was adding the wrong number to both sides. Instead of 4², it should be 2²

Step-by-step explanation:

When completing the square, the number that needs to be added to both sides is (b/2)²

In this problem, b is 4. So, Carly should have added 2² to both sides, but she added 4² instead.

So, her first error was adding 4² to both sides instead of 2²
