To simplify a fraction by division you must have common factors between the denominator and the neominator to divide (or cancel) them

Which equation has no solution?

sladkih [1.3K]

Answer:

-2(6-3x)=-12+6x

Step-by-step explanation:

If you do the distributive property first and look at the other side of the = sign they are the same, which means that the answer would be x=x, which isn't a solution.

Point B lies between points A and C, and all three points lie on point AC, which of the following is not true? A. Point B lies o

loris [4]

Answer:

C. Point A lies on ray BC

Step-by-step explanation:

Points A and C can be connected by a segment which would be a measure of the distance between the points. Locating point B between AC, makes the three points lying on segment AC.

A ray extends from a point to infinity, a line extend to infinity on both sides, while a segment is known to have two endpoints. Therefore, points AC are the end points of the segment AC, and point B between this segment confirms that point B lies on the segment AC. Therefore, Point A lies on ray BC is not correct.

Jobisdone [24]

Answer:

$\frac{a(450-8a^2)}{4}$

is the volume in terms of side a

Step-by-step explanation:

Given that you I built a storage shed in the shape of a rectangular box on a square base. The material that I used for the base cost $4 per square foot, the material for the roof cost $2 per square foot, and the material for the sides cost $2.50 per square foot; and I spent $450 altogether on material for the shed.

Let a be the side of square and h be the height

Total cost of materials = cost for floor + cost for roof + cost for sides

= area of floor (4) + lateral area (2.50)+roof area (2)

$=4a^2+4ah+4a^2\\=8a^2+4ah = 450$ $h = \frac{450-8a^2}{4a}$

Now coming to volume

Volume = V = lbh = $a^2 h\\= a^2*\frac{450-8a^2}{4a} \\=\frac{a(450-8a^2)}{4}$

In which step did Viet make an error? 2 ( x − 3 ) 2 + 4 = 102 2 ( x − 3 ) 2 = 106 Step 1 ( x − 3 ) 2 = 53 Step 2 x − 3 = ± 53 St

vitfil [10]

Answer:

Step 2

Step-by-step explanation:

Given

Step 1: $2(x - 3)^2 + 4 = 102$

Step 2: $2(x - 3)^2 = 106$

Step 3: $x - 3 = \±\sqrt{53$

Step 4: $x = \±\sqrt{53} + 3$

Required

Where did Viet made an error?

The step 1 indicates the original question.

$2(x - 3)^2 + 4 = 102$

To get to step 2, we have to subtract 4 from both sides of the equation.

$2(x - 3)^2 + 4 -4= 102 - 4$

$2(x - 3)^2 = 98$

However, the above expression is different from Viet's evaluation.

<em>Hence, we can conclude that Viet made an error in step 2</em>

Wich set of ordered pairs does not represent a function.<br> Please help.

pantera1 [17]

Answer:

Step-by-step explanation:

A function has to have only one y-value for every x-value. This means that D is not a function because it contains (6,2) and (6, 4), which means that there are 2 different y-values for the x-value of 6.
