Answer:

<h2>Step 2</h2>

Step-by-step explanation:

Given the quadratic equation  6x² + 24x + 7 = 0, the following steps must be followed when finding the roots using the completing the square method.

Step 1: Subtract 7 from both sides

6x² + 24x + 7 - 7= 0 -7

6x² + 24x = -7

Step 2: divide through by the coefficient of x²

6x²/6 + 24x/6 = -7/6

x² + 4x = -7/6

Step 3: Add half of the coefficient of x (i.e 4/2 = 2) to both sides of the equation to complete the square of the equation x² + 4x.

x² + 4x + 2= -7/6 + 2

(x+2)² = -7/6 + 2

(x+2)²  = 5/6

Step 4: taking the square root of both sides

√(x+2)²  = √5/6

x+2 = ±√5/6

x = -2±√5/6

x = -2+√5/6 and -2-√5/6

Based on the conclusion above, it can be seen that Yvonne made the first error in step 2. Yvonne suppose to divide through by the coefficient of x² (i.e 6)

Which system of linear inequalities is represented by the graph?
masha68 [24]
For the red line, we have:
 
gradient (m) = 1/3
y-intercept = 3

Equation of straight line is given by y=mx+c, where m is the gradient and c is where the line intercept the y-axis

So we have, y= \frac{1}{3}x+3

The shaded part is above the line, hence the first inequality is
y \geq \frac{1}{3}x+3

The black line, we have
gradient, (m) = 3
y-intercept = -2

y=mx+c
y=3x-2, rearranging gives
3x-y=2

The shaded region is to the right of the line, hence the inequality is
3x-y\ \textgreater \ 2

Note: The first option should be the correct answer but the inequality sign for <span>y > 1/3x + 3 should be </span>\geq

Largest Possible GCF (Greatest Common Factor)
Ipatiy [6.2K]

Answer:

<h2>96 and 48</h2>

Step-by-step explanation:

To solve this problem we have to find the largest possible greatest common factor, which is 48.

Now, numbers 96 and 48 have as Greatest Common Factor 48, that's the largest number possible that is common to both numbers because

48/48 = 1

96/48 = 2

Therefore, the answer is 96 and 48, because they don't have repetitive digits.

4/3+căn5 - 8/1+căn5 +15/căn5
padilas [110]

Answer:

A= \frac{4}{3 +  \sqrt{5} }  -  \frac{8}{1 +  \sqrt{5} }  +  \frac{15}{ \sqrt{5} }

=  \frac{4(3 -  \sqrt{5)} }{4}  -  \frac{8(1 -  \sqrt{5} }{ - 4}  +  \frac{15 \sqrt{5} }{5}  = 3 -  \sqrt{5 + 2 - 2 \sqrt{5 + 3 \sqrt{5 = 5} } }

If the area of a trapezoid is 28 m with a height of 14 m in with one of the base being 1 m to find the length of the second face
In-s [12.5K]
The area of a trapezoid is basically the average width times the altitude, or as a formula:
Area = h ·

b 1 + b 2
2


where
b1, b2 are the lengths of each base
h is the altitude (height)
Recall that the bases are the two parallel sides of the trapezoid. The altitude (or height) of a trapezoid is the perpendicular distance between the two bases.

In the applet above, click on "freeze dimensions". As you drag any vertex, you will see that the trapezoid redraws itself keeping the height and bases constant. Notice how the area does not change in the displayed formula. The area depends only on the height and base lengths, so as you can see, there are many trapezoids with a given set of dimensions which all have the same area.
