What is the reason for each step in the solution of the equation?<br><br> −6x+7x+14=3

sertanlavr [38]

-6x + 7x + 14 = 3
First, you add the variables x between each other so we can have one number with variable x:
x + 14 = 3
Then, subtract 14 from each side to get the variable x alone of a side, and its value on the other side:
x + 14 - 14 = 3 - 14
x = - 11

You can re-check your answer (very important):
-6x + 7x + 14 = -6(-11) + 7(-11) + 14 = 66 - 77 + 14 = -11 + 14 = 3
The answer has been approved.

Hope this Helps! :)

We know Logan's watch is still under warranty because,

1 week = 7 days.

6 weeks × 7 days = 42 days

But he has 90 days, so there is still more than 50 days that he can go return it and will get his money back.

Segment BD is an altitude of triangle ABC. Find the area of the triangle.

Sever21 [200]

Answer: The correct option is A, i.e., 7.5.

Explanation:

It is given that ABC is a triangle and BD is an altitude.

Since BD is an altitude, therefore the height of the triangle is BD and the base of the triangle is AC.

The distance formula to find the distance between two points is,

$D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

First, we find BD, where B(-1,4) and D(2,4).

$BD=\sqrt{(2+1)^2+(4-4)^2}=\sqrt{9} =3$

So, the height of the triangle is 3.

Now, we find the value of AC, where A(2,1) and C(2,6).

$AC=\sqrt{(6-1)^2+(2-2)^2}=\sqrt{25} =5$

So, the base of the triangle is 5.

The formula to find the area of a triangle is,

$A=\frac{1}{2}\times {\text{base}}\times {\text{height}}$

$A=\frac{1}{2}\times 5\times 3=\frac{15}{2}=7.5$

Therefore, the area of the triangle is 7.5 unit square and the correct option is A.
