Answer:

Option A

Step-by-step explanation:

2x^{2}-12x-50=0\\ \\2x^{2}-12x = 50\\

Divide through by 2

x^{2} - 6x = 25

But, x^{2} - 6x = (x-3)^{2} - 9\\ \\So, x^{2} - 6x = 25

Now becomes,

(x-3)^{2} -9=25\\\\(x-3)^{2}=25+9=34\\\\(x-3)^{2}=34

Because none of those are the right answer. you are given units in feet in the diagram. but are told 6 inches are lost in 4 hours. so you multiply length width and height keeping the feet then subtract .5 ft. the equation should look like V=(12×7×8)-.5

Find the length of line segmentAB which joins the following points.A(10, 14) and B(2,6)​
Helen [10]

Answer:

The equation of the line AB is  y - x -4 = 0

Step-by-step explanation:

The points are A (10,14) and B(2,6)

Now, slope of the line AB :  m = \frac{y_2 - y_1}{x_2 - x_1}

or, m = \frac{14 -6 }{10 - 2} = \frac{8}{8}  = 1

So, slope of the equation AB = 1

Now, by SLOPE INTERCEPT FORM:

The equation of line is given as :    y - y0 = m (x-x0)

So,the equation of line AB is  y - 6 = 1(x-2)

or, y - 6 -x + 2 = 0

or, y - x -4 = 0

Hence, the equation of the line AB is  y - x -4 = 0

HELPPPPPP!! ASAPPP!!! PLEASE!! WILL GIVE EXTRA POINTS!<br><br>4.8<br>4<br>8<br>7.2
vivado [14]

Answer:

x = 4

Step-by-step explanation:

180° - 114° = 66°

15x - 6 = 66

15(4) - 6 = 66

60 - 6 = 54      

Statement is wrong because we can see another angle. so...

Final answers: x = 4   while 54 + 114° = 168°  then 180° - 168° = 12°

The sum of two numbers is 45 and there difference is 5 what are the two numbers?
Kamila [148]
Let the two numbers be x and y.
The sum is 45, therefore
x + y = 45                    (1)

The difference is 5, therefore
x - y = 5                      (2)

Add equations (1) and (2).
x + y + (x - y) = 45 + 5
2x = 50
x = 25

From (1), obtain
25 + y = 45
y = 45 - 25 = 20


Answer:  20 and 25
