Two of the sides of a right triangle are 8 and 6 units long. How long is the third side? Find all possible answers.
Lana71 [14]

Answer:

10 units.

2√7 units.

- (or 5.29 units to the nearest hundredth)

Step-by-step explanation:

If the 2 sides are legs of the triangle ( that is they are at 90 degrees to each other) the third side, by Pythagoras  theorem:

=  √(6^2 + 8^2)

=  √100

= 10 units.

The other possibility is that 8 is the length of the hypotenuse, in which case

The third side

=  √(8^2 - 6^2)

=  √28

= 2√7 units.

8x-3(2x-4)≤ 3(x-6)
OlgaM077 [116]

The solution to the inequality expression is x ≥ 30

<h3>How to solve the inequality expression?</h3>

The inequality expression is given as:

8x - 3(2x - 4) ≤ 3(x - 6)

Open the brackets in the above inequality expression

8x - 6x + 12 ≤ 3x - 18

Collect the like terms in the above inequality expression

8x - 6x - 3x  ≤ -12 - 18

Evaluate the like terms in the above inequality expression

-x  ≤ -30

Divide both sides of the above inequality expression by -1

x ≥ 30

Hence, the solution to the inequality expression is x ≥ 30

Work out m and c for the line: ? y = x + 6​
lapo4ka [179]
Well your c value is already there (6) as the standard equation for a line is
y = mx + c

To find the gradient (M) plot two points on the line.

Then label each co ordinate X1 and X2 and then Y1 and Y2

Then subtract your y1 from y2 and then x1 from x2.

For example :if your coordinates were (1,2) (3,4) you would do
4-2 and 3-1

These answers become your “changes” now do change in y / change in x

In terms of the Example you would do 2/2 which would be 1 and the M value would be 1

Hope that isn’t too confusing
