Find the missing side

The answer you are looking for is 6.5.

To find this answer, you use the equation a² + b² = c², where c is the hypotenuse (the side with x in this case).

Next, fill in a and b with the two values given. Doing so will make the equation say 6² + 2.5² = c².

Now you solve for c.

6² = 36 and 2.5² = 6.25. (36 + 6.25 = c²)

36 + 6.25 = 42.25. (42.25 = c²)

√42.25 = 6.5. (6.5 = c)

Thus meaning 6.5 is the answer. I hope this helps!

Step-by-step explanation:

Use the Pythagorean theorem.

It's easy if you use a calculator.

Thanks.

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
