To solve the leg of a right triangles given the two other side, use the pythagorean theorem. which state that
C^2 = a^2 + b^2
where C is the hypotenuse of the right triangle
a and b are the legs of the right triangle
since the unknown is the other leg
b^2 = C^2 - a^2
b^2 = 18^2 - 14^2
b^2 = 128
b = 11.3 cm

What is another way to write the equation 7/8x3/4=-6

prohojiy [21]

Another way to write the equation is 7x + 54 = 0

<h3>How to rewrite the equation</h3>

Given the equation;

$\frac{7}{8}x + \frac{3}{4} = -6$

Find the LCM on the left side, which is 8

$\frac{7x + 6}{8} = -6$

Cross multiply

$7x + 6 = -6$ × $8$

$7x + 6 = -48$

Collect like terms

$7x = -48 - 6$

$7x = -54$

Take all to one side

$7x + 54 = 0$

Thus, another way to write the equation is 7x + 54 = 0
