Answer:

a) x = 5

b) x = 4

Step-by-step explanation:

a) 4x - 3 = 2x + 7 collect like terms

4x - 2x = 7 + 3

2x = 10 divide both sides by the coefficient of x

x = 5

b) 2x + 6 = 7x - 14 collect like terms

2x - 7x = -14 - 6

-5x = -20 divide both sidess by the coefficient of x

x = 4

A triangle has one leg that measures 12 cm and a hypotenuse 24 cm. Find the length of the other leg to the nearest tenth of cent

Minchanka [31]

9514 1404 393

Answer:

20.8 cm

Step-by-step explanation:

The term "hypotenuse" suggests this triangle is a right triangle. Then the other leg can be found using the Pythagorean theorem:

x^2 +12^2 = 24^2

x^2 = 576 -144 = 432

x = √432 ≈ 20.8 . . . cm

The other leg is about 20.8 cm.

_____

<em>Additional comment</em>

A right triangle with a short leg that is 1/2 the length of the hypotenuse is the "special" 30°-60°-90° right triangle. The longer leg is √3 times the length of the short leg: 12√3 ≈ 20.8 cm.
