What is the value of x in the diagram below? Id necessary, round your answer to the nearest tenth of a unit.

D

Step-by-step explanation:

This uses the Altitude- on- Hypotenuse theorem

An altitude drawn to the hypotenuse of a right triangle.

The 2 triangles formed are similar to the given triangle and each other, thus

Δ BAC ~ Δ BDA

The ratios of corresponding sides are equal, that is

= , substitute values

= ( cross- multiply )

30x = 196 ( divide both sides by 30 )

x ≈ 6.5 ( to the nearest tenth ) → D

idk this answer sorry cant on this one.

step-by-step explanation:

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.
