What value of x makes the equation true? 1/2(4x−5)+52=10

Anon25 [30]

Answer:

x = -19.75

Step-by-step explanation:

$\frac{1}{2}(4x-5) +52 =10$

$\frac{4x-5}{2}+ 52 = 10$

$\frac{4x-5+ 52\times 2}{2} = 10$

$4x-5+ 104 = 10 \times 2$

$4x+99 = 20$

$4x = 20-99$

$4x = -79$

$x= -\frac{79}{4}$

$x= -19.75$

Find the length of the altitude to the hypotenuse. round the answer to the nearest tenth, if needed.

Amiraneli [1.4K]

Answer : The correct option is, (B) 56.8

Step-by-step explanation :

Right Triangle Altitude Theorem:

The measure of altitude drawn from the vertex of the right angle of a right angled triangle to its hypotenuse is the geometric mean between the measures of the two segments of the hypotenuse.

We are drawing a line from vertex to hypotenuse side.

As per theorem:

$\frac{BD}{AB}=\frac{CB}{AC}$

$\frac{BD}{60}=\frac{175}{185}$

$BD=\frac{175\times 60}{185}$

$BD=56.8$

Therefore, the length of the altitude to the hypotenuse is 56.8

Pls answer! i will mark brainliest!

Volgvan

Answer:

3 inches

Step-by-step explanation:

(14+2x) × (15+2x) = 2(14×15)

210 +30x +28x + 4x² = 420

4x² + 58x - 210 = 0

2x² + 29x - 105 = 0

2x² + 35x - 6x - 105 = 0

x(2x + 35) - 3(2x + 35) = 0

(x - 3)(2x + 35) = 0

x = 3, -35/2(not possible)
