Answer:

-3.6

Step-by-step explanation:

Simplifying

7 + 3x + 4 = 0

Reorder the terms:

7 + 4 + 3x = 0

Combine like terms: 7 + 4 = 11

11 + 3x = 0

Solving

11 + 3x = 0

Solving for variable 'x'.

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

Add '-11' to each side of the equation.

11 + -11 + 3x = 0 + -11

Combine like terms: 11 + -11 = 0

0 + 3x = 0 + -11

3x = 0 + -11

Combine like terms: 0 + -11 = -11

3x = -11

Divide each side by '3'.

x = -3.666666667

Simplifying

x = -3.666666667

Find the value of x.
lawyer [7]

Answer:

\huge\boxed{x=\sqrt{70}}

Step-by-step explanation:

ΔABC and ΔADB are similar (AAA).

Therefore the corresponging sides are in proportion:

\dfrac{AB}{AD}=\dfrac{AC}{AB}

Substitute:

AB=x\\AC=7+3=10\\AD=7

\dfrac{x}{7}=\dfrac{10}{x}       <em>cross multiply</em>

(x)(x)=(7)(10)\\\\x^2=70\to x=\sqrt{70}

How do I solve this?
maria [59]

14.87

Step-by-step explanation:

use the Pythagorean theorem

a^2+b^2=c^2

C being the longest side of the triangle

14^2+5^2=C^2

196+25=C^2

221=C^

find the square root of 221

C=14.866

rounded to nearest tenth

C=14.87
