Burka [1]3 years ago
3 0

Answer:

D. 27

Step-by-step explanation:

sum of exterior angles = 360

2x + 56 + 57 + 85 + 4x = 360

6x + 198 = 360

6× = 360 - 198

6× = 162

× = 27

A submarine traveling 100 km from the shore decended 1/10 km below sea level. Then it ascended about 3/5 km the next it again de
lyudmila [28]

Answer:

Horizontal displacement = 100 km

Position with respect to sea level = -0.4km

Step-by-step explanation:

Let the displacement downwards be negative displacement and displacement upwards be positive.

The horizontal distance from the shore remains constant whereas the displacement from the sea level varies as the submarine moves.

The upward displacement = 3/5 km

Downward displacement = - 1/10 km and - 9/10 km

Total displacement = 3/5km - 1/10 km - 9/10km = - 2/5 km = - 0.4 km

Horizontal distance from the shore = 100km

What is the answer to x^2-11=25 please
Westkost [7]

Hey there!

\mathsf{x^2 - 11 = 25}

\large\textsf{ADD 11 to BOTH SIDES}

\mathsf{x^2 - 11 + 11 = 25 + 11}

\large\textsf{CANCEL out: -11 + 11 because that gives you 0}

\large\textsf{KEEP: 25 + 11 because that helps solve for the x-value}

\mathsf{25 + 11 = \bf 36}

\large\textsf{NEW EQUATION: }\mathsf{x^2=36}

\large\textsf{Take the square root of the number (36)}

\mathsf{x = \pm \sqrt{36}}

\mathsf{\pm = \boxed{\bf plus-or-minus}}

\mathsf{x = \sqrt{-36}\rightarrow \bf -6}

\large\textsf{or}

\mathsf{x = \sqrt{36} = \bf 6}

\boxed{\boxed{\huge\textsf{Answer: \bf x = 6 or x = -6}}}\huge\checkmark

\large\text{Good luck on your assignment and enjoy your day!}
