Answer this question showing work. 2b − 7 ≥− 14 + 2b
jeka94

Answer:

No solution

Step-by-step explanation:

This answer has no solution, follow these steps to see how.

First, you add 7 on both sides.

Then you should have 2b > -7 +2b

You see how there is a 2b on both sides? this makes the problem unsolvable.

Say you were to continue though. You would subtract 2b on both sides and end up getting 0 > -7.  Therefore there is no solution.

marissa [1.9K]
To find the length of the altitude, we have to use the ratios of the similar sides.
Let the length of altitude=x
Ratio of sides:
\frac{x}{3} = \frac{27}{x}  \\
Cross \ multiply \\
 x^{2} =81 \\
Take \ square \ root.\\
 \sqrt{x^2}= \sqrt{81} \\
x=9 \\
So length of altitude is 9 cm.
