Answer:

a=7,\\b=3

Step-by-step explanation:

The area of a rectangle is equal to A=l\cdot w, where l is the length of the rectangle and w is the width of the rectangle. In a rectangle, opposite sides are equal.

Therefore, we can write the following system of equations:

\begin{cases}a\cdot (9+b)=84,\\a\cdot b=21\end{cases}

Expand the first equation:

9a+ab=84

Substitute the second equation into the first (ab=21):

9a+21=84,\\9a=63,\\a=\boxed{7}

Solving for b:

7b=21,\\b=\frac{21}{7}=\boxed{3}

True or false m angle 5 is greater than m angle 8​
My name is Ann [436]

Answer:

True

Step-by-step explanation:

You can see that Angle 5 is slightly greater than 90°, so it is obtuse

Angle 8 is less than 90°, and is acute

Since obtuse angles are larger than acute angles, Angle 5 is greater than Angle 8.

If my answer is incorrect, pls correct me!
