The square has a side length of 9.
The area of the full square would be 9^2 = 9 x 9 = 81 square cm.
The area of the triangle is 1/2 x 4 x 3 = 6 square cm.
The area of the shape = 81 -6 = 75 square cm.
Answer:
A) By using the Pythagorean Theorem, we will see that
. If we simplify it, we will find that the hypotenuse of Δ
B) approximately 
Step-by-step explanation:
A) In all honesty, you don't really need to look at ΔACD at all for this one. Just use the Pythagorean Theorem (like previously stated) and solve!
***Pythagorean Theorem is 
B) Here, you can also use the Pythagorean Theorem! However this time, the equation will be,
.
≈ 
Hope you do well on the rest of your math problems :D
Hello, Marymack!
We know that in a geometric sequence defined by

and

, the sum can be calculated the following way:
You can just google this, here is what popped up when I searched it so I could give an exact answer..... Variability<span> is the extent to which data points in a statistical distribution or data set diverge from the average, or mean, value as well as the extent to which these data points differ from each other. There are four commonly used measures of </span>variability<span>: range, mean, variance and standard deviation.</span>
