Answer: D) 48.75
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Area of a rectangle: length x width
Replacing with the values given and solving for A (area)
A= 7.5 ft x 6.5 ft =48.75 ft2
The area of the garden in square feet is 48.75. (option D).

The property of equality of the rows, columns, and diagonals in the magic
square can be used to find the value of <em>n</em>.
The value of <em>n</em> is 6
Reasons:
The magic square can be presented as follows;
![\begin{array}{|c|c|c|}n-2&3&n + 2\\n + 3&n - 1&1\\2&2 \cdot n - 5&n\end{array}\right]](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7B%7Cc%7Cc%7Cc%7C%7Dn-2%263%26n%20%2B%202%5C%5Cn%20%2B%203%26n%20-%201%261%5C%5C2%262%20%5Ccdot%20n%20-%205%26n%5Cend%7Barray%7D%5Cright%5D)
Given that the sum of the numbers in each row and in each column and in
each of the two diagonals are equal, to find the value of <em>n</em>, two rows having
different number of the variable <em>n</em> can be equated as follows;
The top row = n - 2 + 3 + n + 2 = The bottom row = 2 + 2·n - 5 + n
n - 2 + 3 + n + 2 = 2 + 2·n - 5 + n
2·n + 3 = 3·n - 3
3·n - 3 = 2·n + 3 (symmetric property)
3·n - 2·n = 3 + 3
n = 6

Answer:
I bedroom condo = $280
2 bedroom condo = $400
3 bedroom condo = $560
Step-by-step explanation:
Given that :
Total rental cost for all 3 condos = $1240
Let :
I bedroom condo = b
2 bedroom condo = c
3 bedroom condo = 2b
Hence,
b + c + 2b = 1240
3b + c = 1240 - - - (1)
REPAIR COST :
Total repair cost = $276
1 bedroom = 10% of b = 0.1b
2 bedroom = 20% of c = 0.2c
3 bedroom = 30% of 2b = 0.3 * 2b = 0.6b
Hence,
0.1b + 0.2c + 0.6b = 276
0.7b + 0.2c = 276 - - - (2)
From (2)
0.7b + 0.2c = 276
0.7b = 276 - 0.2c
b = (276 - 0.2c) / 0.7
Substitute b = (276 - 0.2c) / 0.7 into (1)
3(276/0.7 - 0.2c/0.7) + c = 1240
1182.8571 - 0.8571428c + c = 1240
1182.8571 + 0.1428571c = 1240
0.1428571c = 1240 - 1182.8571
0.1428571c = 57.1429
c = 57.1429 / 0.1428571
c = 400
3b + c = 1240
3b + 400 = 1240
3b = 1240 - 400
3b = 840
b = 840/3
b = 280
Hence,
I bedroom condo = $280
2 bedroom condo = $400
3 bedroom condo = 2(280) = $560
Answer:
4
Step-by-step explanation:
First, rewrite the equation with -5 substituted for A: (-5)^2 +5(-5) +4
Next, simplify that equation: 25 -25 +4
Simplify this further: 4
When A=-5, the solution is 4.
Do we get options, or?
Um… 3/8 isn’t equivalent.
1/3 isn’t either.
There’s plenty to name that isn’t.
