Area = length × width
Joseph: 12 × 9 = 108 feet
Alana: 25 × 7 = 175 feet
175 feet - 108 feet = 67 feet
Answer: Alana's garden is greater by 67 feet compared to Joseph's
ANSWER:
12x
“A number” just means a variable normally
Let's first add the whole numbers:
2 + 4 = 6
The LCD of 1/2 and 2/3 is 3/6 and 4/6 . . .
3 + 4 = 7
(The denominators are equal in both fractions so they will remain the same)
= 7/6
Simplifying 7/6 . . .
7/6 = 1 1/6
6 + 1 = 7
7 + 1/6 = 7 1/6
<h3>7 1/6 ← answer</h3><h3 />
<u>Your final answer is 7 1/6.</u>
I hope this helps! :)

Answer:
45. (8√2)∠π/4
46. (7√2)∠3π/4
Step-by-step explanation:
The polar form of a+bi is ...
a +bi ⇔ (√(a²+b²))∠arctan(b/a)
__
45. 8 +8i = (√(8² +8²))∠arctan(8/8) = (8√2)∠π/4
__
46. -7 +7i = (√((-7)² +7²))∠arctan(7/-7) = (7√2)∠3π/4
_____
<em>Additional comment</em>
The arctan function usually returns a value in the range -π/2 to π/2. The quadrant of the desired result can be determined by the signs of the components of the vector. For negative real parts, π needs to be added to the value that is usually returned by the arctan function.
