Area is length times width in this scenario. The length is going to increase by 3; this can be expressed by the term L+3. The width is 5, but the total area is going to be 90. Your expression should look like this:
5(L+3)=90
First, multiply the 5 on the left side of the equation.
5L+15=90
Subtract 15 from both sides to get the coefficient and the variable by itself.
5L=75
Divide by 5 on both sides to get the variable alone.
L=15
You're not done yet. Remember, you must add 3 back into L to get the new length. The original garden would have been 15 meters in length, but the new length of the new garden will be 18 meters.
To check this, use the formula for area.
18(5)=90
90=90
Answer:
3x^2+3x+2

Answer:
101
Step-by-step explanation:
3 -1i + 21i -7i2 now you have to fix the last factore because you have to change the imaginery i this would give you the answer of 3 - 1i + 21i +7 now add common factor which would give you the final answer of 3 +20i +7
Part 1: Circumference of circle = 
inches & Area of circle = 
Part 2: Area of circle = 
Part 3: Area of square not covered by circle = 
.
<u>Step-by-step explanation:</u>
<u>Part 1:</u>
We have radius of circle as 
. Let's find area & circumference of circle:
Circumference of circle = 
⇒ Circumference of circle =
⇒ Circumference of circle = = 
⇒ Circumference of circle = inches
Area of circle = 
⇒ Area of circle=
⇒Area of circle = = 
⇒ Area of circle =
<u>Part 2:</u>
Circumference of circle = = 
⇒ 
⇒ 
Area of circle =
⇒Area of circle = = 
⇒ Area of circle =
<u>Part 3:</u>
Perimeter of square = 
, a is side of square.
⇒ 
⇒ 
⇒ a = 
Since radius of circle inscribed in square is half of side of square i.e.
Now, Area of square not covered by circle = Area of square - area of circle
⇒ 
⇒ 
⇒
∴ Area of square not covered by circle = .
