Answer:
We conclude that:
Step-by-step explanation:
Given the expression
subtract 3 from both sides
Add -2² to both sides
simplify
Applying the perfect square formula: (a-b)² = a²-2ab+b²
so
∵
Therefore, we conclude that:
Answer:
Step-by-step explanation:
6 miles in 49 minutes = x miles in 1 minute
proportion time
6 x
------- = ------ cross multiply
49 1
49x = 6 ......divide both sides by 49
x = 6/49
x = 0.12244 rounds to 0.12 miles per minute <====
===============================
22 bucks for 5 hrs = x bucks for 1 hr...
22 x
------ = -------- cross multiply
5 1
5x = 22...divide both sides by 5
x = 22/5
x = 4.4.....so its $ 4.40 per hr <===
If the perimeter of the garden is (14x - 32) ft and has a side length of (x + 2) ft:
- the perimeter = 24 ft
- the area = 36 sq. ft
- if the perimeter of the garden is doubled, the perimeter of the new garden = 48 ft
- if the area of the garden is doubled, the area of the new garden = 72 sq. ft
<em><u>Recall</u></em>:
- A square has equal side lengths
- Perimeter of a square = 4(side length)
- Area of a square =
<em><u>Given:</u></em>
Perimeter of square (P) =
Side length (s) =
<em><u>First, let's find the </u></em><em><u>value of x</u></em><em><u> by creating an </u></em><em><u>equation </u></em><em><u>using the </u></em><em><u>perimeter </u></em><em><u>formula:</u></em>
- Perimeter of a square = 4(side length)
<em><u>Find how much fencing would be needed (</u></em><em><u>Perimeter </u></em><em><u>of the fence):</u></em>
- Perimeter of the fence =
Perimeter of the fence =
<em><u>Find the </u></em><em><u>area </u></em><em><u>of the garden:</u></em>
- Area of the garden =
Area =
Area =
<u><em>Find the </em></u><u><em>perimeter </em></u><u><em>if the garden size is doubled:</em></u>
- Perimeter of the new garden = 2 x 24 = 48 ft
<em><u>Find the </u></em><em><u>area </u></em><em><u>if the garden size is doubled:</u></em>
- Perimeter of the new garden = 2 x 36 = 72 sq. ft
In summary, if the perimeter of the garden is (14x - 32) ft and has a side length of (x + 2) ft:
- the perimeter = 24 ft
- the area = 36 sq. ft
- if the perimeter of the garden is doubled, the perimeter of the new garden = 48 ft
- if the area of the garden is doubled, the area of the new garden = 72 sq. ft
