First of all, f(x) is the output,y. When you plug in 4w in x, the equation should look like this: f(x)=4w+5. Based on my understanding, the ordered pair must be (4w,4w+5). This means for each input, the output is more by 5. I hope this helps you!
A = length · width
7x3 - 42x2 = L(7x2) Factor left side
7x2(x - 6) = L(7x2) Divide both sides by 7x2
x - 6 = L
The length of the pool is x - 6.
Note: Length is always longer than width. Although the algebra is correct, it is doubtful that x - 6 is greater than 7x2.
Answer:
<h3> in square feet</h3>
Step-by-step explanation:
Area of anything is<u> allways </u>reported <u>in square units</u>. Usually that is square of given unit because it's the simplest way:
R = 50 ft
A = πR² = π•(50 ft)² = π • 50 ft • 50 ft = 2500π ft² ≈ 7854 ft²
{Of course you can re-calculate the units, ex.:
3 feet = 1 yard so 50 ft = 50/3 yd then
A = πR² = π•(50/3 yd)² = π • 50/3 yd • 50/3 yd = 2500/9 π yd² ≈ 872.7 yd² }
