Part A:
The total area = x² + 12x + 20 = (x+2)(x+10)
<span>The width = x+2
∴ Length = area / width = </span>[ <span>(x+2)(x+10) ] / (x+2) = x+10
Part B: </span>
<span>A 2-foot walkway is built around the fountain
</span>
<span>∴ The width = (x+2) + 2 + 2 = x + 6
The length = (x+10) + 2 + 2 = x +14
Part C:
</span><span>the total area covered by the fountain and walkway.
</span><span>
= (x+6)(x+14)
= x² + 20 x + 84
See the attache figure for more explanation

Answer:
32
Step-by-step explanation:
2 to the power of 2 is 4
12×(3+4)÷2-10
12×7÷2-10
84÷2-10
42-10
ANS=32
they increased by 70 percent. divide 667 by 912 and you get 0.67237903 but you round to the tenths and get 70% because you move the decimal to the right twice
F ( x ) = k * x²
f ( 4 ) = 96
96 = k * 4²
96 = 16 k
k = 96 : 16
k = 6
f ( 2 ) = 6 * 2² = 6 * 4 = 24
ANSWER D
Answer:
Area of Living Room = 300 square feet
Step-by-step explanation:
According to question ,
The area of bathroom = 35 square feet
And it is mention that area of bathroom is 25 sqft less than area of living room .
Thus , as per question ,
Area of bathroom = times area of living room - 25 sqft
Or, 35 sqft = times area of living room - 25 sqft
Or, 35 sqft + 25sqft = times area of living room
Or, 60 sqft = times area of living room
∴ Area of living room = 60 × 5
Hence , Area of living room = 300 square feet .
