The volume of a cone is 164 pi cubic feet. Its height is 12 feet. Ashlyn is finding the area of the base of the cone. Her work i

s shown below.
V = one-third B h. Step 1: 164 pi = one-third pi B (12). Step 2: 164 pi = 4 pi B. Step 3: StartFraction 164 pi Over 4 pi EndFraction = B. Step 4: 41 = B.

What is Ashlyn’s error?
In step 3, Ashlyn did not subtract 4 pi from 164 pi.
In step 2, Ashlyn did not find the correct value for multiplying One-third and 12.
In step 1, Ashlyn included a factor of Pi on the right side of the formula.
In step 1, Ashlyn did not substitute the correct value for the height in the formula.

Answer:

4x^2 + 8x + 4

4(x^2 + 2x + 1) - remove GCF of 4

4(x + 1)(x + 1) - factor

4(x + 1)^2 - collect like terms

Step-by-step explanation:

Then also expand it out by distributing:

21x^3 + 35x²

Form 1:

21x^3 + 35x² - unfactored

Form 2:

7x²(3x + 5) - factored with GCF of 7x² brought to the front

Update:

You could also multiply two binomials and make a quadratic.

Example:

(7x + 2)(3x + 5)

7x(3x + 5) + 2(3x + 5)

= 21x² + 35x + 6x + 10

= 21x² + 41x + 10

Trina is purchasing a new bike the store is having 20% off sale and she as 10% coupon of the sale price if the original price of
marusya05 [52]
20% of 89.75 is 17.95
\frac{20}{100}  =  \frac{x}{89.75}  \\ x =  \frac{89.75 \times 20}{100} =  \frac{1795}{100}  = 17.95
so :
89.75 - 19.95 = 71.8
the Trina's coupon will subtract the answer by 10%:

10%of 71.8 is 7.18
\frac{10}{100}  =  \frac{x}{71.8}  \\ x =  \frac{71.8 \times 10}{100}  =  \frac{718}{100}  = 7.18
so the final answer is:
71.8 - 7.18 = 64.62
she has to pay $64.62
hope this helps
