Answer:
Part A: Option 2, A: Anna’s answer is incorrect. She correctly factored out 5x, but incorrectly identified a and b, so her answer cannot be correct.
Part B: Option 3, B: 5x(x+2)(x^2−2x+4)
Step-by-step explanation:
p(x) = 5x^4 + 40x
p(x) = 5x(x^3 + 8)
p(x) = 5x(x + 2)(x^2 - 2x + 4)
Part A: Option 2, A: Anna’s answer is incorrect. She correctly factored out 5x, but incorrectly identified a and b, so her answer cannot be correct.
Part B: Option 3, B: 5x(x+2)(x^2−2x+4)
<u>What we know</u>:
- Bird feeder capacity: --> 2 4/5 cups
- Samantha's scoop capacity: --> 7/10 cups
<em>Lets first convert the mixed partial fraction --> improper fraction</em>
<em> --> for easier calculation</em>
<em />
<u>After Conversion:</u>
- Bird feeder capacity: --> 14/5 cups
- Samantha's scoop capacity: --> 7/10 cups
<u>To find how many scoops of birdseed will Samantha put into the feeder we must:</u>
--> divide the total capacity by the scoop's capacity
--> find the number of scoops:
<u>Solve:</u>
![Total-number- of -scoops = \frac{\frac{14}{5} }{\frac{7}{10} } =\frac{14}{5} *\frac{10}{7} =\frac{14*10}{5*7} =\frac{14}{7} *\frac{10}{5} =2*2=4](https://tex.z-dn.net/?f=Total-number-%20of%20-scoops%20%3D%20%5Cfrac%7B%5Cfrac%7B14%7D%7B5%7D%20%7D%7B%5Cfrac%7B7%7D%7B10%7D%20%7D%20%3D%5Cfrac%7B14%7D%7B5%7D%20%2A%5Cfrac%7B10%7D%7B7%7D%20%3D%5Cfrac%7B14%2A10%7D%7B5%2A7%7D%20%3D%5Cfrac%7B14%7D%7B7%7D%20%2A%5Cfrac%7B10%7D%7B5%7D%20%3D2%2A2%3D4)
Thus the total number of scoops that Samantha will put into the bird feeder is <u>4</u>

<u>Answer: 4</u>

Answer:
Step-by-step explanation:
(5y+4+3x)(5y+4-3x) = (5y+4)² - (3x)²......(from the difference of 2 squares )
by identity : (a+b)(a-b) = a² - b²
in this exercice ; a = 5y+4 and b = 3x
Answer:
y = e^x
