Answer:
c. 2a3+9a2+45a+6ab2+18b2
Step-by-step explanation:
(a+3) + (−2a2+15a+6b2)
Using distributed p. with and a and 3
a(−2a2) + a(15a) +a(6b2) and 3(−2a2) + 3(15a) + 3(6b2)
= -−2a3 + 15a2 + 6ab2 = -6a2 + 45a + 18b2
Now add like terms and put in standard form.
15a2+(-6a2) = 9a2
And equals
-2a3 + 9a2+45a+6ab2+18b2
Trust me I took the test and got 100%

Answer:
24
Step-by-step explanation:
hypotenuse (h) = 25
perpendicular (p) = 7
base (b) = ?
By using Pythagoras theorem
b = √ ( h² - p²)
=√( 25² - 7²)
= √ 625-49
= √576
= 24
The question in English
<span>Each of the 25 students in the class has made a journal on Monday. Knowing that every day a page was used and that the month is 31 days, find out how many pages the logs of all students.
</span>Let
x--------------> total students
y--------------> total days in a month
z--------------> total page used per one student in 1 day
T--------------> total page used per total students in 1 month
we know that
x=25 students
y=31 pages
z=1 page
T=[x]*[y]*[z]------------> T=[25]*[31]*[1]------------> T=775 pages
the answer is 775 pages
<span>the answer in Romanian
</span>
lăsa
x--------------> numărul total de elevi
y--------------> <span>total zile într-o lună
</span>z--------------> <span>pagina totală utilizată pentru un student în 1 zi
</span>T--------------> pagina totală utilizată pentru toți elevii în 1 lună
noi stim aia
x=25 elevi
y=31pagini
z=1 pagină
T=[x]*[y]*[z]------------> T=[25]*[31]*[1]------------> T=775 pagini
răspunsul este de 775 de pagini
