Answer:
See below
Step-by-step explanation:
<u>Given function</u>
<u>We can find its factors:</u>
- x³ + 3x² - 7x - 21 =
- x²(x + 3) - 7(x + 3) =
- (x² - 7)(x + 3)
We can conclude that the given polynomial function is fully divisible by (x + 3) and the quotient is (x² - 7)
Also one of zeros of the function is -3
Answer:
499
Step-by-step explanation:
9,999 would be the greatest value
9500 would be the smallest value
if you subtract them you'll get 499
Answer:
Boys(B) + Girls(G) = 85 ----(1)
Mangoes = 380
Each boy gets 4mangoes
Each girl gets 5mangoes
4B + 5G = 380 -------(2)
from (1) B = 85 - G
Substitute B in (2)
4(85 - G) + 5G = 380
360 - 4G + 5G = 380
G = 380 - 360 = 20
from (1) B = 85 - 20 = 65
Therefore number of boys = 65 and girls = 20
Ratio of boys and girls = 65 : 20 = 13 : 4
F because, if you take 270/450=.6 or 60% and that would be your p, and 60%/100=.6

Sua matemática seria:10.8 * 3 = 32.4
32.4 + 32.4 + 10.8 + 10.8 = 86.4
86.4 * 130 = 11,232
11,232 - 10,000 = 1,232Você precisará de mais 1,232 tijolos para concluí-lo.
Eu espero que isso ajude :)
