Answer: 7n - 13
Step-by-step explanation:
Apply the distributive property.
4n + 3n + 3 ⋅ -5 + 2
Multiply 3 by -5
4n + 3n - 15 + 2
Add 4n and 3n
7n - 15 + 2
Add - 15 and 2
7n - 13
hope this helps :)
Answer:
48 units
b= 48 units
Step-by-step explanation:
pythag is
we have a and c
so substitute them in
now you can solve

subtract 196 from both sides
subtract
2500 - 196 = 2304
solve for the square root
square root of 2304= 48
therefore b= 48 units
The difference between the prediction & the reality is 122-57 =65 votes.
Then over 122, the error was 65 votes &
the error ratio is 65/122 = 0.5327 ==>53.27% Or 53.3% (rounded)
X^2 + 6x + 3 = 0
a=1, b=6, c=3
x1=[-6+sqrt (6^2-4*1*3)] / (2*1)
=[-6+sqrt (24)] / (2)
=-0.55
x2==[-6-sqrt (6^2-4*1*3)] / (2*1)
=[-6-sqrt (24)] / (2)
=-5.45
answer A
f(x) = 3x³ + 3x² - 6x
given the factors of the polynomial , then
f(x) =ax(x - 1)(x + 2) ( a is a multiplier )
to find a use f(2) = 24
f(2) = 2a(1)(4) = 24 ⇒8a = 24 ⇒ a = 3, thus
f(x) = 3x(x² + x - 2) = 3x³ + 3x² - 6x
