What is the factored form of this expression? 5p^3-10p^2+3p-6
Answer:
[tex](5p^2+3)(p-2)[/tex]
Step-by-step explanation:
In this problem, we need to write the factor form of expression [tex]5p^3-10p^2+3p-6[/tex].
It can be done as follows :
[tex]5p^3-10p^2+3p-6=(5p^3+3p)+(-10p^2-6)[/tex]
Taking common form the terms as follows :
[tex]=p(5p^2+3)-2(5p^2+3)[/tex]
It can be also written as :
[tex]=(5p^2+3)(p-2)[/tex]
Hence, the factored form of [tex]5p^3-10p^2+3p-6[/tex] is [tex](5p^2+3)(p-2)[/tex]
Answer: (p-2)(5p^2+3)

3b+4-1b+3 what is the answer please help
Answer:
2b +7
Step-by-step explanation:
We assume you want to simplify this expression. It can be helpful, though is not required, to group like terms near each other.
= 3b -1b +4 +3
= b(3 -1) +(4 +3) . . . combine like terms
= 2b +7
If f(x) = x2 + 4x - 12, find f(2).
Answer:
-3
Step-by-step explanation:
Please write this as f(x) = x^2 + 4x - 12. "x^2" represents "the square of x."
f(2) is the value of this function when x = 2:
f(2) = f(2) = (2)^2 + 4(2) - 12 = 9 - 12 = -3

ITS BEEN AN HOUR LS ILL GIVE BRAINLITST
Answer:
38.81%
Step-by-step explanation:
Circle area = п r ²
п = 3.14
r = 4 cm
Circle area = 3.14 * (4cm)²
Circle area = 3.14* 16cm²
Circle area = 50.24cm²
Triangle area = (heigth*width)/2
heigth = 2.5 + 4 = 6.5cm
width = 3 + 3 = 6cm
triangle area = (6.5cm*6cm)/2
triangle area = 39cm²/2
triangle area = 19.5cm²
then:
the probability that a randonly select point whitin the circle falls in the shaded area is:
19.5/50.24 = 0.3881 (aprox)
0.3881*100 = 38.81%

9x^2 - 16 = (px+t)(px-t) both p and t are constants. Which of the following could be the value of p
Answer:
p = 3
Step-by-step explanation:
9x² - 16 ← is a difference of squares and factors in general as
a² - b² = (a + b)(a - b)
Thus
9x² - 16
= (3x)² - 4²
= (3x + 4)(3x - 4)
Compare with (px + t)(px - t)
then p = 3

I'm working with varibles on both sides. This is math, also algebra 1. The expression is... 8-4a=16-8a I'm so confused on which side to subtract from. I tried doing +8 on both sides. Please help.
Answer:
a=2
Step-by-step explanation:
You can have "a" on both sides and still get an answer easily. You start off by adding 8a to the right. That makes 8+4a=16. You then subtract 8 from 16 and get 4a=8. Divide by 4 to get your answer. You get a=2

True or False: by using the additive inverse property -64 - (-17) can be rewritten as -64 + 17
Step-by-step explanation:
Additive inverse is when you have a positive number, for example, and it becomes a negative.
Example: 8
The additive inverse of 8 is -8.
So the answer is false.
-64+17 and -64-(-17) is an example of communative property.
Hope it helps!

p1 + 2q = 3,
p - 2q = 3
Answer:
q-0
p-3
Step-by-step explanation:
there are two ways to solve elimination or substitution method I'll use the latter
so take the second equation and find an expression equal to p
p-2q=3
p=2q+3
substitute the above expression in the first equation
(2q+3)1+2q=3
open brackets
2q+3+2q=3
collect like terms
4q+3=3
solve
4q=0
q=0
substitute q in any equation you want I'll choose the second
p-(2×0)=3
p-0=3
p=3
Answer:
p = 3 ; q = 0
Step-by-step explanation:
In this linear pair of eqn. in 2 variables , they have a unique solution i.e. they will have only single solution . We know that
[tex]p + 2q=3[/tex] & also [tex]p -2q=3[/tex] . So, we can also equate them as :-
[tex]p + 2q = p-2q[/tex] (∵ Both the eqn. have 3 in their right hand side product )
Solving the eqn. gives,
[tex]=> 2q + 2q = p-p\\=> 4q=0\\=>q=0[/tex]
Putting the value of q in any one of the linear eqn gives ,
[tex]p+2q=3\\=> p+2(0)=3\\=>p+0=3\\=>p=3[/tex]

What is Least Common Multiple(LCM)?The least common multiple is defined as the least positive integer that is dividable by both given numbers.
A group's Least Common Multiple (LCM) is the smallest number that is a multiple of all the numbers. For example, the LCM of 4 and 5 is 20; 20 is the smallest number that is both a multiple of 4 and a multiple of 5
To solve this problem, we need to find the least common multiple (LCM) of the two sequences of days, 3 and 4.
The LCM of 3 and 4 is 12, which means that after every 12 days, Max and Ellen will both be at the gym on the same day.
Starting from Monday, the next time Max and Ellen are at the gym together will be 12 days later, which is a Saturday.
Hence, the answer is an option (D) Saturday.
