f(x) = x^3 + 5x^2 - 4x - 20
The zeros of the polynomial function: x^3 + 5x^2 - 4x - 20 = 0
x^3 + 5x^2 - 4x - 20 = 0
x^2(x + 5) - 4(x + 5) = 0
(x^2 - 4)(x + 5) = 0
(x + 2)(x - 2)(x + 5) = 0
(x + 2) = 0; x = -2
(x - 2) = 0; x = 2
(x + 5) = 0; x = -5
Answer is the first one
x = -5, x = -2, x = 2
The right answer is Option B: ÷ 4
Step-by-step explanation:
Given,
Number of cans used = 13
Quantity of paint in each can = 5/6 liters
Quantity of paint in 13 cans = liters
Number of cars painted = 4
4 cars =
1 car = ÷ 4
The amount of paint used for each car can be calculated by ÷ 4.
The right answer is Option B: ÷ 4

we are given
Since, we have to solve for r
so, firstly we will isolate r terms
so, we will move 12 on right side
we can add both sides by 12
now, we can divide both sides by 5
now, we can take sqrt both sides
and we get
so,
{±4}..........Answer
Answer:
5 kittens and 6 children
Step-by-step explanation:
We can use variables to find the number of kittens (K) and children (C)
each kitten will have 4 legs and each child will have 2.
You can make two equations like so:
4k+2c=32
k+c=11
You then can use the substitution method to solve for both variables:
k+c=11
Subtract k from each side:
c=11-k
Substitute this into the other equation:
4k+2(−k+11)=32
Solve for k:
4k-2k+22=32
2k=10
k=5
Then use this in one of the equations to find the other variable:
k+c=11
5+c=11
Rewrite this to make it easier:
11-5=c
c=6
k=5 and c=6
you can check this by substituting each of these value to make sure the equations are true:
k+c=11
5+6=11
11=11
4k+2c=32
4(5)+2(6)=32
20+12=32
32=32
They both check right, so
c=6 and k=5
are your answers.
There are 5 kittens and 6 children in the backyard
There is your answer
Hope this helps!
Hey there,
When finding the largest prime factor of a number, basically all you doing is find the divisible of the number. For example:
What are the prime factors of 8?
8
/ \
4 2
/ \ \
2 2 2
Hope that helps.
