How do you factor x^2-5x+4 for the answer

Hi there!
In order to factor, start by knowing the variables for each term in the equation ax^2+bx+c
A=1
B=-5
C=4
(Based on the given equation)
In order to factor, we need to find two numbers that add to the b term (-5) but multiply to the c term (4)
-4*-1=4
-4+-1=-5
Therefore, the factored form would be y=(x-4)(x-1)

Hope this helps!

Yal my someone please help me with this, its teh last thing
USPshnik [31]

1) 2 1/3 is also equal to 7/3

4 1/5 is also equal to 21/5

you need to make the denominators the same so you have to find the lowest common multiple, which is 15 since both 5 and 3 can be times by to make 15

you need to also times the numerators by the number you're timesing the denominator by

7/3 x 5 = 35/15

21/5 x 3 = 63/15

now add those together

35/15 + 63/15 = 98/15

now just convert 98/15 back to a mixed fraction

98/15 = 6 8/15

the answer is..

6  \frac{8}{15}

I'll do the others in a different answer!!

Firefighters need to use a 60-foot ladder to save a child. She is 50 feet above street
mr_godi [17]

Answer:

The ladder must be placed at a distance of 33.2 feet from the bottom of the building

Step-by-step explanation:

From what we have here, we are looking at a right angled triangle with the hypotenuse which is the length of the ladder

The height of the child is 50 feet from ground level

So we need to get the third side of the triangle

We can get this by considering the use of Pythagoras’ theorem

This will give us the length of the third side of the triangle

From Pythagoras’ the square of the hypotenuse is equal the sum of the squares of the two other sides

Let the unknown side be x

Thus;

60^2 = 50^2 + x^2

x^2 = 60^2 - 50^2

x^2 = (60-50)(60+50)

x^2 = (10)(110)

x^2 = 1100

x = square root of 1100

x = 33.166

To the nearest tenth, this is 33.2 feet
