What is the factorization of the following trinomial? 15x2 - 44x - 36

1 answer:

7 0

$15x^2-44x-36$

$=(15x^2+10x)+(-54x-36)$

factor out 5x from $15x^2+10x = 5x(3x+2)$

Factor out -18 from $-54x-36 = -18(3x+2)$

$=5x(3x+2)-18(3x+2)$

Factor out common term $(3x+2)$

$= (3x+2)(5x-18)$

hope this helps!

Could y’all help me out with this?

Aneli [31]

Answer:

M' (5,-1)

D' (5,1)

A' (3,4)

W' (4,-1)

Step-by-step explanation:

We want to find the coordinates of Quadrilateral MDAW with vertices M(-1, 5), D(1,5), A(4,3), and W(-1,4) after a reflection across y = x.

We can find these coordinates by following the following rule:

Reflection over y = x rule : ( x , y ) ---> ( y , x )

Explanation of rule: Simply swap the places of the x and y values.

Applying rule to given coordinates:

M(-1,5) -----> swap x and y values -----> M'(5,-1)

D(1,5) ----> swap x and y values -----> D'(5,1)

A(4,3) -----> swap x and y values -----> A'(3,4)

W(-1,4) -----> swap x and y values -----> W'(4,-1)

So the coordinates of Quadrilateral MDAW after a reflection over the y = x line are M'(5,-1) , D'(5,1) , A'(3,4) , W'(4,-1)

What will you get when you add two integers

Well, it depends if its positive or negative. 2 positive integers will equal a positive, 2 negatives will equal a negative. A negative and a positive will depend.

mixer [17]

<span>You need to set up 2 equations for this, a system to be exact let x represent the cheaper phone and y represent the upgraded phone for store costs you will have 5x+25y=200 for selling prices you will have 30x+100y=900 set these two equations together 5x+25y=200 30x+100y=900 multiply the first one by -4 and add them -20x-100y=-800 30x+100y=900 10x=100 x=10 10 cheaper phones, plug into any equation again 5(10)+25(y)=200 y=6<<<6 upgraded phones</span>
