(2r - 6)(-5r+4) what is the product
Akimi4 [234]

Answer:

-10r^{2} +38r-24

Step-by-step explanation:

Apply FOIL method: (a+b)(c+d)=ac+ad+bc+bd

a=2r,b=-6,c=-5r,d=4

=2r(5-r)+2r*4+(-6)(-5r)+(-6)*4

Apply minus - plus rules

+(-a)=-a,(-a)(-b)=ab

=-2*5rr+2*4r+6*5r-6*4

Simplify

Multiply -2*5rr=-10r^{2}

=-10r^{2} +2*4r+6*5r-6*4

Multiply 2*4r=8r

=-10r^{2} +8r+6*5r-6*4

Multiply 6*5r=30r

=-10r^{2} +8r+30r-6*4

Combine like terms

=-10r^{2} +38r-6*4

Multiply -6*4=-24

=-10r^{2} +38r-24

-10r^{2} +38r-24

Pulling out like terms

7.1 Pull out like factors :

8x7y2 + 18x5y3 + 6x2y4 = 2x2y2 • (4x5 + 9x3y + 3y2)

Trying to factor a multi variable polynomial :

7.2 Factoring 4x5 + 9x3y + 3y2

Try to factor this multi-variable trinomial using trial and error

Factorization fails

Final result :
2x2y2 • (4x5 + 9x3y + 3y2)

Read each relationship and decide whether its graph would be continuous or discrete
Afina-wow [57]
The ones which are discrete would have answers like 1234 and would not have any decimal answers so you can’t have half a student or half a chair there for those of the two that are discrete
