Simplify (2x+5y)(3x-8y)

= − xy −

Step-by-step explanation:

{Apply\:FOIL\:method}:\quad

\left(a+b\right)\left(c+d\right)=ac+ad+bc+bd

a=2x,\:b=5y,\:c=3x,\:d=-8y

{Apply\:minus-plus\:rules}

+\left(-a\right)=-a

=2\cdot \:3xx-2\cdot \:8xy+5\cdot \:3xy-5\cdot \:8yy

Simplify 2 · 3xx − 2 · 8xy + 5 · 3xy − 5 · 8yy: 6x − xy − 40y

2 2

= − xy −

Hope This Helps!

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
