We actually need the choices but oh well, we can simpify and hopefuly it is one of the choices
remember the distributive property
a(b+c)=ab+ac
so
7(p+2n)+n
distribute first
7(p)+7(2n)+n
7p+14n+n
7p+15n is an equivilent expression
Jessica bought 2.25 yards more material than Derek. Hope this helped!
is the same thing as
. We can rewrite this as
. Or course this is not simplified, so we can simplify to get
.
A. -4ac
-4(2)(-3)
multiply
-4(-6)
multiply, again
24
b. -4ac
-4(-4)(-2)
multiply
-4(8)
multiply, again
-32
c. -4ac
-4(-1)(5)
multiply
-4(-5)
multiply, again
20
