Hello!
Explanation:
Distributive property: a(b+c)=ab+ac
Multiply by the numbers.
Product it's going to be multiply by the numbers, fractions, decimals, factors, and multiples.
First, apply used their FOIL.
Foil: (a+b)(c+d)=ac+ad+bc+bd
2x*7x+2x(-6z)+5z*7x+5z(-6z)
Then you can also apply by the minus/plus sign.
2*7xx-2*6xz+5*7xz-5*6zz
And finally simplify by equation.
2*7xx-2*6xz+5*7xz-5*6zz
<em><u>Answer: =14x²+23xz-30z²</u></em>
Hope this helps!

Thanks!
11. Multiply 6 by 2. Answer is 6. Because when you multiply 8 by 2 you get 16.
12. Divide 24 by 4. You get 6. Now divide 42 by 6. The answer is 7.
P.S sorry if I'm wrong but I think I'm correct.
Minus 16x both sides and add 28 to both sides
x^2-16x+28=0
factor
hmm, what 2 numbers multiply to 28 and add to -16
hmm
1 and 28? nope
2 and 14? yep
since middle term is negative and last tem is positive, both of the factors are negative
(x-14)(x-2)=0
set each to zero
x-14=0
x=14
x-2=0
x=2
x=2 and 14
An hour is 60 minutes so 80-60 = 20 so 1 hour and 20 minutes.
