Question is Incomplete; Complete question is given below.
Which expressions are equivalent to 8 (negative 10 x + 3.5 y minus 7)? Select two options. Negative 80 x + 24.5 y minus 56 Negative 80 x + 28 y minus 56 80 x + 28 y + 56 4 (negative 20 x + 7 y minus 14) Negative 4 (negative 20 x + 7 y minus 14)
Answer:
Negative 80 x + 28 y minus 56
4 (negative 20 x + 7 y minus 14)
Step-by-step explanation:
Given:
[tex]8(-10x+3.5y-7)[/tex]
We need to find the equivalent expression for given expression.
Solution:
[tex]8(-10x+3.5y-7)[/tex]
First we will apply distributive property for given expression.
[tex]a(x+y) =ax+ay[/tex]
So we get;
[tex]8\times-10x+8\times3.5y-8\times7\\\\-80x+28y-56[/tex]
Hence first expression equivalent to given expression is [tex]-80x+28y-56[/tex].
Now again evaluating the expression we get;
We will take 4 as common factor from the expression we get;
[tex]-4\times20x+4\times7y-4\times14\\\\4(-20x+7y-14)[/tex]
Hence second expression equivalent to given expression is [tex]4(-20x+7y-14)[/tex].
