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:

We need to find the equivalent expression for given expression.
Solution:

First we will apply distributive property for given expression.

So we get;

Hence first expression equivalent to given expression is
.
Now again evaluating the expression we get;
We will take 4 as common factor from the expression we get;

Hence second expression equivalent to given expression is
.

Answer:
c =
km
Step-by-step explanation:
Here's the required formula to find the missing side of triangle by pythagoras theorem :

a = 20 km
b = 21 km
c = ?
Substituting all the given values in the formula to find the third side of triangle :

Hence, the length of missing side of triangle is 29 km.

H(x) = x - 5
However, it had a domain of all real numbers such that x does not equal 3, since that would cause you to divide by 0.
