Answer:
(B) 18.
Step-by-step explanation:
We are asked to find the perimeter of a quadrilateral with vertices at (-1, 4), (7,4), (7,5), and (-1. 5).
First of all, we will draw vertices of quadrilateral on coordinate plane and connect the vertices as shown in the attached photo.
We can see that our quadrilateral is a parallelogram, whose parallel sides are equal.



Therefore, the perimeter of the given quadrilateral is 18 units.

Answer:
0.21875
Step-by-step explanation:
We can find the percent of a number by multiplying the number by 0.25 after converting the number from a fraction to a decimal.
7/8=0.875
0.875(0.25)=0.21875
If the variable x is a positive integer, the list of possible values of x can be represented as; x >=1.
<h3>Positive integers</h3>
According to the question;
- We are required to list the possible values of x provided the variable x is a positive integer.
On this note, the list of possible values of x is all numbers greater or equal to 1 in which case these numbers do not have a fractional component.

If you are looking to simplify these equations, here is how you would go about doing so.
7w(-8+3w)
Use a property called the Distributive Property, which means multiplying the number outside of the bracket by each number inside of the brackets.
Here is how this would look:
7w(-8+3w)
-56w+21w²
Now,
6q(-4+8q)
-24q+48q²
Hope this helps.
