<h2>
Explanation:</h2>
A parallelogram is a quadrilateral that has two pair of opposite sides and each pair measure the same. In order to illustrate this problem, see the figure below. Here we know some facts:
- Side AB measures x cm
- Side DC measures 4 cm
By definition, opposite sides in any parallelogram measure the same, so AB and DC are opposite, therefore:

Answer:
D. 25
Step-by-step explanation:
The 2 points cost Foley 2% × $100,000 = $2000. He saves $600 -520 = $80 per month, so it will take him
... $2000/($80/mo) = 25 mo
to save the cost of the points.
Answer:
16% increase
Step-by-step explanation:
A percentage change can be calculated from ...
percentage change = ((new value)/(old value) -1) × 100%
= (58/50 -1) × 100% = (1.16 -1) × 100%
= 16%

The simplified polynomial after standard form will be;
⇒ - 8x² - 43x - 36
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The algebraic expression is;
''The expression (3x + 6)² is subtracted from x² - 7x.''
Now,
We can formulate as;
⇒ (x² - 7x) - (3x + 6)²
⇒ x² - 7x - (9x² + 36x + 36)
⇒ x² - 7x - 9x² - 36x - 36
⇒ - 8x² - 43x - 36
Thus, The simplified polynomial after standard form will be;
⇒ - 8x² - 43x - 36
