Answer:
4 HOPE IM NOT WRONG O-O
Step-by-step explanation:
Answer:
<h2>V=1/3 pie r^2h (Formula)</h2><h2>12×22/7=1/3×22/7×3^2×h</h2><h2>Eliminate 22/7</h2><h2>12=(9×h)/3</h2><h2>Make "h" the subject of the equation </h2><h2>h=36/9</h2><h2>h=4m</h2>
He enlarged shape B by 300%
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
