Answer:
<em>Square 4x³ - x²</em>
Step-by-step explanation:
Given the expression -5x²(4x³ - x²)²
The first step in simplifying the expression is to open the parenthesis by taking the square of 4x³ - x² as shown;
-5x²(4x³ - x²)²
= -5x²[(4x³)²- 2x²(4x³) + (x²)²]
= -5x²[16x^6- 8x^5 + x^4]
<em>Hence the correct answer is Square 4x³ - x²</em>
Answer:
The regular price was $53.85
Step-by-step explanation:
78% = $42
42 ÷ 78 x 100 = 100% = $53.85 (when rounded to 2 d.p)
Given data:
The first given length is AC=53.
The second given length is AB= 45.
The expression for the Pythagoras theorem is,
![\begin{gathered} AB^2+BC^2=AC^2 \\ (45)^2+BC^2=(53)^2 \\ BC^2=784 \\ BC=28 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20AB%5E2%2BBC%5E2%3DAC%5E2%20%5C%5C%20%2845%29%5E2%2BBC%5E2%3D%2853%29%5E2%20%5C%5C%20BC%5E2%3D784%20%5C%5C%20BC%3D28%20%5Cend%7Bgathered%7D)
Here, consider only positive sign of BC length as side cannot negative.
Thus, the BC length is 28.
