Answer:
qn 10. 15mn² - 23m²n +4m³
Step-by-step explanation:
1. distribute 4m through the parenthesis
8mn² - 12m²n + 4m³ - 2n(5m² - 3nm) + nm(n-m)
2. use the commutative property to reorder the terms
8mn² - 12m²n + 4m³ - 2n(5m² - 3mn) + mn(n - m)
3. distribute -2n through the remaining parenthesis
8mn² - 12m²n + 4m³ -10m²n + 6mn² + mn² - m²n
4. collect like terms
8mn² + 6mn² + mn² - 12m²n - 10m²n - m²n + 4m³
5. complete bodmas
15mn² - 23m²n +4m³
that's is how you do it so the answer is
15mn² -23m²n + 4m³

Answer:
73 feet.
Step-by-step explanation:
Given:
A rope from the top of a pole is anchored to the ground which is 55 ft away from the base of the pole.
The pole is 48 ft tall.
Question asked:
What is the length of the rope?
Solution:
Here we found that a right angle triangle is formed in which base and height is given <u>as shown in the figure, </u>we have to find the longest side of the triangle,
Base = 55 feet
Height = 48 feet
Length of the rope = ?
By Pythagoras theorem:
Square of longest side = Square of base + Square of height
Taking root both side
Thus, length of the rope is 73 feet.
Answer:
If M is the midpoint, then LM = MN.
3x - 2= 2x +1.
x = 3.
So LM = 3x - 2 = 9 -2 = 7.
LM = 7.
