Please plis help me with this equation is for tomorrow put with resolution plis which are in parentheses and written: "squared"
is because the parenthesis set is raised to the square thanks
(x+5) (2x-12) =
(5x squared + x) (3x cubed - 1) =
(3x+1) (x+3) - (3x+2)(x+2)=
M= (4x+1)squared - 2(8x squared + 4x)
(x+5) (2x-12) =
(5x squared + x) (3x cubed - 1) =
(3x+1) (x+3) - (3x+2)(x+2)=
M= (4x+1)squared - 2(8x squared + 4x)

Answer:
A) speed = 10.5 miles per hour
B) Time taken by him = 1.714 hours
C) Distance = 10.5 mph × 7 hours = 73.5 miles
Step-by-step explanation:
Given as :
The distance cover by David = miles = 5.25 miles
The time taken by David = hours = 0.5 hours
Let the speed = x mile per hour
So, Distance = Speed × Time
A)or, Speed =
Or, Speed =
∴ speed = 10.5 miles per hour
<u>B) Again The Distance cover by him = 18 miles</u>
SO, with speed 10.5 miles per hour
The Time taken by him = hours
Or, Time taken by him = hours
∴ Time taken by him = 1.714 hours
<u>C) Again the Time taken by him = 7 hours </u>
So, Distance cover by him with speed 10.5 mph
Or, Distance = 10.5 mph × 7 hours = 73.5 miles
A) speed = 10.5 miles per hour
B) Time taken by him = 1.714 hours
C) Distance = 10.5 mph × 7 hours = 73.5 miles Answes
<u><em>Answer:</em></u>
5n-4
<u><em>Explanation:</em></u>
<u>The given expression is:</u>
<u>1- Take the negative as a common factor from both the numerator and the denominator. This will give us:</u>
<u>2- Cancel out the negative sign (common factor) from the numerator and denominator. This will give us:</u>
<u>3- Factor the numerator. This wil give:</u>
<u>4- Finally, cancel out the (17n+19) which common in both numerator and denominator. This will give us the final expression:</u>
5n-4
Hope this helps :)
