Answer:
The answer to your question is 24x³ - 46x²- 28x + 63
Step-by-step explanation:
Data
(6x² - x - 9)(4x - 7)
Process
1.- Multiply 4x by the three terms of the first polynomial
(6x² - x - 9)(4x) = 24x³ - 4x² - 36x
2.- Multiply -7 by the three terms of the first polynomial
(6x² - x - 9)(-7) = -42x² + 7x + 63
3.- Add both result
24x³ - 4x² - 36x -42x² + 7x + 63 = 24x³ - 46x²- 28x + 63
The answer is A.
1/2*12*25
6*25
150 square inches
The time spent by the repairman there will be 3 hours so the correct answer is option D.
<h3>What is an expression?</h3>
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Given that:-
A roof repairman charges a $60 consult fee, and then $45 per hour to complete repairs. if the homeowner pays a total of $195.
The time will be calculated as:-
Total amount = $195
Now the fixed consulting cost will be $60 and will be deducted from the
total amount.
Variable cost = 195 - 60 = 135
The $45 per hour charge so for $145 the time will be:-
Time = 135 / 45
Time = 3 Hours
Therefore the time spent by the repairman there will be 3 hours so the correct answer is option D.
