Answer:
The answer is C
Step-by-step explanation:
The answer is 21
First you po perenthies which would be 8-6=2 the equation now is 5+4×(2)2
Then you to exponents which would be 2×2=4 the equation now is 5+4×4
Now you multiply 4×4=16 the equation is now 5+16
Now you add 5 and 16 to get 21

Answer:$430
Step-by-step explanation: 40*4 for the first amount of cloth, 6*45 for the second amount. Add those two together and you get 430
The second-degree polynomial function f(x) that has a lead coefficient of 4 and roots 5 and 2 is f(x) = 4x² -28x + 40. The correct option is the last option f(x)=4x²-28x+40
<h3>Quadratic equation</h3>
From the question, we are to determine which second-degree polynomial function f(x) has a lead coefficient of 4 and roots 5 and 2
To determine this, we will use the given roots to determine the equation
The roots are 5 and 2
Thus
x = 5 and x = 2
x - 5 = 0 and x - 2 = 0
Therefore,
(x -5)(x -2) = 0
Distributing
x(x -2) -5(x -2) = 0
x² -2x -5x + 10 = 0
x² -7x + 10 = 0
Now, multiplying through by 4, we get
4x² -28x + 40 = 0
Thus, the function becomes f(x) = 4x² -28x + 40
Hence, the second-degree polynomial function f(x) that has a lead coefficient of 4 and roots 5 and 2 is f(x) = 4x² -28x + 40. The correct option is the last option f(x)=4x²-28x+40
