Step-by-step explanation:
(3x2)(−2x4) = 3(−2)x2∙4 = 6x8 can you find whats wrong with this problem
Answer:
the equal sign
Step-by-step explanation:
The final correct result is:[tex](3x^2)(-2x^4) = -6x^6[/tex]
Given that:
The expression: [tex](3x^2)(-2x^4) = 3(-2)x^{2\times4} = 6x^8[/tex]
The error is in the second step of the simplification:
[tex](3x^2)(-2x^4) = 3(-2)x^{2\times4} \\(3x^2)(-2x^4) = 6x^8[/tex]
[tex](3x^2)(-2x^4) = 3(-2)x^{2\times4} = 6x^8[/tex]
The second step is incorrect. The correct rule for multiplying powers with the same base is to add the exponents, not multiply them.
Here, add the power of x is 2 and 4, that is,
2 + 4 = 6
And multiply the coefficient of x as:
The coefficient of x are 3 and (-2).
So, the multiplication as:
3 × (-2) = -6
The correct simplification should be:
[tex](3x^2)(-2x^4) = 3\times(-2) \times x^{2+4}\\(3x^2)(-2x^4) = -6x^6[/tex]
So, the multiplication as:
3 × (-2) = -6
So, the final correct result is:
[tex](3x^2)(-2x^4) = -6x^6[/tex]
Hence, the error occupied in second step.

Josh works for a construction company that uses 150 pounds of gravel for each driveway they pour.
He can buy a dump truck load with 30,000 pounds of gravel or a pick-up truck load with 2,500 pounds.
Which amount should he buy so that no gravel is left after all of the driveways are poured and why?
A.
Josh should buy the pick-up truck load because 2,500 ÷ 150 = 16 23. There is enough gravel to
pour 16 driveways with 100 pounds of gravel left. You cannot divide 30,000 ÷ 150 evenly.
B.
Josh should buy the pick-up truck load because 2,500 ÷ 150 = 160 23. There is enough gravel to
pour 160 driveways with 100 pounds of gravel left. You cannot divide 30,000 ÷ 150 evenly.
C.
Josh should buy the dump truck load because 30,000 ÷ 150 = 200. There is enough gravel to
pour 200 driveways with none left. You cannot divide 2,500 ÷ 150 evenly.
D.
Josh should buy the dump truck load because 30,000 ÷ 150 = 2,000. There is enough gravel to
pour 2,000 driveways with none left. You cannot divide 2,500 ÷ 150 evenly.

Is this right? I chose 15.
Answer:
Correct, it is 15
Step-by-step explanation:
Because 3 turns into 9, you also want to multiply the other by 3, so you’d do 5x3 to get 15
Answer:yes you are correct. The answer is 15
Step-by-step explanation:
You would have to do 9/3=x/5. If you simplify that it would be 3x=45. If you simply further, you would get x=15 so yes you are correct.

Ziann’s weekly earnings were proportional to the number of hours she worked. This table shows the number of hours Susan worked and the amount she earned.
How much money did Ziann earn per hour?
Answer:
Can't answer.
Step-by-step explanation:
We know that Ziann's earnings were proportional to the hours she worked, but the table shows how much Susan earned, so we don't know how much Ziann earned. We are not told that Ziann and Susan are the same person.
Susan's earnings:
$47.50/(5 hours) = $9.50/hour
According to the table, Susan earned $9.50 per hour.

A rectangle has an area of 12 square centimeters and a perimeter of 16 centimeters. which of the following couldd be its dimensions?
a. 2 cm and 6 cm
b. 3 cm and 8 cm
c. 1.5 cm and 8 cm
d. 1 cm and 12 cm
Answer:
a 2 cm and 6 cm
Step-by-step explanation:
The product of the dimensions must be 12 cm². (All answer choices meet that requirement.)
Opposite sides of a rectangle are the same length, so the sum of the two dimensions must be half the perimeter, 8 cm. The sums of the answer choices are ...
8 cm
7 cm
9.5 cm
13 cm
Only the first answer choice meets the requirement for a perimeter of 16 cm. The dimensions could be 2 cm and 6 cm.
Answer:
A. 2 cm and 6 cm 6*2=12 (area)
2+2+6+6=16
