5 0

   6a + 3b - 4a - 5b

Gather the a's and b's together: 6a - 4a   +   3b - 5b

Add up the a's :    2a     + 3b - 5b

Add up the b's : 2a    + -2b

There you are:    2a - 2b

The rectangle below has an area of 14x^4+6x^214x 4 +6x 2 square meters. The width of the rectangle (in meters) is equal to the g

valina [46]

Answer:

Width = 2x² , Length = 7x² + 3

Step-by-step explanation:

The area of the rectangle = 14x⁴ + 6x²

The width of the rectangle (in meters) is equal to the greatest common monomial factor of 14x⁴ and 6x²

Factors of 14: 1 * 2 * 7

Factors of 6: 1 * 2 * *3

∴ The greatest common monomial factor of 14 and 6 = 2

Factors of x⁴: x , x² , x³ , x⁴

Factors of x²: x , x²

∴ The greatest common factor of x⁴ and x² = x²

∴ Width = 2x²

∵ Area = length times the width

∴ Length = Area/Width

Length = $\frac{14x^{4}+6x^2 }{2x^2} =\frac{2x^2*(7x^2+3)}{2x^2} =7x^2+3$

Answer:

Step-by-step explanation:

7e^x=343

/7 /7

e^x=49

By trial and error, x must be between 3 and 4, but closer to 4.

Further trial and error says x must be between 3.8 and 3.9, but closer to 3.9

Another trial and error says x must be between 3.89 and 3.9.

The closest answer I got was 3.891821
