Answer:

Area of walkway = 16(x+4) ft^{2}

Step-by-step explanation:

Length of the sides of the square outdoor = x feet

Area of the square outdoor = length x length

                            = x * x

                            = x^{2} ft^{2}

The square outdoor is surrounded by 4 feet of walkway. So that,

length of the walkway = (x + 2(4))

                                     = (x + 8)

Area of walkway with outdoor = (x + 8)*(x + 8)

                                      = (x^{2} + 16x + 64) ft^{2}

Area of walkway = Area of walkway with outdoor - Area of the square outdoor

                            = ( x^{2} + 16x + 64) - x^{2}

                            = 16x + 64

Area of walkway = 16(x+4) ft^{2}

How many roots does the equation 3x² = 1 - 7x have and what is the nature of the roots
AnnyKZ [126]

Answer:

Step-by-step explanation:

Rewrite this quadratic in standard form:  3x^2 + 7x - 1.

The coefficients of x are {3, 7, -1}, and so the discriminant is b^2 - 4ac, or

7^2 - 4(3)(-1), or 49 + 12, or 61.  Because the discriminant is positive, this quadratic has two real, unequal roots

Find the range of the function y= 9x-2, where x>-2
RideAnS [48]

Answer:The given function is .Minimum or maximum value:At the extremum (maximum or minimum) value, the function will have zero slope. So, differentiate the given function once and equate it to zero to get the extremum point.dy/dx=0Now, check whether the point x=0 is corresponding to the maximum value or minimum value by differentiating the function twice,As  for all value of x, so x=0 is the point corresponding to minima.Put x=0 in the given function to get the minimum value.Domain and range:The function defined for all the values of the independent variable, x.So, the domain is .The range of the function is the possible value of y.The minimum value, for x=0, is y=7.The maximum value, as .Hence the range of the function is .The value of x for which the function is increasing and decreasing:If the slope of the function is negative than the function is decreasing, soThen, from equation (i), the value of x for which dy/dx<0,18x<0Hence, the function is decreasing for  .While if the slope of the function is positive than the function is increasing, soThen, from equation (i), the value of x for which dy/dx<0,18x>0Hence, the function is increasing for
