Two possible plans for a new bathroom are shown. Is there a value of x for which the perimeters are equal? Show your work. Expla

Dominik [7]

Answer:

There is no value of x to fit this requirement.

Step-by-step explanation:

The 2 perimeters in terms of x are:

4(x + 3) for the square and

2(x+1) + 2(x +4) for the rectangle

and these need to be equal so

we equate these 2 and solve for x:

4(x + 3) = 2(x+1) + 2(x +4)

4x + 12 = 2x + 2 + 2x + 8

4x + 12 = 4x + 10

4x - 4x = 10 - 12

0 = -2 which is of course absurd so there is no solution to this equation.

-2x + 3y = 1

Andre45 [30]

Answer:

-2x+3y =1.......(1)

y=3x-9........(2)

Now,

putting the value of y in equation (1),

-2x+3(3x-9)=1

or,-2x+9x-27=1

or,7x-27=1

or,7x=28

x= 4

Now putting the value of X in equation (2),

y=3×4-9

= 12-9

(x,y)=(4,3)

If f(x) = 4* + 12x and g(x) = 5x - 1, find (f + g)(x).

Rudik [331]

Answer:

$\large\boxed{(f+g)(x)=4^x+17x-1}$

Step-by-step explanation:

$(f+g)(x)=f(x)+g(x)\\\\f(x)=4^x+12x,\ g(x)=5x-1\\\\(f+g)(x)=(4^x+12x)+(5x-1)=4^x+17x-1$
