Answer:

12 feet × 4 feet

Step-by-step explanation:

x² + 8x - 48 = 0

x² + 12x - 4x - 48 = 0

x(x + 12) - 4(x + 12) = 0

(x - 4)(x + 12) = 0

x = 4, -12

x = 4

New dimensions:

4 + 8 = 12

48/12 = 4

Answer:

4 ft by 12 ft

Step-by-step explanation:

x^2 +8x -48

Set this equal to 0 to solve for the values of x

x^2 +8x -48=0

What two values multiply to -48 and add to 8

12*-4 = -48

12+-4 = 8

(x+12) (x-4) = 0

Using the zero product property

x+12 = 0   x-4=0

x=-12           x=4

We cant have a negative length

x=4

The area is 48

48/4 = 12

The other dimension is 12

GrogVix [38]

7:56

Figure out what 7/3 is so you can multiply 24 by that number. Is is 2 1/3 so when you multiply 2 1/3 by 24 it gets you to 56 so the proportion is 7:56

Solve for w. 5w + 9z = 2z + 3w w = w equals negative StartFraction 7 Over 2 EndFraction z.Z w = w equals negative StartFraction
TEA [102]

Answer:

w = -7z/2

Step-by-step explanation:

We need to solve for w in terms of z.

The equation given is:

5w + 9z = 2z + 3w

Collect like terms:

5w - 3w = 2z - 9z

2w = -7z

w = -7z/2
