Answer:

x = 5

Step-by-step explanation:

y = x^2 - 3x - 10 = (x - 5)(x + 2) (x - 5)(x + 2) = 0 ==> x = -2 and x = 5.

Jina wanted to study how the area of a rectangle changes with the length if it’s width is fixed. She computed the areas of sever

olganol [36]

Answer:

The domain and the range of the function are, respectively:

$Dom\{f\} = [0\,m,5\,m]$

$Ran\{f\} = [0\,m^{2}, 10\,m^{2}]$

Step-by-step explanation:

Jina represented a function by a graphic approach, where the length, measured in meters, is the domain of the function, whereas the area, measured in square meters, is its range.

$Dom\{f\} = [0\,m,5\,m]$

$Ran\{f\} = [0\,m^{2}, 10\,m^{2}]$

Answer:

2100 square cm

Step-by-step explanation:

To find the AREA of a three-dimensional, non-circular figure, you would want to multiply length by width by height ( 20 x 7 x 15). Since we're just looking for area and not volume, this is the equation we'll be going with.

20 x 7 x 15 = 2100

Add in the units, and we get 2100 square cm.

Hope I could help.

- 5g = 20 How do you solve this

dezoksy [38]

Answer:

g= -4

Step-by-step explanation:

-5g = 20

Divide the -5 to both sides

-5g / -5 = 20/ -5

both -5 cancel out and g is left alone

20/-5 = -4

g= -4
