Solve the equation and check the solution. 14-2n=-32
makvit [3.9K]

14 - 2n = -32

32 + 14 = 2n

46 = 2n

46/2 = n

23 = n


Checking:

14 - 2(23) = -32

14 - 46 = -32

-32 = -32 (Matched, answer is correct n = 23)

Find the area of a rectangle with a width of x3 + 5x - 9 and a length of x2 + 8.
Drupady [299]

Answer:

A = x⁵ + 13x³ - 9x² + 40x - 72  

Step-by-step explanation:

The formula for the area of a rectangle is length X width, or A = lw.

Substitute the equations for the sides into the formula:

A = lw

A = (x² + 8)(x³ + 5x - 9)      <= use the distributive property

A = x⁵ + 5x³ -9x² + 8x³ + 40x - 72   <= collect like terms

A = x⁵ + 13x³ - 9x² + 40x - 72
