Answer:

The answer to all of those questions would be x=-1.8

Step-by-step explanation:

7x(x + 1.8) = 0 - Distribute through the Parenthesis -

7x^2 + 12.6x = 0

x(7x + 12.6) = 0

x = 0

7x + 12.6 = 0

7x = -12.6

x = -12.6/7

x = -1.8

so x = 0 or x = -1.8

The area of a rectangle is 10r (squared) − 11r − 6. The width is 2r − 3. What is the length?

sladkih [1.3K]

10r^2 − 11r − 6 = (2r - 3)(5r +2)
so
A = (2r - 3)(5r +2)
as you know A = L * W
if width = (2r - 3) then length = (5r +2)

answer
length = (5r +2)
