Step-by-step explanation:
m1.m2= -1
(4y = -2x -9)= (y = -1x/2 -9/4)
-1/2.m2= -1
m2 = 2
formula = y - y1 = m2 ( x - x1)
y - 10 = 2 ( x - (-7))
y - 10 = 2x + 14
y = 2x + 24
The longest length you can get with no extra is 56cm
Answer:
(3x - y)(3x + y)
Step-by-step explanation:
Both 9x^2 and y^2 are perfects squares.
The rule for factoring perfect squares is a^2 - b^2 = (a - b)(a + b).
Here, factoring (3x)^2 - y^2 results in (3x - y)(3x + y).
