Step-by-step explanation:
3x + (2x + 4) is equivalent to (3x + 2x) + 4
because there is no change of signs taking place as there is no (-) sign in front of the brackets
3x + (2x + 4) | (3x + 2x) + 4
3x + 2x + 4 | 3x + 2x +4
5x + 4 | 5x + 4
The greatest common factor of 64 and 96 is 32, so, the first step after finding the great common factor is convert and rewrite "64 + 96" into distributive property.
You should get 32(2 + 3)
Answer:
yes
Step-by-step explanation:
If 2 lines are perpendicular then the product of their slopes = - 1
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - x - 4 ← is in slope- intercept form
with slope m = - 1
5x - 5y = 20 ( subtract 5x from both sides )
- 5y = - 5x + 20 ( divide all terms by - 5 )
y = x - 4 ← in slope- intercept form
with slope m = 1
Thus product of their slopes is - 1 × 1 = - 1
Therefore the lines are perpendicular
