Answer:
6
Step-by-step explanation:
6j + 27 = j + 57
6j - j = 57 - 27
5j = 30
j = 30 / 5
j = 6
Answer:
y =
+ 2
Step-by-step explanation:
The slope of the line that has an x intercept of (2,0) and y-intercept of (0,-6) is:
Slope(s) = Change in y ÷ change in x
s =
= 3
The slope of the perpendicular line to this line with slope of 3 has to have a slope of -1 ÷ 3 = 
Reason: The product of slopes of lines perpendicular to each other have to be -1
So the slope of the perpendicular line that passes through (-6,4) is 
As mentioned earlier, we derive a slope of a line by dividing the change in y by the change in x
Taking another point (x,y) on the line,
= 
= 
y - 4 =
x - 2
y =
x + 2
Perimeter is , or around 63.89 in.
If you meant that the area was 225 in²:
Perimeter is 60 in
Answer:
2xy+10z-5yz-4x
Step-by-step explanation:
Just put the positives and negatives together. You can't add or subtract any of them because they aren't like terms.
