Answer:
-2n + 6
Step-by-step explanation:
When we simplify the equation, we add like terms. 5n - 7n is 2n and 6 doesn't have anything to add/subtract to, so we have -2n + 6
The answer would be B. 48cm squared(2)
To solve: You need to figure out the area of the two parts by finding the area of each figure separately, so what I would do is make a imaginary line for the line to the left of the 6, after you do that you will have two different figures, then you do 6×2 to find the area of the first figure, then do 9×4 to find the are of the second figure.....that would give you 12 and 36. You then add both 12 and 36 together to get the awnser of 48cm squared....if you need more help I would be morw then happy to do so. Just message me back
To find the x int, sub in 0 for y and solve for x
3x - 9y = 10.8
3x - 9(0) = 10.8
3x = 10.8
x = 10.8/3
x = 3.6 or (3.6,0) <== ur x int
to find the y int, sub in 0 for x and solve for y
3x - 9y = 10.8
3(0) - 9y = 10.8
-9y = 10.8
y = -10.8/9
y = - 1.2 or (0,-1.2) <== ur y int
I hope this helps you
if B midpoint for AC than AB=BC=a
AB/AC=BF/CE
a/a+a =BF/90
a/2a=BF/90
1/2=BF/90
BF=90/2
BF=45
- 3x + 2 ( - 6x² + 13x - 6 )
= - 3x - 12x² + 26x - 12
= - 12x² + 23x - 12
