Answer
N-9=-18
Move the -9 to -18 and add those cuz if there’s two negative u have to add
Add 9
For x²+bx+c, to complete the square, you add (half of b)²
b=8 in this case, so you add 4², which is 16
x²+8x+16-16-4
y=(x+4)²-20 is the final form.
7x-35<2x-10 distribut it
7x-2x<-10+35 collect like them
5x<25 divide both side by 5
x<5
-DIVIDE- the area of a triangle by the -BASE-
, and -MULTIPLY- the result by -2-
Explanation:
Thats because the formula for the area of a triangle is 1/2 x base x height OR (much not confusing formula) BASE x HEIGHT divided by 2
