1/2 *(a+b)-(a-b)²
a=18, b=14
1/2 *(18+14)-(18-14)²=1/2 *(18+14)-(18-14)²= 1/2*32-4²=16-16=0
answer D
answer B
2 factors have 2 terms: (x+4) and (y+4)
Domain:
We know that
domain is all possible values of x at which y is defined
so, all given x-values in this table is domain
so, domain is {-2, -1, 0, 1, 2, 3}...........Answer
Range:
We know that
range is all possible values of y at which x is defined
so, all given y-values in this table is range
so, range is {-3, -1, 1, 3,5, 7}...........Answer
Step-by-step explanation:
Since x² + 3x - 4 = (x + 4)(x - 1), the correct answer is D.
X=5
90°-50°=40°
5x+15=40°
5x=25°
x=5
We calculate 40% from 369,00 $, this is discount
40%*369=
After sale coat costs 147,60 less so:
369 -147,60=221,40 $
Now I will pay for the coat 221,40$.
