Step-by-step explanation:
The figure transformation is a dilation. And the side lengths increased by two.
Answer:
Step-by-step explanation:
salut :
en utilisant le theorem de Pythagore on obtient :
AC²= AB² + BC²
(a+5)² = 7²+a²
a²+10a+25 = 49+a²
10a+25 =49
10a =24
donc : a = 24/10 = 12/5 = 2.4 unit
<u>Solution-</u>
The equation given here,







But, at x=1,
becomes infinity so it can't be a solution to the equation.
∴ x=1 is the extraneous solution of the equation
Hello :
a = w l
l = a/w
l =( 6x²y+4y²x)/(2xy)
l = 2xy(3x+2y) /(2xy)
l = 3x+2y
Answer:
B
Step-by-step explanation:
The vertex of the parabola is (-1,-4)
So the axis of symetry is x=-1
