Answer:
39
Step-by-step explanation:
x-3y=9
x-y=29
subtract
-2y=-20
y=10
x-10=29
x=39
Negative x axis
Since , the value of x comes out to be -2and -4 .
;))))
It’s a. vertex is the lowest or highest point so (1,-8) x-intercepts is where the parabola hits the x axis so (-1,0) and (3,0)
Square Perimetre = Side x 4
So a length of a square ground is 160/4 = 40 (m)
It would be the letter A.
I hope this helps! <3
