Answer:
Step-by-step explanation:
x= -5 or x=2
that's what i think it is.
I’m pretty sure it’s -6 because f(x) is the first curve and g(x) is the second and there’s six spaces between each of their vertexes
3000x1.12
=3360
Therefore, Frankie will have £3360 percent chance for at the end if the time period
2040 = n/2(20+(n-1)4)
4080 = n(20+4n-4)
4080= 20n +4n^2 -4n
1020 = 4n + n^2
n^2 +4n -1020 =0
use common formula (can't write out so just look at answers. sorry)
which gives answers of n=-34 and n=30. since n can only be positive, n=30 so there are 30 rows. I liked that challenge
A = x * x = x^2
B = 6 * x = 6x
C = 8 * x = 8x
D = 6 * 8 = 48
So the area of the whole shape is each side added up then multiplied to give (x+6)(x+8) =
x^2 + 14x + 48
