Answer:
8
Step-by-step explanation:
I think it is 8 because I did the equation Q3=3/4(12) and I got 9 which means the answer is 8 which is the 9th number
For every 3 green grapes there are 4 black grapes.
There are 24 green grapes, which is 3*8, so there must be 4 * 8 = 32 black grapes.
S=2(4x+2x)+4x^2=4x^2+12x
4x^2+12x=7
4x^2+12x-7=0
D=12^2-4x4x(-7)=256
X1=(-12-16)/(2x4)=-3.5 impossible
X2=(-12+16)/(2x4)=0.5
A
Answer:
x=2
Step-by-step explanation:
6(x-6)+2x=6(2-3x)+4x-2x
6x-36+2x=12-18x+4x-2x
8x-36=-16x+12
24x-36=12
24x=48
x=2
The are of a square is determined by squaring the side. And the length will hence, be determined by square rooting the area.
∴ length of this square is = √84 = 9.165
