Answer:
12×11×10×9×8×7= 665 280 ways
___________________
Step-by-step explanation:
The first inquiry has 12 ways
The 2nd inquiry has 11 ways
The 3rd inquiry has 10 ways
The 4th inquiry has 9 ways
The 5th inquiry has 8 ways
The 6th inquiry has 7 ways
Answer:
Since we know that ABCD ~ EFGH, we have the ratios:
EF/AB = GH/CD
=> 0.4/1.2 = x/1.8
=> x = (1.8 . 0.4)/1.2 = 0.6
So x = 0.6
Answer:
octagon, because 4 + 4 = eight sides, and octagons have 8 sides
Step-by-step explanation:
Hope that helps!
The easiest way is to try the point (-4,1), that is, x=-4, y=1,
to see which equation works.
b works.
The usual way to do it is to find the equation of the circle
standard form of a circle is (x-h)²+(y-k)²=r², (h,k) are the coordinates of the center, r is the radius.
in this case, the center is (-2,1), so (x+2)²+(y-1)²=r²
the given point (-4,1) is for you to find r: (-4+2)²+(1-1)²=r², r=2
so the equation is (x+2)²+(y-1)²=2²
expand it: x²+4x+4+y²-2y+1=4
x²+y²+4x-2y+1=0, which is answer b.
Answer: 9
Step-by-step explanation:
s = 7
k = 4
x = 6
7 - 4 + 6
3 + 6
9
