Answer:
150
Step-by-step explanation:
15*10
Lets get rid of the 0 for now
15*1
That is 15 added to itself 0 times so it is 15
Now lets put the 0 back
and we will get
150
Moving to the right and up, the only two points that could be placed in another point would be C or B
The answer would be 6. point C could be the image of E
Answer: C. (x-3)(x+3)
Step-by-step explanation: Since both terms are perfect squares, factor using the difference of squares formula a^2-b^2=(a+b)(a-b) where a=x and b=3.
Hope this helps you out! ☺
Answer:
Step-by-step explanation:
strategy: find the distance of the two points, take half of that, b/c that will be the radius, Then use the area of a circle formula to find the answer
P1 = (1,-1) in the form (x1,y1)
P2= ((3,3) in the form (x2,y2)
dist = sqrt [ (x2-x1)^2 + (y2-y1)^2 ]
dist = sqrt [ 3 -1 )^2 + 3-(-1)^2 ]
dist = sqrt [ 2^2 + 4^2 ]
dist = sqrt [ 4 + 16 ]
dist = sqrt [20]
r = /2
area of circle =
area of circle = ( /2)^2
area of circle = ( /2)( /2)
area of circle = (20 / 4)
area of circle = 5
area of circle = 5
9x^2 -c =d
add c to each side
9x^2 = c+d
divide by 9
x^2=(c+d)/9
take the square root on each side
x = +- sqrt ((c+d)/9)
simplify
x = +- 1/3 sqrt (c+d)
Answer: 1/3 sqrt (c+d), - 1/3 sqrt (c+d)
