21g=84
g=84/21
g=4
The answer is B
Let "a" and "b" be the two numbers
So a*b=-8 and a+b=-7
Therefore S=-7 and P=-8
Using (x^2)-S+P=0 => (x^2)-(-7)+(-8)=0 => (x^2)+7-8=0
By factorizing we get (x+8)(x-1)=0
So a can be either -8 or 1 and b can be 1 or -8
Meaning that the two numbers are -8 and 1.
Answer:
63 feet.
Step-by-step explanation:
The total diameter of the circular garden is given by 5ft+ 10 ft + 5 ft= 20 feet
As the circumference of the circle = 2πr where r = radius obtained by dividing the diameter by 2. Here the diameter = 20 feet and r= d/2 = 20/2 = 10 feet
Putting the values in the circumference formula
Then C= 2(22/7) (10)= 62.85 feet
Rounding gives almost 63 feet .
Answer is b . G)f(x))=9x^3+30x
I think that (1/4)x+8 would be your algebraic expression.
