Answer: -3x²-9x+84
Step-by-step explanation:
Let the zeros be r1 and R2
The equation of a parabola going through those two zeros is
y=a(x−r1)(x−r2)
Answer:
X/15 = 32/20
x = 24 ft
Step-by-step explanation:
X/15 = 32/20
x = 24 ft
Answer:
13
Step-by-step explanation:
4+(-3)-2*(-6)
Let us start from the left
2*(-6)= 2 times 6 , where we will have a negative sign on the result as + when multiplied by - gives - (negative)
2*(-6)=-12
4+(-3)-2*(-6) = 4+(-3)-(-12)
Now we open the bracket from the left. It the sign outside the bracket is negative the sign in the bracket will be changed
Hence
4+(-3)-(-12)= 4-3+12
Now -3 +12 we find the difference as the signs are opposite and then place the sign with the larger number
Hence -3+12=9
4-3+12=4+9 = 13
