D , the answer is "six less than a number b"
(-2d^2+s)(5d^2-6s)
= (-2d^2*5d^2 + s*5d^2 -2d^2*-6s + s*-6s
= -10d^4 + 5sd^2 + 12sd^2 - 6s^2
=-10d^2 + 17sd^2 - 6s^2
This is the final result

hope this helps, i just took the quiz.
Answer:
Step-by-step explanation:
f(x)= 32(0.5)^x
f(5)= 32(0.5)^5
f(5) = 1
Let, first integer is x.
Therefore, other two are x+1 , x+2 .
Now, mathematical expression of given conditions is :
4x + 3 = 3(x+2)
4x + 3 = 3x + 6
x = 3.
So, the consecutive numbers are 3 , 4 and 5.
Therefore, the middle integer is 4.
Hence, this is the required solution.
