Answer:
4(x + 3)(2x − 7)
Step-by-step explanation:
4(x + 3)(2x − 7) = 4(2x² − 7x + 6x − 21)
= 4(2x² − x − 21)
= 8x² − 4x − 84

Answer:
30 31 33 are the three integer consective
Answer:
If y varies inversely as x, then we write it as:
y = k/x
where k is some constant.
If we multiply both sides of this equation by x we get an equation for k:
k = x*y
We are given that y=4 when x=7, therefore:
k = 7*4 = 28
Put this back into our original equation to get:
y = 28/x
If y = 0.75 when x = 0.5, set up a proportion -
0.75:0.5
x:3
Since you have to multiply 0.5 by 6 to get 3, multiply 0.75 by 6 to get your answer: y = 4.5 when x = 3.
