Answer:
The first one is missing (d - 9) so it would be 5(d -9) or when you factor it out 5d - 45
In the second one (d + 7) is missing so it will be 8d(d + 7) so if you factor that out you will receive 8d^2 + 56
Step-by-step explanation:
3d^2 + 18d -21 =(3d -3)( d + 7)
3d^2 -30d +27 =(3d -3)(d - 9)
Answer:
no solution I believe
Step-by-step explanation:
b/c x and y cancel out so it cant be solved
The equation for density is:
To help you remember - my teacher told us to remember "We <span>♡ density," and the heart stands for </span>
, or
. Cheesy, but it works!<span>
</span>
Back to the problem:We know the mass if 49g and the volume is 7
, so plug these values into the equation for density:
Answer: The density is 7 g/
