Answer:
-8, -7
Step-by-step explanation:
f(x)=x^2+15x+56
0 =x^2+15x+56
What two numbers multiply together to make 56 and add together to 15
7*8 = 56
7+8=15
0 = (x+8) (x+7)
Then use the zero product property
x+8 =0 x+7 =0
x+8-8 =0-8 x+7-7 =0-7
x=-8 x=-7
Answer:
7 21 35 49
3 9 18 27
Step-by-step explanation:
the top is going up by 14 and you subtract 9 from 27
Do $8.31/3 and $12.95/5 and that will give you a price per pound and whichever is cheaper would be a better deal.
The answer is
h= -41.36
You first multiply -8.1(-0.4) and you get 3.24.
Then you subtract 3.24 - 44.6 to get h.
