1/4 # hamburger = 16 oz to a pound so 1/4 is 4 oz.
1 doz baseballs (12), 5 oz each
Box = 9 oz.
Total weight = 12x5 = 60 oz. + 9 oz. = 69 oz.
69/16 = 4 lb. 5 oz.
Answer:
Step-by-step explanation:
This is more easily understood if you take out a common factor of -1
-1(x^2 + 15x + 56)
7*8 = 56
7 + 8 = 56
-1 (x +8)(x+7)
We are given two binomials: x+4 , x^2-9.
x+4 can't be factored. Therefore, it is a prime.
Let us work on x^2-9.
9 could be written as 3^2.
Therefore, x^2-9 = x^2 - 3^2.
Now, we can apply difference of the squares formula to factor it.
We know a^2 -b^2 = (a-b) (a+b).
Therefore, x^2 - 3^2 can be factored as (x-3) (x+3).
So, x^2-9 is not a prime binomial because it can be factored as (x-3) (x+3).
It’s ether 138.6 or 101.4. 123 rounded to the nearest tenth is 120 so you ether add or subtract
