Answer:
3x^2+14x-5
Step-by-step explanation:
Use the foil method. Multiply 3x by (x+5) first, then multiply -1(x+5). This produces 3x^2+15x-x-5, reduce to get 3x^2+14x-5.
Answer:
A.
mean=82.286
Rounded to the tenths place would be= 82.3
Step-by-step explanation:
The Mean is found by adding all of the values together
Then dividing it by how many values there are.
In this instance, all the values added up equal 576
576 now will be divided by how many temperatures are recorded.
576/7=82.286
82.286 Rounded to nearest tenth=82.3
-2. All you’re doing is going from the number you start with and performing the opperations in the order they appear (-4+3-2+6-5=-2)
Answer:
A) (x +2)(x -3)² = 0
Step-by-step explanation:
Synthetic division by (x-3) gives the quadratic x² -x -6, which has factors (x -3) and (x +2). This is confirmed by another round of synthetic division.
The resulting factorization is ...
... (x +2)(x -3)² = 0
_____
A graph confirms a double zero at x=3 and one at x=-2.
51 is the highest multiple you can take from 53
One way to find this out is take 53-30 and you get 23 from this you know 21 is the highest multiple you can get so 30+21 = 51
51/3 is 17 so each student gets 17 blocks and the thus remainder is 2
Another way is to divide 30 and 21 by 3 and add them both together and you will get the same answer
Do always make the numbers easier to solve and save time scrambling..
