Answer:
-122
Step-by-step explanation:
f(5)= 5- 8×5² + 13×5 +8
= 5 - 200+ 65+8
=78 -200
= -122
Answer:
13 cases
Step-by-step explanation:
we know that
You have 1 case of soap bars
There are 150 bars in a case
You use 300 bars of soap per day ----> 2 cases per day
using proportion
Find how many cases do you need to order to have enough for 7 days
Let
x ----->the number of cases
2/1=x/7
x=2*7=14 cases
but remember that you have 1 case
so
you needed 14-1=13 cases
Answer:
B) 28x + 9
Step-by-step explanation:
The definition of the perimeter of a closed figure is the total distance around the edge of an enclosed figure.
You can obtain the perimeter of polygons by simply adding up all of the sides of the polygon.
Since all of the sides values are given to you, you can write the expression:
6x + 1 + 5x - 3 + 6x + 1 + 11x + 10 in order to represent the perimeter.
This equals to 28x + 9
Answer: put 3 in the blank
Explanation:
The last row shows that this equation will never be true no matter what value of x. This shows that setting the coefficient of x to 3 makes the equation have no solutions.
