Answer:

Step-by-step explanation:
We are given zeros as x=-4, x=-2
so, we can set up function as

Vertex is at (-1,3)
It means that graph passes through point (-1,3)
so, we can plug x=-1 and f(x)=3
and then we can solve for 'a'

we get

now, we can plug it back
and we get

now, we can simplify it

Answer:
Each golf ball costs about <u>$2</u>.
Step-by-step explanation:
Given:
Donald bought a box of golf balls for $9.27. There were 18 golf balls in the box.
Rename the decimal dividend as a whole number that is compatible with the divisor to estimate the quotient.
Now, to find the cost of each golf ball.
<u>As given:</u>
<em>Rename the decimal dividend as a whole number that is compatible with the divisor to estimate the quotient.</em>
As, the cost of golf ball box = $9.27.
So, 9.27 nearest to whole number is 9.
Thus to get the cost of each ball:
18 golf balls cost = $9.
So, 1 golf ball cost = 
Therefore, each golf ball costs about $2.
Answer:
The answer is B
Step-by-step explanation:
Each smaller rectangle is being multiplied by <em>a </em>so 2a + 3a + 4a would give you the total area of the entire large rectangle.
Answer: 154: 200 145: 100
Step-by-step explanation:
If the number next to the place value is 5 or more you round it up. Like I did 154. But if the number is less that 5 you put everything to zero EXCEPT for the place value you are rounding. Good Luck
