1 + 1/1 or 9/9
Or if you have to make the 1 to a 2 then 1/.5
I think the greatest number of students that can be in each row is 18.
you start by finding the highest common factor of 90 and 72
so it means that the teacher will end up with 5 rows of boys and 4 rows of girls with 18 students in each row.
Answer: The cost of renting the car for one day and driving at 75 miles = $ 47.5 .
Step-by-step explanation:
GIven: Daily cost of renting car = $ 25.00 + $0.30 per mile driven
Let x = Total distance traveled ( in miles).
Then total cost of renting (in $)= 25+0.30x
For x= 75 miles
The total cost of renting (in $)= 25+0.30(75)
=25+22.5
= $47.5
Hence, the cost of renting the car for one day and driving at 75 miles = $ 47.5
Answer:5
Explaining:
10% of 50
= 10%=10/100 = 0.1
= 0.1 (x) times 50
= 5
In order to factorate the trinomial, let's first find its roots using the quadratic formula:
![\begin{gathered} b^2-4ac=12^2-4\cdot4\cdot9=144-144=0 \\ x_1=x_2=\frac{-b\pm\sqrt[]{b^2-4ac}}{2a}=\frac{-12+0}{2\cdot4}=-\frac{12}{8}=-\frac{3}{2} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20b%5E2-4ac%3D12%5E2-4%5Ccdot4%5Ccdot9%3D144-144%3D0%20%5C%5C%20x_1%3Dx_2%3D%5Cfrac%7B-b%5Cpm%5Csqrt%5B%5D%7Bb%5E2-4ac%7D%7D%7B2a%7D%3D%5Cfrac%7B-12%2B0%7D%7B2%5Ccdot4%7D%3D-%5Cfrac%7B12%7D%7B8%7D%3D-%5Cfrac%7B3%7D%7B2%7D%20%5Cend%7Bgathered%7D)
Now we can write the trinomial in the form:

So we have that:

So 2x + 3 is a factor of the trinomial, therefore the answer is D.
