Given with the function of x which is f(x)=15x² + 360, we are tasked to solve for the value of x. The solution was discussed and shown below:
Set x=0, then we have:
0=15x² + 360
Transpose 360
15x²= -360
Divide by 15
x²= -360/15
x²= - 24
x = sqrt 4*6i
Therefore, the answer is letter B.
Let
x--------> <span>represents the length of a single tile
L-------> t</span><span>he length of the floor
W------> the</span><span> width of the floor
A--------> </span>area of a tiled kitchen floor
<span>
we know that
A=W*L
A=</span>4x²<span> + 24x + 27
</span>so
W*L=4x² + 24x + 27---------> equation 1
L=2x+9------> equation 2
substitute equation 2 in equation 1
W*[2x+9]=4x² + 24x + 27
W=[4x² + 24x + 27]/[2x+9]
therefore
the answer is
the <span>expression that represents the width of the kitchen in terms of x is
</span>W=[4x² + 24x + 27]/[2x+9]
87 is the mean.
To find the mean, you must
- add all of the numbers
- divide by the amount of numbers given
In this case, you would want to do (86 + 80 + 95)/3. This would give you an answer of 87.
Answer
Step-by-step explanation:
your answer would be C.13
because 13x2=26 then 26-39=13
Hope this Helps you out!!!! ^-^
They can make 4 teams and have 4 players that won’t be in a team.
This is because 5*5 is 25 but they don’t have 25 players so you would have to go down which is 4*5=20. Sorry if that’s very confusing but hope that helps!
