2n2 i’m gonna assume is 2n^2
and n2 is 2n
2n^2-10n+5
The correct answer is f(x)=-5+0.5x
Looking at the data, we can see that the data increases at a constant rate. We can find this rate, the slope, using the formula
m=(y₂-y₁)/(x₂-x₁)
Using the first two ordered pairs, we have
m=(1-0.5)/(12-11) = 0.5/1 = 0.5
Writing this in point-slope form, y-y₁=m(x-x₁), we have
y-0.5=0.5(x-11)
Using the distributive property, we have
y-0.5=0.5x-0.5*11
y-0.5=0.5x-5.5
Adding 0.5 to both sides,
y-0.5+0.5=0.5x-5.5+0.5
y=0.5x-5
Answer:
3x^2 +14x-5
Step-by-step explanation:
(3x-1)(x+5)
We need to FOIL
first 3x*x =3x^2
outer 3x*5 = 15x
inner -1*x = -x
last -1*5 =-5
Add it together
3x^2 +15x-x-5
Combine like terms
3x^2 +14x-5
Answer: (x+1)(x+2)
step by step explanation:
Answer:
350 sq ft
Step-by-step explanation:
Given that:
840 sq ft area has a bedroom, kitchen and bathroom.
Let the area of bedroom be sq ft.
Then the area of kitchen will also be sq ft.
Let the area of bathroom be sq ft.
As per question statement:
Tiles ordered to cover two kitchens and two bathrooms is 980 sq ft.
i.e.
Subtracting equation (1) from (2):
i.e. (2) - (1):
sq ft
Putting the value of in (1):
Therefore, the carpet needed for each bedroom = <em>350 sq ft</em>
