Length=3width-5
(2(x))+(2(3x-5)=46
2x+6x+10=46
8x=56
x=7
width=7 length=16
Answer:
i think factor the expression (r+7)(r+14) is answer
Step-by-step explanation:
We have been that frequency (y) varies inversely with wavelength (x).
We know that two inversely proportional quantities are in form
, where a is inversely proportional to b and k is constant of variation.
Our required equation would be
.
To find frequency of blue light, we will substitute
and
in our equation as:


Therefore, the frequency of blue light is 764.
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>
