Answer:
x = A/7
Step-by-step explanation:
Given that the screen is rectangular, recall that the area A of a rectangle whose length is L and width is W is given as
A = L * W
Hence if the width is 7 inches and the length is x inches then the area which is A square inches is connected to both sides as
A = x * 7
Divide both sides by 7
x = A/7 inches
Answer:
3.85 % to 2 decimal places
Step-by-step explanation:
If you have Rs5 profit it means that you have sold it for 135

Step-by-step explanation:
FOIL
First
Outer

Last
This is the theorem that I use, so to expand, you multiply the first number in the equation so it would be w times w because in (w-9) and (w+3) w is the first term. So now you do the outer number which is the first and last number in the equation which is w and 3 and we multiply them together. now we do the inner, which are the two inner terms, which are -9 and w and we multiply them. Now we do the last terms in each ( ) which is -9 and 3 and we multiply them. This is kinda hard to get used to, but it helps so much when you are trying to expand trinomials that are multiplied together!
so we add all the answers we got for first, outer, inner and last numbers
w*w+w*3+-9*w+-9*3
w2+3w-9w-27
w2-6w-27
Hope that helps :)
Answer:
268.08
Step-by-step explanation:
V=4/3πr² (r=4)
V=4/3π(4)r² = 268.08
