Given
A frame is 9in wide and 6 in tall.
If it reduces to a width of 3 in
Find out the how tall will it be .
To proof
As given in the question
A frame is 9in wide and 6 in tall.
reduces to a width of 3 in
now as shown in the table given below
This table shows that the width of a frame is directly proportional to the height (tall) of the frame.
let us assume that the height of the frame after reduces width to 3in be = x
than the equation becomes
put the all the value
we get
solve the above
x = 2in
therefore 2in tall will be the frame .
Hence proved
Answer:
C. 0 ≤ X ≤ 40
Step-by-step explanation:
The equation is valid for positive values of x not greater than 40.
_____
Personally, I might put the domain at 1 ≤ x ≤ 40, because there's no point in using the equation (or parking the bus) if zero people are going on the trip.
Answer:
6x5x5
Step-by-step explanation:
the square is a 5x5
and there are 6 of those squares
so it is 6x5x5
We need to express this statement into a equation:
First of all. We will walk through the statement step by step into a mathematical language, so:
1. The sum of five and x:
x + 5
2. Twice the sum of five and x:
2(x + 5)
3. Eight less than x:
(x-8)
Finally the whole statement is:
4. <span>Twice the sum of five and x is eight less than x:
</span>
2(x + 5) = (x-8)
2x + 10 = x - 8
x = -18
2x^2+(6-1)x-3
2x^2+6x-x-3
2x(x+3)-1(x+3)
(2x-1)(x-1)
