Answer:
A=4.
Step-by-step explanation:
Note: In the expression of area the first term should be 
.
It is given that area of a rectangular floor of your house is 
and the length is 
units.
We know that, area of a rectangle is
Since length of the rectangle is , therefore is a factor of and the value of is 0 at x=-2.
Divide both sides by 4.
Therefore, the value of A is 4.
Answer: Ix - 950°C I ≤ 250°.
Step-by-step explanation:
Ok, the limits are:
700°C to 1200°C.
The first step is to find the mean these numbers:
M = (700°C + 1200°C)/2 = 950°C
Now let's find the distance between the mean and the limits (which is equal to half the difference between our numbers)
D = (1200°C - 700°C)/2 = 250°C.
Now we can write our relation as:
Ix - MI ≤ D
Ix - 950°C I ≤ 250°.
if x = 1200°C.
I1200°C - 950°CI = 250°C ≤ 250°C ---- true.
if x = 700°C
I700°C - 950°CI = I-250°CI = 250°C ≤ 250°C ---- true
Answer:
The percent values were written incorrectly in the equation.
The amount of 7% solution should be written as 1 – x, not x – 1.
