The points (1,-2) and (4,16) are not in the line but the point (-3,-18) is on the line. (Work is shown in the image)
1. The area of the full rectangle is 21 * 28 = 588. We will need this later.
Like you drew, there is an imaginary triangle missing. We can find the dimensions of it by subtracting from the given information. The shorter leg of it is 21 - 12 = 9, the longer leg is 28 - 14 = 14.
Now we find the area of the triangle. Area of a triangle is 1/2 * base * height. So 1/2 * 9 * 14 = 1/2 * 126 = 63.
Now we do the full area of 588 minus the area of the missing triangle piece.
588 - 63 = 525 ft²
2. Do the area of the rectangle and then this time add on the area of the triangle. 7 * 15 = 105. Area of the triangle = 1/2 * 2 * 7 = 1/2 * 14 = 7.
105 + 7 = 112 in²
Answer:
3.50x= t
Step-by-step explanation:
x square feet of teh floor
t= total cost
You use the Pythagorean theorem which is a^2+b^2=c^2
So....
.8^2+.6^2=c^2
.64+.36=c^2
1=c^2
1=c becaaue the square root of one is one
Option D: 
; all real numbers.
Explanation:
Given that the functions are 
and 
We need to determine the value of 
and its domain.
<u>The value of </u><u>:</u>
The value of can be determined by multiplying the two functions.
Thus, we have,
Thus, the value of is
<u>Domain:</u>
We need to determine the domain of the function
The domain of the function is the set of all independent x - values for which the function is real and well defined.
Thus, the function has no undefined constraints, the function is well defined for all real numbers.
Hence, Option D is the correct answer.
