Answer:

Step-by-step explanation:
The equation of the given straight line is 2x - 3y + 15 = 0.
Now, we can express the equation as 3y = 2x + 15
⇒
..........(1)
The equation is in slope-intercept form and the slope is =
Therefore, the equation of a straight line which is perpendicular to (1) is
{Where c is any constant}
{Since, the product of slopes of two perpendicular straight lines is -1}
Now, putting c = 1, we get the equation as

Answer:
Area of trapezoid = 21 cm²
Step-by-step explanation:
Given:
Length of rectangular shape = 4 cm
Width of rectangular shape = 3 cm
Base of triangle = 3 cm
Number of triangle = 3 cm
Find:
Area of trapezoid
Computation:
Area of trapezoid = Area of middle rectangle + Number of triangle[Area of triangle]
Area of trapezoid = [l x b] + 2[(1/2)(b)(h)]
Area of trapezoid = [4 x 3] + 2[(1/2)(3)(3)]
Area of trapezoid = 12 + 9
Area of trapezoid = 21 cm²
Answer:

Step-by-step explanation:
x + y + y + z + z + x = 2x + 2y + 2z = 22
x + y + z = 22
22 ÷ 3 = 
The answer to your question is A. rational numbers.
Rational numbers are closed under any set of operations.
Integers are not closed under division because 1/2 is not an integer.
The set {-1, 0, 1} is also not closed under division because -1/5 does not fall in that set.
Whole numbers are not closed under division because 5/3 will produce a number that is not a whole integer.
Your answer is A. rational numbers.
Answer:
The greatest common factor of these two numbers is 3
Step-by-step explanation:
To find this, look for the highest number that both can be divide by to get whole numbers.
39/3 = 13
6/3 = 2
