Answer:
Fourth option.
Sixth option.
Step-by-step explanation:
We know that:
- Any number you can find on the number line, is a Real number.
- Integers contains positive numbers, negative numbers and zero. Every Integer is a Rational number.
- A Rational number is that number that can be written in the following form:
Where "a" and "b" are integers ().
- An Irrational number cannot be written as a simple fraction.
- A Whole number is any of the numbers {}. Every Whole number is a Rational number.
- Natural numbers contain the set of positive integers{} or to the set of nonnegative integers {}, Every Natural number is a Rational number.
Based on this, since is in the form where and , it is a Rational Number and therefore a Real number.
Lin: 7x+14=91, 91-14=7x, 77=7x, divide each side by 7, x=11
noah: x+2=91/7, x+2=13, subtract 2 from both sides, x=11
Answer:
123.5 m^2
Step-by-step explanation:
The area of the whole rectangle is 9 x 19 = 171 m^2
The area of the region that isn't shaded is (5 x 19)/2 = 47.5 m^2 because the height of the triangle is 5 (9 - 4) and the area of a triangle is
(height x length)/2
171 - 47.5 = 123.5 m^2
