Its true because integers are negative and positive numbers including zero, and a whole number is a positive counting number including zero
Answer:
A
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 6, thus
sum = 180° × 4 = 720°
Thus each interior angle = 720° ÷ 6 = 120° and therefore
3x = 120 ( divide both sides by 3 )
x = 40 → A
Answer:
Question 9 = 5.5 hours (Cross multiplication)
Answer:
The area of the yard is;
5x^4 -2x^3+9x^2+50
Step-by-step explanation:
Here, we want to calculate the area of the yard
Mathematically, this can be calculated as the difference between the area of the plot and the base area of the house
So, we simply proceed to calculate a subtraction here;
Thus, we have this as;
5x^4 + 9x^2-4x -(2x^3-4x-50)
= 5x^4 + 9x^2-2x^3+ 50
Rearranging this, we have;
5x^4 -2x^3+9x^2+50
