The number is 63, so the quotient is 2.
Two digit numbers divisible by 21:
21, 42, 63, 84
21: 2-1 = 1 * 3.5 = 3.5
3.5*2*1 = 7 but 7 does not equal 21
42: 4-2 = 2 * 3.5 = 7
3.5*4*2 = 28 does not equal 42
63: 6-3 = 3*3.5 = 13.5
3.5*6*3 = 63 :)
Check:
21(6-3)=21(3)= 63 :)
3.5(6)(3) = 21(3) = 63 :)
63: 6/3 = 2
For this case, what you must do is add the area of each of the triangles to find the total area of the polygon.
We have then:
A = 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2
A = 16
Equivalently, as the area of each triangle is the same, then:
A = 2 * (8)
A = 16
Answer:
the area of the polygon is:
16
Option 3
Answer:
The average rate of change between -1 and 2 is 1.
Step-by-step explanation:
To get this, use the two ordered pairs (-1, 5) and (2, 8). Now use the slope formula to find the rate of change.
m(slope) = (y2 - y1)/(x2 - x1)
m = (8 - 5)/(2 - -1)
m = 3/3
m = 1
Answer:
A traingle cannot be right angled and obtuse angled at the same time. Since a right angled triangle has one right angle the other two angles are acute.
