Answer:
The GCF (HCF) of the numerical factors −12,−6,−4,−3,−2,−1,9,9,18,18,36,36 - 12 , - 6 , - 4 , - 3 , - 2 , - 1 , 9 , 9 , 18 , 18 , 36 , 36 is 12 .
Step-by-step explanation:
For 13. just add all the sides.
4 + 21 + 23 + 7 + 9 = 64
For 14. multiply width and height of both shapes then add them together.
1.7 x 5.2 = 3.74 ( rectangle area )
3.0 x 3.0 divided by 2 = 4.5 ( triangle area )
Add the two answers
3.74 + 4.5 = 8.24
Answer:
Step-by-step explanation:
y=2(x-8)(x+2)
The x intercepts occur when y=0, so when x=8 and -2
The vertex is where the equation is at a minimum/maximum in this case (x,y)=(3,-50)
The axis of symmetry occurs between the two roots, 8 and -2 which x=3
The y intercept is the value of y when x=0, in this case (0, -32)
Answer:
The area of the shaded region= 37.68
Step-by-step explanation:
Area of the outer circle= 2* 3.14* 36 (Area of the circle=2
r)
=113.04
Area of the inner circle=2*3.14* 12
=75.36
Area of the shaded region= Area of the outer circle- Area of the inner circle
= 113.04- 75.36
=37.68
Just 82 because in order for the number to be 83 it would have to be a 5 after the decimal (82.575= 83). Anything lower than a 5 after the decimal (82.375), would be 82. I hope this helps!
