Answer:
The scale factor for the triangles (larger/smaller) = 6/2 = 3.
The area of the larger triangle equals the area of the smaller triangle times the square of the scale factor (32 = 9):
Area of Larger Triangle = Area of Smaller triangle * Scale Factor 2 = (3 cm2)*9 = 27 cm2.
Answer:
3
Step-by-step explanation:
Circumference = , where r is radius, and d is diameter
d=113/3.14=35.987, which is approximately 36
At 12 yards per hour, it will take 36/12=3 hours
Answer:
z = 70
x = 6
Step-by-step explanation:
Z and 70 are vertical angles so they are equal
z = 70
12x+38 and 70 are supplementary angles so they form a straight line
This means they add to 180 degrees
12x+38 + 70 = 180
Combine like terms
12x+108 = 180
Subtract 108 from each side
12x+108-108= 180-108
12x = 72
Divide each side by 12
12x/12 = 72/12
x = 6
Answer:
Factoring
Step-by-step explanation:
x^2 + 7x = x(x + 7) = 0
So
x = 0 or x = -7
