9+3 =12
12/4 = 3
(3)2-4(3)-3
6-12-3
-9 is the answer
Area = 1/2 x base x height
Let the height be x.
Height = x
Base = 2x
Area of triangle = 1/2 x base x heght
Plug base and height into the variables:
(1/2)(2x)(x) = 196
Combine like terms:
x² = 196
Square root both sides:
x = 14
Find Base and height:
Base = x = 14 km
Height = 2x = 2(14) = 28 km
Answer: Height = 28km
7/10 is 7 pieces of the whole. The whole would be cut into 10 pieces and you have 7 of the 10...7/10.
The answer is f=12.56 because you take 7*3.14 and get 21.98 and then you take 3*3.14 and get 9.42 then you take 21.98-9.42 and get 12.56
