Answer:
-74.069, -74.69, 74.59, 74.6
Step-by-step explanation:
negative numbers are smaller than positives
Little tip ** if u r going from a larger shape to a smaller shape, the scale factor is going to be a proper fraction....a number less then 1 but greater then 0
BC = 66......EF = 11.......66 times what is 11
66x = 11
x = 11/66 reduces to 1/6
so 66 * 1/6 = 11
now compare the other sides...
42 * 1/6 = 7.......looks like AC and DF
72 * 1/6 = 12...looks like Ab and DE
so ur multiplying every number in the big triangle by 1/6 , and getting the measures of the little triangle....so ur scale factor is 1/6 <==
A. x=3/2
D. x=1/2
Solve for x over the real numbers:
4 x^2 - 8 x + 3 = 0
The left hand side factors into a product with two terms:
(2 x - 3) (2 x - 1) = 0
Split into two equations:
2 x - 3 = 0 or 2 x - 1 = 0
Add 3 to both sides:
2 x = 3 or 2 x - 1 = 0
Divide both sides by 2:
x = 3/2 or 2 x - 1 = 0
Add 1 to both sides:
x = 3/2 or 2 x = 1
Divide both sides by 2:
Answer: x = 3/2 or x = 1/2
