Answer:
HOPE THIS HELPS!!
Step-by-step explanation:
YOU could find it by doing these steps:
Atual Area = ���� square units.
Scale Drawing Area = �� square units.
Value of the Ratio of the Scale Drawing Area to the Actual Area:
Answer:
x = -8 or x = 3
Step-by-step explanation:
To factor ax² + bx + c, use AC method.
a times c is 1 × -24 = -24.
Factors of ac (-24) that add up to b (5) are 8 and -3.
Divide by a and reduce: 8/1 and -3/1.
Therefore, the factors are x + 8 and x − 3.
x² + 5x − 24 = 0
(x + 8) (x − 3) = 0
x = -8 or 3
We know in these kind of triangles that have a 90 degrees angle, we can do:

so the first question:

and then:

so , when you want to rationalize , usually you must multiply the irrational factor as 1:

so , now multiply:

in the next question,we know negative numbers in radical don't have any solution so 2 is correct,
Answer:


Step-by-step explanation:
because 8(8)=64 and 8 is the positive square root of 64.
because 17i(17i)=289i^2=-289(-1)=-289.
