Answer:
Step-by-step explanation:
Height doubles at every 30 seconds, so let's call n how many times it happens, and the t the total time:
n = t/30
If the height doubles one time, it is multiplied by 2, if it doubles 2 times, it's multiplied by 2², for n times, it is multiplied by 2ⁿ, so for an initial height equal to 3:
Okay, I think I understand.
Straight lines have a measure of 180°, so
52° + 59° + y = 180°
y = 69°
The measure of the inner angles of a polygon = (n - 2)180° where n is the number of sides. The shape is a triangle, so n = 3.
(3 - 2)180° = 63° + y + x
180° - 63° - (69°) = x
x = 48°
Answer:
(x-3) (x-9) or (x-9) (x-3)
Step-by-step explanation:
1) what * what=27
and what+what=-12
factors of 27: 9,3 -9,-3 1,27 -1,27
-9+-3=-12
hence -9 and -3 are our factors
(substitute -9 and -3 in place of -12)
x^2-9x-3x+27
split into two groups:
x^2-9x
(both have a gcf of x)
x(x-9)
and
-3x+27
(both have a gcf of "-3"
-3(x-9)
take the numbers OUTSIDE the parantheses and put them in a bracket:
(x-3) (x-9)
