This is a difference of perfect square so you get (2x+6)(2x-6)=0, solving will give you 3,-3
Answer:
47/69 is 0.68115942..as so on.... so it is non terminating not recurring
Step-by-step explanation:
it's not repeating any particular pattern.
[(51 + 3) - 3^2] / 9 *2
[(54) - 9] / 9 * 2
[45] /9 * 2
5 * 2
10
remember PEMDAS
Answer:
a. 42, 48
Step-by-step explanation:
The angles being complementary means their total measure is 90°.
(12q -9) +(8q +14) = 90
20q +5 = 90 . . . . . . . . . . . simplify
20q = 85 . . . . . . . . . . . . . . subtract 5
q = 4.25 . . . . . . . . . . . . . . . divide by 20
Now, put this value into the expressions for the angle measures:
12q -9 = 12·4.25 -9 = 42
8q +14 = 8·4.25 +14 = 48
These two angle measures total 90, so our answer checks OK.
The measures of the angles are 42 and 48 degrees.
