Answer: A = - 0.64
Divide each term in
6
(
a
+
3.9
) = 19.56 by 6
6
(
a
+
3.9
)/
6 = 19.56/
6
Cancel the common factor of 6
a + 3.9 = 19.56
/6 Divide 19.56 by 6
, a
+
3.9 = 3.26
49x^2 - 9 = 0
As there is no x term, we can pretty much guess we have a situation where we factlrise by something known aa difference of two squares, so to factorise it:
49 = 7^2
9 = 3^2
x^2 = (x)^2
so...
(7x - 3)(7x + 3) = 0
7x - 3 = 0 7x + 3 = 0
x = 3/7 x = -3/7
The problem doesn’t make sense :(
Answer:
The awnser for that is -2, my friend
