Oh my god.
Hi <span>angelaatkinsonca1,
the answer would be 6.
Remember that to find the percentage of any number, you convert the percent to a numerical form and multiply:
10% = 0.10
2% = 0.02
37% = 0.37
and so forth.
So, in this case, 20% = 0.20
To find 20% of the number 30.00, you would just multiply the two numbers together:
30.00 x 0.20 = 6.000
or, just the number 6.
Hope this helps!
Good luck</span>
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
