Answer:
wea did tha r come from??
Step-by-step explanation:
it is supposed to be d
5.3 or 28
+=
36+=64
64-36=28
=5.29 or 5.3
$36
20x.80=16
20+16=36
Hence, the original price is $36
Expand the binomial first, then distribute the 4:
4 (<em>x</em> + 1)² = 4 (<em>x</em> ² + 2<em>x</em> + 1)
… = 4•<em>x</em> ² + 4•2<em>x</em> + 4•1
… = 4<em>x</em> ² + 8<em>x</em> + 4
I think − 4 ⁴ − 5 ²
I might be wrong.
