Answer:
The standard form of the expression (5a+2)(a+4) is 
.
Step-by-step explanation:
Here, the given expression is (5a+2)(a+4).
Now, (5a+2)(a+4) = 5a(a+4) + 2(a+4)
= 
=
or, 
Also, Standard Quadratic form is 
Hence, the standard form of (5a+2)(a+4) is .
A. ∠ACE ≅ ∠ACE
This is correct.
If you set it up in cross multiplication then you would have (x/100 = 45/54) then cross multiply so then i would look like this (54x/4,500) so from there you would divide 54 from 4,500 i hope this helps in any way oh and it should come up to be 83.3333333 which would be 83% lol
