(n-m) out of n
not sure if this is correct or something....
Slope is -1

X Intercept 4
Sorry I do t know the others
Haven’t gone over that
Hope this helps
The answer is
the first one is x= 18.98
a^2+b^2=c^2
8 cm^2+17 cm^2= x^2
64+289=x^2
√x^2= √353
x=18.89
<span><span>the second one is x= 18.7
a^2+b^2=c^2
7 m^2+ x^2= 20 m^2
49 m+x^2=400 m
-49 -49
</span></span>√x^2=√352
<span><span>x= 18.7
Hope this helps!</span></span>
A, C. A is obviously correct because it’s the e same thing and C you combine like terms (2n+n=3n,2+4=6,=3n+6) it’s not B because it’s not 18, it’s not D because you’d get 3n+18 and it’s not E because you’d get 3n+12, meaning the only correct answers are A and C
