Im assuming that to be the case, so:-
11/12 + 1 3/4
= 11/12 + 7/4
= 11/2 + 21 / 12
= 32 / 12
= 2 2/3 OZ. (Choice D).
1.75 because 42 divided by 4 is 10.5 and 10.5 divided by 6 is 1.75 i might be wrong but i tried
A(base)=6*6=36
A( triangle)=1/2*(base of the triangle)*height( of the triangle)=1/2*6*4=12
one base +4 triangles=36+4*12=36+48 =84 cm²
5n=30+3n You need to exclude the 4 due to for the first 4GB cost $30 then $3 for each additional GB used
