I will give you Brianlyist

1.  2.90$

2. No, because that would be 2.30$

3. I don't know what it means by that but maybe 10 quarters and 4 dimes.

If there is more to the questions this isnt it.

the surface area is 124cm²

step-by-step explanation:

length: 4cm

width: 9cm

height:   2cm

1. 16.64

a^2+b^2=c^2

pr^2=pq^2+qr^2

pr^2=14^2+ 9^2

pr^2=196+81

pr= sqr root of 277

16.64

2. 11.31

c^2-a^2=b^2

18^2- 14^2=b^2

b^2=324-196

b=sqr root of 126

b=11.31

hope it ! (btw im in connections academy to, good luck! )
