14.2h-10.3. Substitute 25.8 for h.

4=8h. Substitute 6 for h.

4.5 - d > 2.5. Substitute 2.5 for d.

832p. Substitute 12for p.

w2<32. Substitute 16 for w.

Answer 1

1st one is true

3(4) is not > 15

8(4) is not < 2

14.2(25.8)-10.3

=366.36-10.3

= 356.06

4=8(6)= 48

4.5-2.5 is not > 2.5

832(12)= 9984

16(2) is not <32
