Answer:

The commutative property

Step-by-step explanation:

7.6+3.9+2.4=

7.6+3.9= 11.5+ 2.4= 13.9.

If you added 2.4 and 3.9 first

Find the value of x.<br><br> F) 6m<br> G) 7.5m<br> H) 15m<br> I) 21m
Xelga [282]

Answer:

x = 6 m

Step-by-step explanation:

The area (A) of a trapezium is calculated as

A = \frac{1}{2} h (a + b)

where h is the perpendicular height and a, b the parallel bases

Here A = 60, h = 8, a = 9 and b = x , thus

\frac{1}{2} × 8 × (9 + x) = 60, that is

4(9 + x) = 60 ( divide both sides by 4 )

9 + x = 15 ( subtract 9 from both sides )

x = 6 m
