Answer:
31 cm
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A = h (a + b)
where h is the height and a, b the bases
Here A = 162, h = 6 and a = 23 , then
× 6 (23 + b) = 162
3(23 + b) = 162 ( divide both sides by 3 )
23 + b = 54 ( subtract 23 from both sides )
b = 31
The other base is 31 cm
Answer:
6y^2-7y-3
Step-by-step explanation:
<u>(-7-10y+6y^2)+(4+3y)</u>
<u>-7-10y+6y^2+4+3y </u><u><em>(Plus before brackets means the numbers stays the same)</em></u>
<u>6y^2+3y-10y+4-7</u><u><em> (Arrange them)</em></u>
<u>6y^2-7y-3 </u><u>(Do the maths)</u>
