Answer:
7
Step-by-step explanation:
if h(x)=4 .. that would mean to plug 4 in as x
therefore .. 3(4)-5
3×4=12
12-5=7
Answer:
12 cm
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A =
h (a + b)
where h is the perpendicular height and a, b the parallel bases.
Here A = 45, h = 5, a = 6 and b = ?, thus
45 =
× 5 × (6 + b) = 2.5(6 + b) = 15 + 2.5b ( subtract 15 from both sides )
30 = 2.5b ( divide both sides by 2.5 )
b = 12
The measure of the other parallel side is 12 cm
