Answer:
height = 7 cm
Step-by-step explanation:
The area (A) of a trapezium is calculated using the formula
A = 
h(a + b)
where h is the height and a, b the parallel bases
here a = 6, b = 12 and A = 63, hence
× h × (6 + 12) = 63
h × 18 = 63
9h = 63 ( divide both sides by 9 )
h = 7
Step-by-step explanation:
whaaaaaat ........how do we know that
Explanation:
The cost for the ad can be calculated as:
Cost = $29 + 3.45(3) + $20
Cost = $59.35
Because the ad has 7 lines, 4 that are include in the initial
distance b/w points M(6,-6) and Z(2,-3)
= √(-6+3)^2 + (6-2)^2)
= √( 3)^2 + 4^2
= √(9+16)
=√25
= 5
