Answer:
12
Step-by-step explanation:
That means every x wich is greater than 7
72 Centimeters
Explanation:
Formula for area: 1 /2 b · h
b = Base (18 cm.)
h = height (8 cm.)
1 / 2 Base: 9
height: 8
9 · 8 = 72
Therefore the area of the triangle is 72 centimeters
(2*5^2)+4/3^2-5
(2*25)+4/3^2-5
50+4/3^2-5
50+1.7-5
46.7
