Answer:
x = 5.4
Step-by-step explanation:
since the figures are scaled factors of each other then they are similar.
the ratios of corresponding sides are therefore in proportion, that is
= ( cross- multiply )
4x = 21.6 ( divide both sides by 4 )
x = 5.4

Answer:
B. 1/2
Step-by-step explanation:
y = ax^2 + bx + c
14 = a(0)^2 + b(0) + c
c = 14
10.5 = a(1)^2 + b(1) + 14
10.5 = a + b + 14 ____(i)
8 = a(2)^2 + b(2) + 14
8 = 4a + 2b + 14
4 = 2a + b + 7 ___ (ii)
i - ii
10.5 - 4 = -a + 7
6.5 = -a + 7
a = 7- 6.5
a = 0.5
