Answer:
a must be 9
Step-by-step explanation:
Divide both sides of the given equation by 0.75, to isolate (a - 2):
a - 2 = 5.25/0.75 = 7
Then a - 2 = 7, and so a must be 9.
h = 22 units
area = 1/2bh
165 = 1/2(15)h
15h = 330
-2
0.9x + 2.3x = -6.4
3.2x = -6.4
x = -2
the left side of the line
X intercept =6
Y intercept =3
hope this helps
