Answer:
E) b^2
Step-by-step explanation:
Solving the first equation for a, we get ...
a - b = 0
a = b . . . . . . add b to both sides
Now, the expression ab can be rewritten as
ab = bb = b^2 . . . . . . substitute b for a
Answer: 70
Step-by-step explanation:
a^2 + b^2 = c^2
24^2 + b^2 = 74^2
576 + b^2 = 5,476
-576 -576
b^2 =4,900
(square root)
b =70
That point of concurrency is called the incenter of the triangle
Your answer is the first one q
Mass = 100 g
Volume = 50 cm³
Density :
D = m / V
D = 100 / 50
D = 2 g/cm³
answer A
hope this helps!.
