Answer:
Since 100<105<121, 10<square root of 105<11. So the square root of 105 is between 10 and 11.
Step-by-step explanation:
Answer:
Option D is correct, i.e. (4xy - 3z)² = 16x²y² -24xyz + 9z², a perfect square trinomial.
Step-by-step explanation:
Given the expression is (4xy - 3z)².
Using the formula, (a - b)² = a² -2ab +b².
(4xy - 3z)² = (4xy)² -2(4xy)*(3z) + (3z)²
(4xy - 3z)² = 16x²y² -24xyz + 9z²
It is a trinomial expression and we got it from squared binomial.
Hence, option D is correct, i.e. (4xy - 3z)² = 16x²y² -24xyz + 9z², a perfect square trinomial.
The third one shows parallel lines cut by a transversal
4 teammates and 5 bars.
5/4 = 1.25
1.25 = 1 and 1/4
Answer: Each person gets 1 and 1/4 of a bar

The velocity (v) is distance (d) divided by time (t):
v = d/t
v = 60 mph
t = 3 1/2 h = 3.5 h
d = ?
d = v * t
d = 60 * 3.5 = 210 mi
