Answer:
4
Explanation:
1, 4, 16, 64......
mutiply all of the numbers by 4
1*4=4
4*4= 16
16*4= 64
30 seconds for the whole length, so 1 min for 2 lengths meaning 2 • 10 = 20 lengths
Answer:
c = 4

In a perfect square trinomial, the following relationship is true:

In order for the given expression to be a perfect square trinomial:

Solving for 'c':

Therefore, c must be equal to 4.
Answer:
w = y - x is the equation to find w
Where,
w = Weight of the liquid
x = Weight of the empty can
y = Weight of the can with liquid
Step-by-step explanation:
Let
Weight of the empty can = x
Weight of the liquid = w
Weight of the can with liquid = x + w = y
x= 30 grams
w = ?
y= 47.3 grams
y = x + w
w = y - x
= 47.3 - 30
= 17.3
w= 17.3 grams
Therefore, the weight of the liquid is 17 .3 grams
Answer:
C
Step-by-step explanation:
Let g(x) be y
From the (1,4)
When x =1 y =?
These (2x)^2
(2 × 1)^2 = 2 ^2 = 4
