Answer:
Length of grey rod is 
th of the white rod.
Step-by-step explanation:
Let the length of each black rod = b units
Length of 2 black rods = 2b
Length of each grey rod will be = g units
Length of 3 grey rods = 3g
Since, length of 2 black rods = length of 3 grey rods
2b = 3g ----- (1)
Length white rod = Length of 2 black rods + Length of 3 grey rods
w = 2b + 3g
From the equation (1),
w = 2b + 2b
= 4b
b = 
Therefore, length of grey rod is th of the white rod .
Answer:
23x^2
Step-by-step explanation:
When adding variables, if they have the same exponent then all that needs to be done is add the constants. In this case both have x^2 so the answer is 23x^2. Hope this helps! :)

Answer:
c = 8.06
Step-by-step explanation:
Use the Pythagorean theorem.
a^2 + b^2 = c^2
c^2 = a^2 + b^2
c^2 = 4^2 + 7^2
c^2 = 16 + 49
c^2 = 65
c = sqrt(65)
c = 8.06
