Answer :
(1)
Use FOIL method to mulitply (3x – 5)(3x – 5)
(2)
Use FOIL method to mulitply (3x - 5)(3x + 5)
(3)
Use FOIL method to mulitply -(3x + 5)(3x + 5)
(4)
Use FOIL method to mulitply -(3x + 5)(3x - 5)
So equation 2 is true

Answer : The volume blue prism in Model 1 is,
Step-by-step explanation :
As we are given that:
Volume of Model 1 = Volume of Model 2
Given:
Volume of blue prism in Model 2 =
Volume of orange prism in Model 2 =
Volume of orange prism in Model 1 =
Now we have to calculate the total volume of Model 2.
Total volume of Model 2 = =
Now we have to calculate the volume blue prism in Model 1.
Volume of Model 1 = Volume of Model 2
Volume of orange prism in Model 1 + Volume blue prism in Model 1 = Total volume of Model 2
+ Volume blue prism in Model 1 =
Volume blue prism in Model 1 =
Volume blue prism in Model 1 =
Thus, the volume blue prism in Model 1 is,

Answer:
M(6,5) and G(2,9)
Step-by-step explanation:
B(3,6)
C(9,4)
m = [(3+9)/2 , (6+4)/2]
= (6,5)
M(5,9)
H(8,9)
G(x,y)
[(x+8)/2 , (y+9)/2]=(5,9)
(x+8)/2 = 5
x+8 = 10
x = 2
(y+9)/2 = 9
y+9 = 18
y = 9
G(2,9)
