Answer:
x = 6 cm
Step-by-step explanation:
Given ratio of sides of similar figures = a : b , then
ratio of areas = a² : b²
Here ratio of areas = 5 : 45 = 1 : 9 , so
ratio of sides = 
: 
= 1 : 3
Thus side of B is 3 times side of A
x = 3 × 2 = 6 cm
Answer:
Between 7 and 8
Step-by-step explanation:
6^2 = 36
7^2 = 49
8^2 = 64
9^2 = 81
since 61 is between 7^2 and 8^2, √61 is between 7 and 8
Area of basketball court: 94 x 50 = 4700 square feet
area of football field: 360 x 160 = 57600 square feet
57600 / 4700 = 12.26
so 12 basketball courts
Answer:
y=2x-2
Step-by-step explanation:
2x-y=2
+y +y 1)add y to both sides
2x=y+2
-2 -2 2) Substract 2 from both sides
2x-2=y
y=2x-2 3) Use the Refelxive POE to flip the sides
Answer: 6x^2-84x+294
Step-by-step explanation:
Use the foil method to solve (x-7)^2 and then multiply your result by 6.
