Determine the Blocks Each Girl Has 10
Linda, Mary, and Monica have a set of 9 blocks, numbered 1 through 9:
1 2 3
4 5 6
7 8 9
Each girl takes 3 of the 9 blocks.
Linda says: The product of all my numbers is 63.
Mary says: The product of all my numbers is 48.
Monica says: The sum of all my numbers is 16.
Determine the blocks each girl has. Discuss the answer with your teacher.​

i don't have the answer rn but go to math papa. it shows the steps and the answer. hope this : )

step-by-step explanation:

i think it is 18

step-by-step explanation:

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240
