The fact family model represents 3 + 14 = 17. A triangle. 17 is in the top corner. 3 is in the bottom left corner. 14 is in the bottom right corner. How does 17 compare to 3? 14 is 17 less than 3. 3 is 14 less than 17. 3 is 17 greater than 14. 3 is 14 greater than 17.

3 is 14 less than 17

Step-by-step explanation:

Given the model:

3 + 14 = 17

Say :

A = 17

B = 3

C = 14

Comparing 3 to 17 in the model :

We can express 17 interms of 3 and 14

3 + 14 = 17

17 is the sum of 3 and 14

Therefore, 17 is 3 greater than 14 or 14 greater than 3

14 = 17 - 3

14 is 3 less than 17

3 = 17 - 14

3 is 14 less than 17

From the options , the correct statement which models the comparison between 17 and 3 is ;

"3 is 14 less than 17".

step-by-step explanation:

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
