5. Why is it not possible to make a right triangle using lengths of 10 feet, 60 feet,
and 65 feet?
A 10 +60 is greater than 65.
B 65 - 60 does not equal 10.
C 102 + 60 does not equal 652
D (10+60) does not equal 65

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

its 60

4 x 12 = 48

3 x 4 = 12

48 + 12 = 60

yeeeet
