Self Practice 3.1g Ai Ling has a piece of square cloth. The area of the cloth is betwe
12 100 cm. She wants to use the cloth to sew a piece of square t
the surface of a square table. The length of each side of the table
(a) What is the length of the cloth, in cm, that Ai Ling should se
(Assume that the length of the cloth is a whole number.]
(b) Ai Ling plans to decorate the surrounding sides of the tablecle
that is 4.5 m long so that the tablecloth will look nice. Is the
lace enough? Give a reason for your answer.​

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

17

step-by-step explanation:

51/3=17

thus 17 is your answer.

m∠5 + m∠3 = m∠1   is true.

m∠5 + m∠6 = 180 is true

m∠2 +m∠3 = m∠6   is true

m∠2 +m∠3 +m∠5 = 180   is true
