Adi used algebra tiles to represent the product . which is true regarding adi’s use of algebra tiles?

a. she used the algebra tiles correctly.

b. she did not represent the two original factors correctly on the headers.

c. the signs on some of the products are incorrect.

d. some of the products do not show the correct powers of x.

The answer is not A it might be C

Step-by-step explanation:

It shows that she did not place the tiles correctly therefore A is out, the signs of the sum are incorrect so therefore might be C

i think its a

Step-by-step explanation:

i can

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
