Cole is finding the quotient of 78 + 4. He creates this model to help him solve the division problem.
Which statements are true about Cole's work? Check
all that apply.
Cole's model correctly shows that the quotient of 78
+4 is 12 with a remainder of 30.
Cole has not finished modeling this problem.
Cole needs to add another ten block to his model to
show 78
Cole should have divided the 3 extra tens blocks into
30 ones blocks
A complete modelywould show the quotient of 78 + 4
is 19 with a remainder of 2.

the square root of what number? if you add that, then someone will probably answer the question.

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

pretty sure 750 each month!
