#4. Juan has a total of $40 to spend on a party for his friends. He bought
some pizza and drinks for $25 and he also wants to get some bags of
candy for $3 each. Which Equation can be used to determine how many
bags of candy Juan can buy for the party? (click A, B, C or D at the
bottom) *
A. 25x + 40 = 3
B.
40x + 3 =25
C. 3x + 25 = 40
D.
25 + 40 + 3 = x
A

the answer is simply just 6n add the two together as they have an n

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
