Fahed buys 12 stickers for $2 each he also buys 4 sticker albums each album cost twice as much as each sticker fahed has a coupon that gives him $2 off the sticker albums which numerical expression shows how much he spent

12(2)+ 4(2x2)-2(4)

=24+16-8

=24+8

=$32

2 × 12 + 2 × 2 × 4 - 2

Step-by-step explanation:

Given,

The number of stickers bought = 12,

The price of each sticker = $ 2,

So, the cost of all stickers = 2 × 12

Also, the number sticker album = 4,

According to the question,

The cost of each album = 2 × cost of each sticker = 2 × 2

So, the total cost of all album = 2 × 2 × 4

Thus, the total cost of stickers and album = 2 × 12 + 2 × 2 × 4

After getting $ 2 off,

Hence,

The final spending = 2 × 12 + 2 × 2 × 4 - 2

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
