Just trying to figure out -2(g+5) ‍♀️

−2g−10

-2 times g will give you -2g

then you do it on both sides so -2 times 5

and that gives you -10

so it gives you -2g-10.

the answer is -2g-10

Step-by-step explanation:

all u need to do is multiply the g and the 5 with the -2 which then gives u -2g-10

the answer is 375 miles

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
