5g + 14 - 3g -5 (marking the right answer as brainest)​

=2g+9

Step-by-step explanation:

5g+14−3g−5

=5g+14+−3g+−5  

=5g+14+−3g+−5

=(5g+−3g)+(14+−5)

=2g+9

2g + 9

Step-by-step explanation:

5g + 14 - 3g -5=

2g + 14 -5=

2g +9

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

on a coordinate grid, point a is at (−4.0, −2.4) and point b is at (4.0, −2.4). point b is a reflection of point a across the –axis. input either a lowercase x or i think is the right awnser
