If 2 x __ = 58, then 4 x __ = ___

2 x 28 = 58  and then what u mean abt the sencond part?

Step-by-step explanation:

I'm not sure, this is a bit confusing, but you can try either one of these

Step-by-step explanation:

if 2 x 29 = 58

then, 4 x 14.5 = 58

or

the, 4 x 58 = 232

(-5,-28)

i graphed to on desmos.

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
