Iset it to 25 use the distributive property to write an equivalent expression 1. 5y + 10 2. 10n + 15g the expression 10n + 13n + 75 represents the total cost in dollars for skis, boots, and a lesson for n skiers. simplify the expression. then find the total cost for 7 skiers.

See below

Step-by-step explanation:

1. 5y+10

divide by 5

5(y+2)

2. 10n+15g

divide by 5

5(2n+3g)

10n+13n+75

add like terms

23n+75

You cannot simplify more because 23 is a prime number

n=7

substitute for n

23(7)+75

multiply

161+75

add

236

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
