Rewrite the expressions by using the distributive property and collecting like terms. 1/6(12s + 6)
Citrus2011 [14]

For the distributive property, multiply the number outside the parentheses by each term inside the parentheses.

1/6 x 12s = 2s

1/6 x 6 = 1

Now combine them to get the final answer: 2s + 1

Extraneous solutions, is answers that we get because of squaring both sides of the radical equation, but in reality, they are not going to be the solutions of  the given equation.
(√(4x+41))²=(x+5)²
4x+41=x²+10x+25
x²+6x-16=0
(x-2)(x+8)=0
x1=2 , x2=-8,
And now we must to check them by substitution into initial equation

√(4x+41)=x+5
1)   x=2,   √(4*2+41)=2+5, √49=7, 7=7 true
2) x=-8,     √(4*(-8)+41)=-8+5,   √9 =-3    false,
so an extraneous solution x=-8

tensa zangetsu [6.8K]
The equation is 2.50÷5=x
2.50÷5=.50
Mrs. Baker paid $2.50 for 5 pounds of bananas
If x=.50 per banana
Then to get the cost of 8 bananas, you would do 8×.50=$4.00
Mrs. Baker paid $4.00 for 8 pounds of bananas
Each banana costs .50 cents per pound
