X^2-7x-34=10<br><br> Please help me answer this question thank you

elena-s [515]

Answer: x = 4,11

Step-by-step explanation:

x^2 - 7x - 34 - 10 = 0

x^2 - 7x - 44 = 0

Factorise it

x^2 - 11x - 4x - 44 = 0

x ( x - 11 ) - 4 ( x - 11 ) = 0

(x-4)(x-11) = 0

x = 4,11

So firstly, let's figure out the expression for a singular goody bag. Since there's 2 of each item, a single goody bag is going to be $(1.07*2+0.85*2+2.12*2)$

Now since we have 7 friends who are all getting 1 goody bag, multiply the cost of the goody bag by 7, and our expression is $7(1.07*2+0.85*2+2.12*2)$ . Now we can solve it from there.
