Answer:
k = 13 The smallest zero or root is x = -10
===============================
Work Shown:
note: you can write "x^2" to mean "x squared"
f(x) = x^2+3x-10
f(x+5) = (x+5)^2+3(x+5)-10 ... replace every x with x+5
f(x+5) = (x^2+10x+25)+3(x+5)-10
f(x+5) = x^2+10x+25+3x+15-10
f(x+5) = x^2+13x+30
Compare this with x^2+kx+30 and we see that k = 13
Factor and solve the equation below
x^2+13x+30 = 0
(x+10)(x+3) = 0
x+10 = 0 or x+3 = 0
x = -10 or x = -3
The smallest zero is x = -10 as its the left-most value on a number line.

A jazz band sells 31 large boxes of fruit and 74 small boxes of fruit for a fundraiser.
a. Write and simplify an equation using distributive property to find the profit.
b. A large box of fruit costs $9 and a small box of fruit costs $4. What is the Jazz's band profit?
Profit = Price - Cost
Large Fruit Box:
Price $20
Cost $x
Small Fruit Box
Price $10
Cost $y

Because the <span>reciprocal is the opposite so it would be canceling out one side while moving it to the other. It's kind of like dividing by 3/5</span>
