Answers:
k = 13The 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.
        
             
        
        
        
P=-1/4
Work: 
-3(2+4p)=2(2p-1) distributive property space now it’s -6-12p=4p-2
-6-12p=-4p-2 add 4p on both sides
-6-16p=-2 add 6 on both sides
-16p=4 divide both sides by -16
P=-1/4

Answer:
the 1st number line and 29
Step-by-step explanation:
The second one starts at 21 and takes away which gives 13. which isnt the answer. When adding numbers, you go forward
