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.

Answer:
720,080 = 700,000 + 20,000 + 80 =
7 * 100000 + 2 * 10000 + 0 * 1000 + 0*100 + 8*10 + 0*1 =
7 * 10^5 + 2 * 10^4 + 0 * 10^3 + 0* 10^2 + 8 * 10

Answer:
<em>28 ; 76 ; 38</em>
Step-by-step explanation:
<em>KL</em> = 
= 
= <em>28</em> units
<em>YZ</em> = 2 × JK = 38 × 2 = <em>76</em> units
<em>LZ</em> = 76/2 = <em>38</em> units
