Step-by-step explanation: This is because 1/2 is .5 in decimal form. A negative <em>PLUS </em>a positive = is negative since the <em>-20 i</em>s larger than .5

If x is an integer, what is the least possible value of x for a rectangular lot
AlexFokin [52]

Answer:

k = 13The smallest zero or root is x = -10

===============================

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

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.

Step-by-step explanation: Hope this helps kind of.
