Answer:
k = 13The smallest zero or root is x = -10
Step-by-step explanation:
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:
The bench cost $325
Step-by-step explanation:
Garden Table + Bench = $742
g + b = $742
Garden Table - Bench = $92
g - b = $92
g = $92 + b
Substitute g into total cost equation
$92 + b + b = $742
$92 + 2b = $742
2b = $650
b = $325
The bench cost $325
Hope this helps :)
