Both triangles are right triangles as shown by the right angle marks in the figure.
Two corresponding legs are congruent as shown.
The diagonal is congruent to itself, and it is the hypotenuse of both right triangles.
its 60-10+x why, because she bought the dress with $60 and she received $10 dollars back. We don't know the variable.
Answers: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
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.
