Hello :
<span>f(x)=x²+4x-5
</span><span>The axis of symmetry for a function in the form f(x)=x^2+4x-5 is x=-2 :
</span>f(x) = (x+2)² + b
f(x) x²+4x+4+b= x² +4x-5
4+b= -5
b = -9

Find x and IJ is HK is an altitude of triangle HIJ

ss7ja [257]

3x+3=90
subtract 3 from both sides
3x=87
divide both sides by 3
x=29

To find IJ, plug in the x value
x+8+x-9
29+8+29-9
57=IJ
