Answer:
h(x)=x²+6 and g(x)=8x-5
prove that hg(x)=19
Step-by-step explanation:
step 1: hog(x)=h[g(x)]
step 2: h(8x-5)
step 3: h(8x-5)= (8x-5)²+6
step 4: (8x-5)(8x-5)+6
step 5: 16x² +15x +6
Hello,
x^3+7x^2+10x-6=x^3+3x^2+4x^2+12x-2x-6
=x²(x+3)+4x(x+3)-2(x+3)
=(x+3)(x²+4x-2)
=(x+3)(x+2-√7)(x+2+√7)
zeroes={-3,-2+√7,-2-√7}

I might be wrong, but hopefully that helped! :)
Answer:
-7 = h
Step-by-step explanation:
15.3 + 1h = 1.3 - 1h
<u> +1h +1h</u>
15.3 + 2h = 1.3
Remember what you do to one side you MUST do to the other.
15.3 + 2h = 1.3
<u>-15.3 -15.3</u>
2h = -14
Now to isolate the variable you divide both sides by 2 to get, h = -7
Hope that helps and have a great day!
