= 8y^2 - 32y + 3y^2 + 6y
= 11y^2 - 26y
Y=4x^2+16x-48
Start with factoring (x-2)(x+6) using distribution
Then multiply it by 4
Standard deviation is the square root of the variance.
To find the variance from the standard deviation, raise it to the 2nd power:
Standard deviation = 4
Variance = 4^2 = 4x4 = 16.
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
Step-by-step explanation:
I think it is the last one.
