Answer:
-24b - 16c - 36a = -28
Step-by-step explanation:
Given the initial equation of 9a + 6b + 4c = 7 and looking at the second equation of -24b - 16c - 36a, I notice that all of the coefficients of the variables have been multiplied by a factor of -4. Since all of the factors have been multiplied by the same factor, multiplied the answer to the equation by a -4 as well will give us the answer to the problem. Since the original answer is 7, multiplying this answer by a factor of -4: (7)(-4) = -28.
Answer:
Step-by-step explanation:
Area = pi*r^2
Area = pi*9^2
Area =
If the roots are r1,r2,r3, the facotred polynomail looksl ike this
f(x)=(x-r1)(x-r2)(x-r3)
given
roots 4,2i and -2i
f(x)=(x-4)(x-2i)(x-(-2i))
f(x)=(x-4)(x-2i)(x+2i)
expand
f(x)=x³-4x²+4x-16
3rd option
Well if we times twenty miles with eight hours the answer is 160 miles
Answer:
Step-by-step explanation:
In 2x/(x^2 - 1)1/2
Apply the property of natural log
ln x^m = m ln(x) move the exponent before ln
ln(m/n)= ln m - ln n
multiply 1/2 inside the terms
