Answer:
k = 25
Step-by-step explanation:
(2x - sqrt(k) )^2 Expand this as a binomial
4x^2 - 4x*sqrt(k) + k The middle term must be -20x Solve for k so it is
-4xsqrt(k) = - 20x Divide by -4x
sqrt(k) = -20x/-4x Do the division
sqrt(k) = 5 Square both sides
k = 25
8p, -70, and 4 z are the terms and 4z and 8p are coefficient.
Answer:
the answer s 6 and seventh squared so it's a 7 on the top of the 6
Step-by-step explanation:
first what your do is decide 6'5 and 6'2 and you would get 6'3. so just multiply 6'3 and 6'4 and you should get 6'7
Answer:
f(-5)=240
g(-7)=-33
Step-by-step explanation:
1) f(x)=3x^2 - 3x
f(-5)= 3×(-5)^2 - 3×(-5) = -15^2 + 15= 225 + 15=240
2) g(x)=5x + 2
g(-7)= 5×(-7) + 2= -35+2=-33
