Answer:
x=-3 x=-2
Step-by-step explanation:
x^2+5x+6=0
Factor
What 2 numbers multiply to 6 and add to 5
3*2 =6
3+2=5
(x+3)(x+2) =0
Using the zero product property
x+3 =0 x+2=0
x=-3 x=-2
Answer:
the expression is x= 2.5 * z/√y
Step-by-step explanation:
since x is proportional to z and since x varies inversely as the square root of y
x= a * z/√y
then
a = x*√y /z
replacing values
a = x*√y /z = 6*√25 /12 = 30/12 = 10/4=2.5
therefore
x= 2.5 * z/√y
F(x) = 5x - 6 and g(x) = x^2 - 5x + 6
(f - g)(x) = 5x - 6 - x^2 + 5x - 6 = -x^2 + 10x - 12
(f - g)(x) = -x^2 + 10x - 12
Answer:
4.925
Step-by-step explanation:
first you minus 20.8 from 1.1, after that you divide 19.7 by 4 and that's is how you would get 4.925.
Square root of 64 is 8. 8x8=64
cube root of 64 is 4. 4x4x4=64
