Answer:
(x-3)(x^2-7) = x^3 -3x^2 -7x + 21
just change the sign of the root and put x in front of it, then multiply the factors all together
(x-3)(x-sqr7)(x+sqr7) roots come in conjugate pairs to eliminate irrational coefficients
(x-sqr7)(x+sqr7) = x^2-7. similar to (a-b)(a+b) = a^2-b^2
Step-by-step explanation:
Answer:
6√3
Step-by-step explanation:
Use the sin formula, which is sin = opp / hyp
sin 60 = x / 12
x = 12 sin 60
x = 6√3
2.
you had nothing for 1. and I am not sure what you mean by 4.
This is a list of all answers
Jenna is correct. This is because the square root of 2 is an irrational number. And if the number is a prime number, the answer is less likely to have a rational square root.
24 cans = 2 cans
$x $9
2x= 260
x=180
24 cans/ $108= 2 cans/ $9
