The equation for the area of a circle is:
. Insert 9 as your radius (r) into the equation and solve:
\pi 9^2 = 254.469
Answer:
D. (x - 2)(x - 2)
Step-by-step explanation:
x2 - 4x + 4 = x² - 2x - 2x +4
= x(x-2) - 2(x - 2)
= (x-2)(x-2)
HINT: - 2x +4 = -2 * x + (-2) * (-2) = -2 ( x -2)
First write the equation
3/n = 5
Multiply both sides by n
3/n * n = 5 * n
Simplify
3 = 5 * n
Divide both sides by 5
3/5 = 5 * n/5
Simplify
3/5 = n
Divide
0.6 = n
So 3/0.6 = 5
1. The answer is two because if you factor what you can from the equation and then simplify, you are left with 2v+16=(v+8)(?), and by looking at it, the correct answer is two, or A. Review your work, make sure to check your answers before submitting
2. Since two simple factors of 8 are 4 and 2, and they add up to 6, the correct answer is (x+4)(x+2), or B
3. Again, two simple factors of 12 are -4 and -3, so the correct answer is (x-3)(x-4), or D
4. Basically, just factor the quadratic trinomial g^2-2g-24, which turns out to (G+4)(g-6), which is B
