A = 1/2 bh
A = 1/2 • (6x + 4)(x-7)
Use FOIL to multiply the binomials
A = 1/2 • 6x^2 - 3x - 28
Multiply the (1/2) in
A = 3x^2 - 3/2x - 14
Final answer!
Sub x=3 into ((x^2)-x)^2 - (x^2 - x) = 30. So the answer is A.
Answer:
48%
Step-by-step explanation:
P (not getting a speckled rock) = 12/18 = 2/3
P (not getting a green rock) = 13/18
2/3 * 13/18 = 26/54 = 13/27 ≈ 48%
Answer:
B. x ≥ 1
Step-by-step explanation:
Step 1: Subtract 6x from both sides
4x + 16 ≥ 20
Step 2: Subtract 16 from both sides
4x ≥ 4
Step 3: Divide both sides by 4
x ≥ 1
And we have our answer!
