3x + 4
2x + 5|6x² + 23x + 20
6x² + 15x
8x + 20
8x + 20
0
The answer is B.
(2n³ + 4n² - 7) + (-n³ - 8n - 2)
(2n³ - n³) + 4n² - 8n - 7 - 2
n³ + 4n² - 8n - 9
The answer is B.
2x² - 10x - 12
2(x²) - 2(5x) - 2(6)
2(x² - 5x - 6)
2(x² - 3x - 2x - 6)
2(x(x) - x(3) - 2(x) - 2(3))
2(x(x - 3) - 2(x - 3))
2(x - 2)(x - 3)
The answer is A.
4ab - 8a² + 12ac = 4ab - 8a² + 12ac = b - 2a + 3c
4a 4a 4a 4a
The answer is B.
Answer:
33
Step-by-step explanation:
Simplify the expression.
0 = 2x^2 + 5x -3
0 = (2x-1)*(x+3)
2x-1=0 and x+3=0
X= 1/2 and x = -3
Y= 2(0)^2 + 5(0) - 3
Y = -3
Answer:
19 sides
Step-by-step explanation:
Sum of angles of n-side polygon = 180 *(n - 2)
180 *(n -2) = 3060
Divide both sides by 180
n- 2 = 3060/180
n - 2 = 17
n = 17+2
n = 19
Answer: y = 31
Step-by-step explanation:
The equation of a line is y = mx+b
Plugging in the values, we get
y = 4*8 + (-1)
y = 32-1
y = 31
