Answer:
A.
Step-by-step explanation:
Step 1: Factor out GCF
-2x(x² + 7x + 6)
Step 2: Factor quadratic
-2x(x + 1)(x + 6)
So A is our answer.
(0,4) u (9, infinity)
why? you want to use parentheses because it says "less than" More than" not "4 or less" which would mean you use brackets because that includes the number
X/2 + y/3 = 6....multiply by common denominator (6) to get rid of fractions..
3x + 2y = 36
3x + 2y = 36
x - y = 2....x = y + 2
3(y + 2) + 2y = 36
3y + 6 + 2y = 36
3y + 2y = 36 - 6
5y = 30
y = 30/5
y = 6
x - y = 2
x - 6 = 2
x = 2 + 6
x = 8
solution is : (8,6)
Answer:
12x^2; 21
Step-by-step explanation:
4x^2-3=4×1.5^2-3=6
4x^2-2=4×1.5^2-2=7
4x^2-1=4×1.5^2-1=8
6+7+8=p=21
