Answer:
-9h² - 12h - 3
Step-by-step explanation:
Follow the FOIL method:
FOIL = First, Outside, Inside, Last
Multiply the terms together:
First: 9h * -h = -9h²
Outside: 9h * -1 = -9h
Inside: 3 * -h = -3h
Last: 3 * -1 = -3
Combine like terms: 9h² + (-9h - 3h) - 3
9h² - 12h - 3
-9h² - 12h - 3 is your answer.

4 > 6*t
Number t refers to an unknown. In this case, t can only be 0, because 6*0 = 0, and 4 > 0 or four is greater than 0.
Answer:
B
Step-by-step explanation:
-5[ (x³+1)(x+4) ] = -5[ x³*(x+4) + 1*(x+4) ]
= -5 [ x³*x + x³*4 + 1*x + 1*4 ]
= -5 [ x⁴ + 4x³ + x + 4]
= -5*x⁴ + (-5)*4x³ + (-5)*x + (-5) * 4
= -5x⁴ - 20x³ - 5x - 20
Answer: 129.33 g
Step-by-step explanation:
Step-by-step explanation:
first of all, all answer options are basically wrong, because an area is always measured in units² (and not just in units).
the blue colored area is the area of the whole square minus the area of the circle.
the side length of the square is 2 times the radius of the circle (the diameter) : 2×12 = 24 units.
so, the area of the square is
24² = 576 units²
the are of the circle is
pi×r² = pi×12² = 144pi units²
so, the blue area is
576 - 144pi = 123.6106579... ≈ 124 units²
therefore, D is the right answer.
