Weegy: If it is growing 2% each year, then after the 1st year it will be 1500 x 1.02. Then using the new total you got for the first year, you do it for the next 3 years by multiplying with 1.02 each time to get it for all 4 years. [ Hence it goes: 1500 x 1.02=1530. 1530 x 1.02 = 1560.6. 1560.6 x 1.02 = 1591.812. 1591.812 x 1.02 = 1623.65. ]
User: Factor the polynomial.
54c3d4 + 9c4d2
A. 9c3d2(d2 + 6c)
B. 9c3d2(6d2 + c)
C. 9c4d2(d2 + 6)
D. 9c4d2(6d2 + 1)
Weegy: The answer is B. 9c3d2(6d2 + c)
User: A machinist creates a washer by drilling a hole through the center of a circular piece of metal. If the piece of metal has a radius of x + 10 and the hole has a radius of x + 6, what is the area of the washer?
Weegy: Solution:
Area of Washer = Area of Metal - Area of the hole
A=pi(x+10) 2 pi(x+6) 2
this will expand to
A=pi(x 2 +20x+100 x 2 12x 36)
collecting like terms
A=pi(8x++64)
or A=8pi(x+8) answer
User: What is the factored form of the expression?
12d2 + 4d – 1
A. (6d + 1)(2d + 1)
B. (6d – 1)(2d – 1)
C. (6d – 1)(2d + 1)
D. (6d + 1)(2d – 1)
Weegy: 12d2 + 4d ? 1 is equal to: C. (6d ? 1)(2d + 1)
User: What is the factored form of the expression?
3x2 + 8x – 16
A. (3x + 4)(x – 4)
B. (3x + 4)(x + 4)
C. (3x – 4)(x – 4)
D. (3x – 4)(x + 4)
Weegy: D. (3x ? 4)(x + 4) is the factored form of the expression.
User: Simplify the product using the distributive property.
(3h - 7)(3h - 6)
A. 9h2 + 3h - 42
B. 9h2 - 3h - 42
C. 9h2 - 39h + 42
D. 9h2 + 39h + 42
Weegy: (3h - 7)(3h - 6) = C. 9h2 - 39h + 42
User: (–7x – 5x4 + 5) – (–7x4 – 5 – 9x)
A. 2x4 + 2x + 8
B. –14x4 + 10x + 10
C. –14x4 – 10x + 10
D. 2x4 + 2x + 10
Weegy: Assuming the 4's are exponents: ( 7x ? 5x^4 + 5) ? ( 7x^4 ? 5 ? 9x) = D. 2x^4 + 2x + 10.

(4w^2 – 7w – 6) – (8w^2 + 2w – 3)
= 4w^2 – 7w – 6 – 8w^2 - 2w + 3
= (4w^2 – 8w^2) + (-7w - 2w) + (-6 + 3)
= -4w^2 - 9w - 3
