1. D 4n -2. Two less = subtraction. 4 times(multiplication) a number n = 4n. Since we need 2 less than 4 times a number two, we need to subtract 2 from 4n.

2. B 50 - X. Sam had $50 dollars before he bought CDs(X). So we subtract X from $50 to find how much money Sam has left after spending (subtraction) X.

3. A. Rational
C. Integer
D. Whole

5. C. Distributive Property.

6. D. 13a + 3. 5(a + 3) - 4(3 - 2a) This makes use of the distributive property.
5(a + 3) = 5 x a + 5 x 3 = 5a + 15. -4(3 - 2a) = -12 -4 x -2a = -12 + 8a (a minus times a minus is always a positive). So now we have 5a + 15 - 12 + 8a. We can rewrite this as 5a + 8a + 15 - 12. 5a + 8a = 13a. 15 - 12 = 3. 13a + 3

7. C. $50.00 + $20.00 + 2($35.00) -2($10.00)
Deposit = Addition. Withdrawl = Subtraction. 1. 50 deposit(+) 2. 20 Deposit(+). 3. 2 Deposits(+) of 35 = 2(35) ::Distributive Property. 2 Withdrawls(-) of 20 = -2(20) ::Distributive Property.

A 42-inch board is to be cut into three pieces so that the second piece is twice as long as the first piece and the third piece

Karo-lina-s [1.5K]

Answer: 7 inches

Step-by-step explanation:

If x is the first piece, and the second piece is twice as long, then the second piece is 2x.

If the third piece is three times as long as the first piece, x, then the third piece is 3x.

The 42-inch board must be equal to all 3 pieces, so we will set up an equation and solve for x.

42 = x + 2x + 3x

42 = 6x

7 = x

The first piece is 7 inches long.

GARDEN Amanda is planting flowers in a rectangular garden. She wants to know the amount of space in her backyard the garden will

Andrew [12]

The function A(x) = 2x²-3x-2 represents the area of the garden.

Step-by-step explanation:

Given,

Length of rectangular garden is given by;

L(x) = 2x+1

Width of rectangular garden is given by;

W(x) = x-2

Area of rectangular garden;

A(x) = L(x) * W(x)

$A(x) = (2x+1)(x-2)\\A(x) = 2x(x-2)+1(x-2)\\A(x) =2x^2-4x+x-2\\A(x) = 2x^2-3x-2$

The function A(x) = 2x²-3x-2 represents the area of the garden.

What is the answer to this question

Lesechka [4]

Remark

There's a lot you don't know here. Are DE and GF parallel? Is B a right angle? You can't assume that it is. The safest way to proceed is to give x in terms of 58 and B. You might get an answer that gives you something like 32 but I don't think you can say that unless you are told somewhere that ABC is a right angle triangle with the right angle at B.

So what to do.

<BAC = 58o That's because <BAC = <IAK They vertically opposite.

<ABC + <BAC + <ACB = 180o All triangles have 180o

<ACB = 180 - 58 - <ABC Solve for an unknown angle of a triangle.

<ACB = 122 - <ABC

x = <ACB Vertically opposite angles.

x = 122 - <ABC Answer It's 32 if ABC is a right angle.

Sector problem please help

hammer [34]

Answer:

The answer is (π/4)*r

Step-by-step explanation:

Formula length of arc when the angle given is in radian as the case given

s = r*θ

s = arc length (in radians)

r = radius

θ = central angle in radians

But when the angle given is in degrees the length is expressed as

s= 2πr*(θ/360)
