1. 2x+ 4+3x
= (2x+ 3x)+ 4

2. 12 + 5x -8
= 5x + (12-8)

3. 2x^2 + 3x^2 + 4x
= (2x^2+ 3x^2)+ 4x

4. 5ax - 12 - ax
= (5ax -ax) -12

5. 4xy + 2x + 3xy + x
= (4xy+ 3xy)+ (2x+ x)

Hope this helps~

Write the measure -128 30' 45" as a decimal to the nearest thousandth

miv72 [106K]

Minutes are equal to 1/60ths and seconds are equal to 1/3600ths so

-128+30/60+45/3600

-128.5125

-128.513° (to nearest one-thousandth of a degree)

Answer: C) 4.20

Explanation:

Multiply each value with its corresponding frequency:

1*450 = 450
10*35 = 350
50*10 = 500
100*4 = 400
400*1 = 400

Add up the products

450+350+500+400+400 = 2100

Then divide this over the total frequency (450+35+10+4+1 = 500)

So we get 2100/500 = 4.20 as the expected value.

Lines Line D E and Line A B are parallel. Lines D E and A B are parallel. Angles B and D are alternate interior angles. Which an

valina [46]

Answer:

a. angles A and C

b. angles B and D

Step-by-step explanation:

When two lines are parallel, it implies the value of the angle between them is $180^{0}$ . Thus the lines can not meet when extended continuously.

Alternate angles are two equal angles that lie on opposite sides of the transversal line. Alternate Interior Angles are a pair of equal angles on the inner side of two parallel lines.

Since lines DE and AB are parallel with alternate interior angles at B and D, then angles A and C with angles B and D are alternate interior angles.

i.e < A = < C (alternate interior angle property)

<B = < D (alternate interior angle property)
