4 0

Answer:

The terms are not equivalent

Step-by-step explanation:

-8 - 2(3+2n)+7n

Distribute the 2

-8 -6-4n+7n

Combine like terms

-14 +3n

That is not equal to -30 -13n

The terms are not equivalent

WHERE DO THE NUMBERS GO? help!!!!!!
Marat540 [252]

Answer:

Other: \frac{3}{4} , 0.25

Whole Numbers: -20, -6

Natural Numbers: 532, 10, 0, \frac{6}{2}

Step-by-step explanation:

Natural numbers have to be positive whole numbers such as 10 and 0

Whole numbers are similar, but you can have negative numbers here. You just can't put fractions in there.

The 3rd section is a little odd, Integers don't use fractions or decimals, same as whole numbers. The fractions and decimal numbers would go outside of that section.

Extra note: \frac{6}{2} might be a tricky one because it is in fraction form but it is also written as 3. This means it is a natural number. The reason numbers such as \frac{3}{4}  and 0.25 are not natural numbers is because they cannot be put as whole numbers.

In the coordinate plane, what is the length of the line segment that connects points at (5,4) and (-3,-1)
baherus [9]

Answer:

9.434 units

Step-by-step explanation:

Given data

points (5,4) and (-3,-1)

x1= 5

y1= 4

x2= -3

y2= -1

The expression for the distance between two points is

d=√((x_2-x_1)²+(y_2-y_1)²)

substitute

d=√((-3-5)²+(-1-4)²)

d=√((-8)²+(-5)²)

d=√64+25

d=√89

d=9.4339

d= 9.434 units

Hence the distance between the points is 9.434 units

If mAD=85 degrees and mBC=31 degrees find the value
Eddi Din [679]
Answer: x = 11

To start, we know that a whole circle equals 360 degrees. If we subtract the 2 arcs we know, 85 and 31, we have 244 degrees left for the 2 congruent arcs. Dividing that by 2 gives us 122 for each arc.

Now, write the equation:  122 = 13x - 21

Solve this, to find the x = 11.
