DOES ANYONE KNOW HOW TO SOLVE THIS? EXPLANATION IS MUCH NEEDED!!!

Answer:

1. 2(a^2 + 3a + 9)

2. 5(x^2 - 1)

3. 3(t + 8)(t - 2)

4. n(4 - n)

Step-by-step explanation:

For 1, you can only factor out the constant from each.

For 2, you can also only factor out the constant, but remember that you include the 1 when dividing 5 by 5.

For 3, you can factor out the constant and the variables.

For 4, you can only factor out the variable.

The sample space is

S= {BH,GH,YH,OH,BT,GT,YT,OT}

Step-by-step explanation:

The sample space refers to the set of all the possible outcomes.

The possible outcomes are:

Head and blue ball: BH

Head and green ball: GH

Head and yellow ball: YH

Head and orange ball: OH

Tail and blue ball: BT

Tail and green ball: GT

Tail and yellow ball: YT

Tail and orange ball: OT

The sample space is S= {BH,GH,YH,OH,BT,GT,YT,OT}

Answer:

Step-by-step explanation:

Isolate the term of t from one side of the equation.

First, you have to divide by 4 from both sides.

4t/4=40/4

Solve.

Divide the numbers from left to right.

40/4=10

First, change sides.

t+10=14

Then, subtract by 10 from both sides.

t+10-10=14-10

Solve.

Subtract the numbers from left to right.

14-10=4

First, subtract by 70 from both sides.

70-t-70=30-70

Solve.

30-70=-40

Rewrite the problem down.

-t=-40

Divide by -1 from both sides.

-t/-1=-40/-1

Solve.

Divide the numbers from left to right.

-40/-1=40

I hope this helps! Let me know if you have any questions.

Answer:

4t =40 t= 10  4x10=40

10 + t = 14 t=4   10 + 4 = 14

70 - t =30 t= 40  70 - 40 = 30

Hope this helps!

Answer:

The better deal will have the higher ratio of dollars per bagel.

To find the better deal, you must compare the fractions 8/7 and 6/9.

Comparng the fractions reveals that Betty has the better deal

Step-by-step explanation:

bobbs bagels: 8/7 equals 1.14, so each bagel would cost about $1.14

bettys bagels: 6/9 equals 0.66, so each bagel would cost about $0.66

$0.66 is better than $1.14 per bagel. therefore, bettys bagels are cheaper

hope this helps :)

Answer:

164

Step-by-step explanation:

Checkpoint 2= -187

Checkpoint 1= -23

The negatives mean how much lower they are from the surface.

To find "how much lower," we need to subtract -23 from -187.

-187-(-23) is the same as -187+23 (2 negatives=1 positive)

-187+23= -164.

However, it's not negative in the answer because by asking how much lower, we don't need to have a negative. "How much lower" is a distance, and a distance is always positive.

The overlap of data between both sets of data is low, hence the correct option is B. See below for more.

From the information provided, we can tell that two of nine samples for both populations correspond.

This results in a data-sharing of around 22%. This reading cannot be categorized as 'medium' because there isn't a lot of matching data.

It also but it's also 'none' because there is a non-negligible match. Hence the correct answer is C - Low.

Answer:

x=21

y=45

z=101

Step-by-step explanation:

Angles crossing each other are congruent

86=4x+2

84=4x

x=21

Quadrilateral has 360 degrees

86 + 86 + 2y+4 + z-7 = 360

172 + 2y+4 + z-7 = 360

2y+4=94

Answer:

So the whole thing is 180, we already have 3x+12, it's C.
Because A would be 3x +180 (1803x) +something else which would bring it over 180.

Step-by-step explanation:

C is the answer because 180 is the toal and it isn't going over 180 right away.

Answer:

C. (3x +12) + x = 180°

Step-by-step explanation:

(3z+12)° is obtuse. x° is acute.

Both are supplementary angles that are linear pair that add up to 180°

(3x + 12)° + x° = 180°

4x + 12 = 180°

4x = 168°

x = 42°

Plug x into (3x + 12)°

3*42° + 12

126 + 12

138°

Linear is basically a straight line. It can be increasing or decreasing.

Decreasing is when on the graph, when x increases, y decreases.

On the graph, there are two parts that are decreasing. Between -2 and 0, and Between 2 and 4. Let's look at these two.

- For between -2 and 0, the line is not straight. Therefore, it is decreasing and nonlinear. We can check if this is the right answer.

- For between 2 and 4, the line is decreasing. However, the line is straight, which means it is decreasing but linear.

Your final answer is B.
