please help me i really dont understand

Answer:

h(7) = 24

Step-by-step explanation:

Hi there !

h(a) = 3a + 3

replace a = 7

h(7) = 3×7 + 3

= 21 + 3

= 24

Good luck !

Answer:

4

Step-by-step explanation:

Lets make [tex]x[/tex] be the ? in the equation.

That becomes ([tex]x[/tex] x 3) - 3 = 15.

First you have to add 3 on both sides. After doing that it gets to ([tex]x[/tex] x 3) = 15 - 3.

Then you simplify it to 3[tex]x[/tex] = 12.

Now you divide 3 on both sides. That gets to [tex]x[/tex] = 4 after doing it.

Hope this helped! If not, please let me know! <3

its the second one

i had the question and the last one is wrong soo.....

If you found this helpful I would appreciate it if you thanked or liked.

Answer:

Step-by-step explanation:

Given the coordinates D(-2, 3), E(5, 5), F(-4, 10), to find the measure of the sides, we will use the formula for calculating the distance between 2 points as shown:

D = √(y2-y1)²+(x2-x1)²

For DE;

D(-2, 3), E(5, 5),

DE = √(5-3)²+(5-(-2))²

DE = √2)²+7²

DE = √4+49

DE = √53

For DF;

D(-2, 3), F(-4, 10)

DF = √(10-3)²+(-4-(-2))²

DF = √7²+(-2)²

DF = √49+4

DF = √53

For EF;

E(5, 5) F(-4, 10)

EF = √(10-5)²+(-4-5)²

EF = √5²+(-9)²

EF = √25+81

EF = √106

Since two he sides DE and DF are equal, this shows that the triangle is an isosceles triangle. An isosceles triangle  is a triangle that has two of its sides and angle equal

[tex]4+25=2+25[/tex]

They are equal because their sums both equal [tex]29[/tex].

Answer:

4 + 25 is equal to 4 + 25

Step-by-step explanation:

they are equal because both of the equations are the same so that would mean both of the equations would be equal to each other

hope this helps

Answer:

not very good

Step-by-step explanation:

the correlation should be almost 1  to be a good representation of the data. 0.82 isn't very close.  This would be a pretty "rough" approximation at best.  Maybe that's all that's needed but usually something close to 1.. like 0.99 is needed.

       -60 + 6 is -54

Answer: The robot can complete 10.5 tasks per a hour because 7 times 2/3 you do the keep change flip

Which well then equal 7 times 3/2 which will then equal 21/10 or 10 1/2 or 10.5

Answer:

They need more than 2.5 inches.

Step-by-step explanation:

average = 5.3

June: 6.3

July: 7.1

August: x

The average of the amounts for June, July, and August is

(6.3 + 7.1 + x)/3

To exceed the average, the average must be greater than 5.3.

(6.3 + 7.1 + x)/3 > 5.3

Multiply both sides by 3.

6.3 + 7.1 + x > 15.9

x + 13.4 > 15.9

Subtract 13.4 from both sides.

x > 2.5

Answer: They need more than 2.5 inches.

[tex]-7\sqrt{3}\pi[/tex]

Add similar elements

Answer:

A. [tex]-7\sqrt{3}\pi[/tex]

Step-by-step explanation:

To find the simplified form of that expression, we have to combine like terms. To do this, we should remember that:

ab + cb = (a + c)b

[tex]\pi\sqrt{3}-8\pi\sqrt{3}=(\pi-8\pi)\sqrt{3}=((1-8)\pi)\sqrt{3}=-7\pi\sqrt{3}=-7\sqrt{3}\pi[/tex]

So the simplified form would be [tex]-7\sqrt{3}\pi[/tex].

I hope you find my answer and explanation to be helpful. Happy studying.

Answer:

x+2

Step-by-step explanation:

====================================================

Explanation:

Angle BPO is congruent to angle POC because they are alternate interior angles and because AB is parallel to CD. So angle POC is 120+x degrees

This adds with angle COS to get 180

(angle POC) + (angle COS) = 180

(120+x) + (x) = 180

2x+120 = 180

2x = 180-120

2x = 60

x = 60/2

x = 30

angle COS = x = 30

angle POC = 120+x = 120+30 = 150

angle BPO = angle POC = 150

Answer:

[tex]first \: \\ x {}^{2} + x \\ = x(x + 1) \\ \\ second \\ {x}^{2} - 1 \\ = (x) {}^{2} - (1) { }^{2} \\ = (x + 1)(x - 1) \\ \\ third \\ x {}^{2} - x \\ = x(x - 1) \\ \\ therefore \: \: lcm = x(x + 1)(x - 1)[/tex]

Answer:

you good my guy

Step-by-step explanation:

Answer: 108 liters of gasoline is needed.

Hope this helps! :)

Given parameters:

Distance  = 140km

 Volume of gasoline  = 35liters

Unknown:

Volume of gasoline needed for 432km  = ?

Solution:

Let us first find the rate of gasoline consumption per mile. Using this value, we can then determine the volume of gasoline used for the distance given.

  Rate of gasoline consumption by the boat = [tex]\frac{volume of gasoline}{distance}[/tex]

                                                    = [tex]\frac{35}{140}[/tex]  

                                                    = 0.25liters/km

Now, the volume of gasoline needed for 432km;

   Volume of gasoline needed  = rate of gasoline consumption x distance

                                                    = 0.25 x 432

                                                    = 108liters of gasoline
