Students planted 2(3x + 4y) amount of trees on Saturday and then 3(x + 8) amount of trees on Sunday. What is the total amount of trees that the students planted? *

Answer:

12 [tex]units^{2}[/tex]

Step-by-step explanation:

All you have to do is do each shape then add them all up

small triangle:

a = b * h/2

a = 2 * 2/2

a = 4/2

a = 2

The area for the small triangle is 2

Sqaure:

a = b*h

a = 2*2

a = 4

The area for the sqaure is 4

Large triangle:

a = b*h/2

a = 6*2/2

a = 12/2

a = 6

The area for the larger square is 6

Now we add up all of the areas

2 + 4 + 6 = 12

The area for that shape is 12 [tex]units^{2}[/tex]

Hint: We divide by 2 for the triangles bc it's half a shape not a full rectangle of square...

Hope this helped!

Answer:

3^4, or you could say three to the fourth power.

An exponent is a quantity representing the power to which a given number or expression is to be raised, usually expressed as a raised symbol beside the number or expression. 3 x 3 x 3 x 3 is equivalent to 3^4 because you are multiplying three four times.

*Warning: 3 x 3 x 3 x 3 is NOT 3 x 4!!!*

Answer:

x=-2

Step-by-step explanation:

Let's solve your equation step-by-step.

3x+9=x+5

Step 1: Subtract x from both sides.

3x+9−x=x+5−x

2x+9=5

Step 2: Subtract 9 from both sides.

2x+9−9=5−9

2x=−4

Step 3: Divide both sides by 2.

2x /2=-4/2

x=−2

Answer:

I'm pretty sure the answer is the last one;

6 x (40+2) = (6 x 40) + (6 x 2)

The 6 is distributed to the 40 and the 2

Answer:

31

Step-by-step explanation:

Answer:

47

Step-by-step explanation:

The cost of beginner classes is $7.6 and the cost of the advanced classes is $29.2

Addition, subtraction, multiplication, and division are the four basic algebraic operations.

Given that, x is the cost of beginner classes, and y is the cost of advanced classes.

The relationship between beginner classes and advanced classes is

x=0.5y-7

4x+3y=118

From the first equation, we can write

y=2x+14

Using this equation, we can write

4x+3(2x+14) =118

10x+42=118

i.e x=7.6

Substituting the value of x in the equation y=2x+14, we get

y=(2*7.6)+14

i.e y=29.2

The cost of beginner classes is $7.6, and the cost of advanced classes is $29.2.

Answer:

Step-by-step explanation:

Circumference = 2nr

C = 2 x 3.14 x 5

C = 31.4

A = nr^2

A = 3.14 x 5^2

A= 3.15 x 25

A = 78.5

Answer: x = 12

Step-by-step explanation:

5(x-1)+3x=7(x+1)

5x - 5 + 3x = 7x + 7

8x - 5 = 7x + 7

x - 5 = 7

x = 12

Answer:

1/125

Step-by-step explanation:

(1/5)³ = 1/125

1³ = 1

5³ = 125

Answer:

Step-by-step explanation:

this looks like  1/5 * 1/5 * 1/5

multiply the tops ( numerators) and the bottoms (denominators)

tops are 1

bottoms are 125

Answer:

The relation [tex]y^{2} - 4x = 3[/tex] does not represent y as a function of x.

Step-by-step explanation:

Consider the relation

[tex]y^{2} - 4x = 3[/tex]

[tex]y=\pm \sqrt{4x+3}[/tex]

Thus, the equation [tex]y=\pm \sqrt{4x+3}[/tex] does not represent function because there is at least one x-value with two or more values.

For example, if you look at the attached graph,

at x = 0, y = 1.73

at x = 0 , y = -1.73

It means the same input is generating two outputs; also if we draw a vertical line on the graph, the vertical line would intersect the graph more than once.

Please check the red vertical line on the graph would intersect the graph more than once.

Therefore, the relation [tex]y^{2} - 4x = 3[/tex] does not represent y as a function of x.

Answer:

option d x^2 + 8x

Step-by-step explanation:

area of rectangle = l×b

=x×(x+8)

=x^2+8x

The Pythagoras Theorem:

the base squared and height squared added is equal to the hypotenuse squared.

so

(x+6)² + (x+3)²= (x+9)²

x²+36+12x+x²+9+6x = (x+9)²

2x²+45+18x=x²+81+18x

x²=36

x=√36

X= 6

now

(x+6)= 12

(x+3)=9

(x+9)=15
