Answer:

600

Step-by-step explanation:

Area of Square:

= l*w

= 20x20 = 400

Area of Triangle:

= b*h/2

= 20*20/2

= 200

400 + 200 = 600

Good luck! <3

Answer:

The total area of the shape is 600 square centimetres.

Step-by-step explanation:

You can solve this by finding the area of the square and the triangle separately.

The area of any rectangle, including squares, is width times height. The bottom square then has an area of 20cm × 20cm, which equals 400cm²

The area of a triangle is have of its base width times its height.  It too has a width of 20cm and a height of 20cm, so its area is 20cm × 20cm ÷ 2, which equals 200cm²

Add them together for the full area of the shape:

400cm² + 200cm² = 600cm²

Answer: The answer would be 3z! Good luck!

Step-by-step explanation: Subract z from 4z, basically turn the equation to 4z - 1z, then put the variable (z) to the side and subtract 1 from 4. Once you're

done with that bring your variables back and you have 3z!

Answer:25 %

Step-by-step explanation:

Given

Last month count of chicken was [tex]20[/tex]

The current count of chicken is [tex]25[/tex]

The percentage increase is given by

[tex]\Rightarrow \dfrac{\text{Present value-Actual value}}{\text{Actual value}}\times 100[/tex]

Putting values

[tex]\Rightarrow \%=\dfrac{25-20}{20}\times 100=\dfrac{5}{20}\times 100\\\\\Rightarrow \%=25\%[/tex]

Answer:

19ft

Step-by-step explanation:

Given the height of a ball above the ground after x seconds given by the quadratic function y = -16x2 + 32x + 3, we can find the maximum height reached by the ball since we are not told what to look for.

The velocity of the ball is zero at maximum height and it is expressed as:

V(x) = dy/dx

V(x) = -32x+32

Since v(x) = 0

0 = -32x+32

32x = 32

x = 32/32

x = 1s

Get the height y

Recall that y = -16x² + 32x + 3.

Substitute x = 1

y = -16(1)²+32(1)+3

y = -16+32+3

y = -16+35

y = 19ft

Hence the maximum height reached by the ball is 19ft

Answer:

2/5 cups

Step-by-step explanation:

(3/4)*8=6

6/15= 2/5

Answer:

Values

1) a = 1, b = 3, c = -1

2) a = 2, b = -3, c = 6

3) a = 8 b = 1, c = -7

Step-by-step explanation:

To get the values, you need to write each equation in the format of ax²+bx+c=0, therefore you can find out each of the values easily. However for the third box, you aren't give the 'b' value in the equation, so you would have to assume that this is '1'.

To get the 'Answer', just simply input each of these values into the quadratic formula using a calculator.

The Quadratic formula:

[tex]x=\frac{ -b +- \sqrt{^{b} -4ac} \\}{2a}[/tex]

Use this and input all of the values required in each place, then simplify down if you don't have a calculator to find the answer.

Answer:

BC = 20 units

Step-by-step explanation:

if ∡C = ∡B then 2x + 16 = 7x + 6

16 = 5x + 6

10 = 5x

x = 2

BC = 2(2) + 16, which is 20

Answer:

okay so Y can be 6

and x can be 3

Step-by-step explanation:

so first 2*x=y

the most most likely answer will be y is 6 and x is 3 because

5*3=15

y=6

15-6=9

so x is 3 and y is 6

Answer:

If blue ribbon is 10 inches, red ribbon is 3 inches

If blue ribbon is 27 inches, red ribbon is 20 inches

If blue ribbon is x inches, red ribbon is x - 7 inches

Step-by-step explanation:

Given that,

Need to find,

--------------------------------------------------------------------------------------------------------------

How long is the red ribbon if the blue ribbon is 10 inches?

We know that the formula for find the length of the red ribbon is:

length of blue ribbon - 7 inches = length of red ribbon

Since we know the length of the blue ribbon (10 inches), we can apply that to the formula:

10 inches - 7 inches = length of red ribbon

So, what is 10 - 7? That gives us 3. So, the length of the red ribbon is 3 inches if the length of the blue ribbon is 10.

--------------------------------------------------------------------------------------------------------------

How long is the red ribbon if the blue ribbon is 27 inches?

We do the same as we did above to get 20 inches as the final answer because 27 inches - 7 inches gives us 20 inches as a difference.

--------------------------------------------------------------------------------------------------------------

How long is the red ribbon if the blue ribbon is x inches?

Since we do not know the value of x, we keep the length of the red ribbon to x - 7.

The length of the red ribbon is 3 inches if the blue ribbon is 10 inches.

The length of the red ribbon is 20 inches if the blue ribbon is 27 inches.

The length of the red ribbon is (X - 7) inches if the blue ribbon is X inches.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Length of blue ribbon = x

Length of red ribbon.

= x - 7

Now,

If x = 10
Length of red ribbon.

= 10 - 7

= 3 inches

If x = 27

Length of red ribbon.

= 27 - 7

= 20 inches

If x = X

Length of red ribbon.

= (X - 7) inches

Thus,

The length of the red ribbon is given above.

Answer:

(2x + 1) (x + 2)

Step-by-step explanation:

2x² + 4x + 1x + 2

They are already arranged, so you just have to find the GCF. 2x² + 4x  have the GCF of 2 and 1x + 2 have the GCF of 1.

2x (x + 2) + 1(x + 2)

Now you divide the whole thing by x + 2.

2x (x + 2) + 1(x + 2)/ x + 2

One of them cancels out  leaving (2x + 1) and (x+2)
