Answer:

THis man confused yall the answr id D

Step-by-step explanation:

The shape which is congruent to the given shape is shape D.

Congruent figures are defined as the figures which are exact copies of each other.

That is, the dimensions and angles are equal.

Here given a shape which is in the shape of a parallelogram.

Options A and C are not congruent figures since they are not even a parallelogram.

Option B is a parallelogram which can be clearly seen that there is more width.

Option E is also not the one since it is smaller in size.

The congruent figure is thus, option D.

Hence the correct option is D.

The complete question is given below.

Answer:

2z(2z+1)

Step-by-step explanation:

Write the equation for the area and then factor the polynomial to find the possible expression for the length and width.

A = 4z2 + 2z The GCF of 4z2 and 2z is 2z.

= 2z(2z) + 2z(1) Write the terms as products using the GCF as a factor.

= 2z(2z + 1) Use the distributive property to factor out the GCF. Possible expressions for the dimensions of the wall are 2z m and (2z + 1) m.

The requried expression of the length and width is (2z + 1) and 2z.

A number or algebraic expression that evenly divides another number or expression—i.e., leaves no remainder—is referred to as a factor.

Here,
As mentioned in the question, the amount of paint needed to cover a wall is proportional to its area.

The wall is rectangular and has an area of 4z² + 2z square meters. According to the question, we have factored this polynomial to find possible expressions for the length and width of the wall.
So,
Area =  4z² + 2z

Takin common 2z
Area = 2z × (2z + 1)

Comparing the above expression with
Area of rectangle = width × length

From comparison,

Length = (2z + 1)
Width = 2z

Thus, the requried expression of the length and width is (2z + 1) and 2z.

Answer:

(xy) (xy) (1−1) (2 3)

Step-by-step explanation:

Slope 4 intercept is -5 we can rearrange with 4x-y=5

We then work out y= -5+ 4x  and y=4x−5

We know there is a 4 intercept and we are ready in negatives -5

The slope goes up again by 4 after -1

4+-1 = 3 to find y

We find x by plugging in these values 3(-1) = 2

The required solution as ordered pairs to the given equation 4x - y = 5 are (5/4,0) and (0,-5)

A linear equation is defined as an equation in which the highest power of the variable is always one.

The equation is given in the question

4x - y = 5  ....(i)

We have to determine the ordered pair (x, y) that is a solution to the given equation.

Two that to find are (a,0) and (0,b); these points are/contain the x and y intercepts.

Substitute the point coordinate values for x and y in the equation and solve for the remaining variable.

Substituting into the given equation (i):

(a,0): 4a - 0 = 5 ⇒ a = 5/4 and (a,0) = (5/4,0)

(0,b): 4(0) - b = 5 ⇒ b = -5 and (0,b) = (0,-5)

Therefore, the required solution as ordered pairs to the given equation 4x - y = 5 are (5/4,0) and (0,-5)

[tex]x=-\frac{3\sqrt{2}-3 }{2}[/tex]

Step-by-step explanation:

Open the brackets first:

[tex]4x^2+9=18-12x[/tex]

Simplify:

[tex]4x^2+12x-9=0[/tex]

It is determined that this can't be factored, so rewrite the equation so you can complete the square.

[tex]x^2+3x=\frac{9}{4}[/tex]

Take the square of 1.5 and add it to both sides:

[tex]x^2 + 3x+ \frac{9}{4} =\frac{9}4} +\frac{9}{4}[/tex]

Factor:

[tex](x+\frac{3}{2})^2=\frac{9}{2}[/tex]

[tex]x+\frac{3}{2} = \frac{3\sqrt{2} }{2 }[/tex]

or [tex]x+\frac{3}{2} =-\frac{3\sqrt{2} }{2}[/tex]

So [tex]x=\frac{3\sqrt{2}-3 }{2}[/tex]

Answer:

x= 4/9

Step-by-step explanation:

-1/(2x) + 1/8 = -1/(3x) - 1/4

-1/(2x)+1(3x)= - 1/4 -1/8

-3/(6x)+2(6x) = -2/8 -1/8

- 1/(6x) = - 3/8

-1*8 = -3*6x

8=18x

x= 8/18= 4/9

Check:

-1/(2*4/9) + 1/8 = -1/(3*4/9) - 1/4

- 1(8/9) + 1/8 = - 1/(4/3)-1/4

-9/8+1/8 = - 3/4-1/4

-1 = -1

Answer: 44%

Step-by-step explanation: First, let's add up all the children in the classroom...

15 + 12 = 27

There's 15 boys, therefore have to divide 15 by 27...

15 ÷ 27 = 0.55 x 100 = 55%

Now, let's divided the total amount of girls...

12 ÷ 27 = 0.44 x 100 = 44%

44 + 55 = 99%

The perecent of girls in the classroom are 44%, I hope this helps!

Answer:

x = 4 and y = 1

Step-by-step explanation:

3x+2y=14

2x-4y=4

We can solve them by canceling out one variable so we only have one variable left. Let's cancel out y by doubling the first equation. We get:

6x + 4y = 28

add that on to the second one and we get:

8x = 32

x = 4

We plug in x and get that:

y = 1

So in the end we get

x = 4 and y = 1

Answer:

Step-by-step explanation:

We know that "bending" means to force or shape something into a curve or certain angle.

Now, when we bend something we are actually using a pair of forces, not just one, because you can't bend using only one forces, that would imply using one hand which is impossible. Notice that you need to forces to be applied at different points in the same direction to create the curve, these forces must be applied a certain distance away from the equilibrium point which is between the points of application.

Therefore, there are two forces involves because we need to use two points of application to bend something.
