Answer:

b. 4m

Step-by-step explanation:

congruent polygons means same shape, size, angles, and sides.

Answer:

63 degrees

Step-by-step explanation:

Since this is an isosceles triangle, the two bottom angles must be equal, while the top angle (in the way this specific triangle is oriented) must be different. Therefore, angle CDB is 63 degrees.

Answer:

∠CDB = 63°

Step-by-step explanation:

∠CBD and ∠CDB opposite side lengths are congruent (indicated by the little markings)

Because their opposite sides are congruent they are too congruent

So ∠CBD = ∠CDB

because ∠CBD = 63° ∠CDB also equal 63°

Answer:

Step-by-step explanation:I belive that the 7x+22 needs to equal 50 because they opposite angles. Hope this helped a little and can get you started

Answer:

22.57

Step-by-step explanation:

7x+ 22 =180 180 because its a supplimentary angle -22 from 22 and 180 22 and -22 cancel out the 180 - 22 = 158

then you have 7x = 158     divide both numbers by 7 to isolate x then divide 158 by 7 = 22.57

Answer:

1. 18

2. 5

3. 8

4. 6

5.-12

Step-by-step explanation:

im not really sure how to explain it to you but the first one that were positive numbers you can just subtract them and get the answer which i gave the forst five to you and when you are this is just an example of the adding the negative numbers 4. -15 + n = -9 you can subtract it and you'll get -15 - (-9) = -6

but if you put negative six it's gonna be the wrong answer sooo you just switch it to a positive number 6 because if you put -15 + (-6) = -21 and when its like this -15 + n = -9 the answer is smaller that the bigger number sooo the only right thing to do it put the positive 6

i hope i got you understanding it a little more if i didnt im soory i tried but the 5 answers i gave you correct

Answer:

3

Step-by-step explanation:

f(x)=5x-7

for f(2) just put 2 in place of x

so,

f(2)=5(2)-7

f(2)=10-7

f(2)=3

Step-by-step explanation:

these are the answers of your questions

Answer #1:

x ( 3 x − 4 ) ²

Answer:

1) Area = ½ b × h

= ½ × 6 × 4

= 12

2) Area = ½b × h

= ½ × 3 × 4

= 6

3) Area = ½b × h

= ½ × 4 × 7

= 14

Solution :

Given :

[tex]$f(x)=x^3-x^2-18x+19$[/tex]

By using the remainder theorem, if f(x) is divided by (x-k) and the remainder is 'r', then

[tex]$f(x)=(x-k)q(x)+r$[/tex]

Here, k = 4

Therefore, divide the f(x) with (x - 4) to find the q(x) and r.

Answer:

(8 + 4 × 6) ÷ 2 + 7

Step-by-step explanation:

8 + (4 × 6) ÷ 2 + 7 = 27

8 + 24 ÷ 2 + 7

8 + 12 + 7

27

8 + 4 × 6 ÷ (2 + 7) = [tex]10\frac{2}{3}[/tex]

8 + 4 × 6 ÷ 9

8 + 24 ÷ 9

[tex]8 + 2\frac{2}{3}[/tex]

[tex]10\frac{2}{3}[/tex]

(8 + 4 × 6) ÷ 2 + 7 = 23

(8 + 24) ÷ 2 + 7

32 ÷ 2 + 7

x = 3

Answer: 4 hours

Step-by-step explanation:

Given

Auto charge a fixed amount of $35

and $7 per hour

Rafa bill was $63

Suppose Rafa travels for x hours. So, we can write

[tex]\Rightarrow 63=35+7x\\\Rightarrow 28=7x\\\Rightarrow x=4\ \text{hour}[/tex]

Answer:

Step-by-step explanation:

Assuming the parking lot is along both widths of the field and only once along the length:

the length is (300 - 2x)

the width is (200 -x)

the area is (300-2x)(200-x) = 30000

         60000 -300x - 400x +2x^2 = 30000

        2x^2 -700x + 30000 = 0

         x^2 - 350x + 15000 = 0

          (x    -   300    )(x   -    50    ) = 0

             x = 300 or x=50

x=300 results in negative measures.

the parking lot is x=50 wide

the length of the field is 200, the width of the field is 150

Given:

Length of the building  = 120 feet

Width of the building = 40 feet

Length of the model = 6 feet

To find:

Width of the model.

Solution:

The scale model similar to the original figure and the corresponding sides of the similar figures are proportional.

Let x be the width of the building.

[tex]\dfrac{\text{Length of the building}}{\text{Length of the model}}=\dfrac{\text{Width of the building}}{\text{Width of the model}}[/tex]

[tex]\dfrac{120}{6}=\dfrac{40}{x}[/tex]

[tex]20=\dfrac{40}{x}[/tex]

[tex]x=\dfrac{40}{20}[/tex]

[tex]x=2[/tex]

Therefore, the width of the model is 2 feet.

Answer: vertical & x = 25

75 = 4x - 25

100 = 4x

x = 25
