(2x-1)(3x-1) in quadratic expression standard form

Answer:

that would be 0 lines for symmetry

Answer:

B

Step-by-step explanation:

A parallelogram has no line of symmetry but has rotational symmetry of order 2

Answer: AB=21.88 mm, BC=51.54 mm

Step-by-step explanation:

Given

[tex]\angle A=67^{\circ}[/tex]

[tex]AC=56\ mm[/tex]

The other two sides can find out using trigonometry

[tex]\Rightarrow \sin 67^{\circ}=\dfrac{BC}{AC}\\\\\Rightarrow \sin 67^{\circ}=\dfrac{BC}{56}\\\\\Rightarrow BC=56\sin 67^{\circ}\\\Rightarrow BC=51.54\ mm[/tex]

Similarly, for AB

[tex]\Rightarrow \cos 67^{\circ}=\dfrac{AB}{AC}\\\\\Rightarrow \cos 67^{\circ}=\dfrac{AB}{56}\\\\\Rightarrow AB=56\cos 67^{\circ}\\\Rightarrow AB=21.88\ mm[/tex]

Angle C is given by

[tex]\angle C=90^{\circ}-67^{\circ}\\\angle C=23^{\circ}[/tex]

Should I simplify? Get  the factor? Multiply? Evaluate? Can you tell me?

Answer:

k=9 is the answer

Add 6 on each side then gives you 2k=18

then 2 divided by 18 is 9

Answer:

1/4 ; 3/8

Step-by-step explanation:

Probability of landing on 2 :

Required outcome = Number of 2's on spinner = 2

Total possible outcomes = Number of congruent spaces on spinner = 8

P(landing on a 2) = 2 / 8 = 1/4

Probability of landing on 1 :

Required outcome = Number of 1's on spinner = 3

Total possible outcomes = Number of congruent spaces on spinner = 8

P(landing on a 1) = 3 / 8

Landing in each section of the spinner is equally likely to occur as the spinner are divided into congruent spaces. However, landing on the labels of the spinner isn't equally likely as each label take up uneven number of congruent spaces on the spinner.

Step-by-step explanation:

Answer:

C) 3/5

Step-by-step explanation:

Have you heard of this way to memorize the trig ratios?

SOH-CAH-TOA  (Say it out loud so you remember it.)

It represents these ratios:

Sine = opposite side / hypotenuse

Cosine = adjacent side / hypotenuse

Tangent = opposite side / adjacent side

In this problem, cos C = adj / hyp = BC / AC = 24 / 40.

That simplifies to 3/5

i used a²+b² = c²

option (D) 28 √6 is the answer

Explanation :

p =3√6 + 2√24 + 7√54

3√6 + 2√2×2×6+ 7√3×3×6

3√6 +2 ×2√6 + 7 ×3√6

3√6 +4√6 + 21√6

28√6

Answer:

90

Step-by-step explanation:

First you do s^2. In this case s is 3 and 3x3=9. Then multiple 9 by r. 9x2=18. Finally, multiply 18 by t. 18x5=90. The solution is 90

Step-by-step explanation:

4.5(9+d)-6

6.3h-j

8.r(s)²(t)

Answer:

13, 21

Step-by-step explanation:

d = (29 - 5)/3

d = 8

5 + 8 = 13

13 - 8 = 21

Answer:

37. 0 triangles

38. 1 triangle

39. Yes

40. 13 or greater

Step-by-step explanation:

According to the triangle inequality theorem, the sum of the side lengths of any 2 sides of a triangle must exceed the length of the third side, so since 5 + 8 = 13, the third side must not be 13 or greater.

Answer:

2 cm

Step-by-step explanation:

Given that

The length is 13 cm longer than its width

And, the volume of the box is 60cm^3

We need to find out the dimension of the box

Since the box has square ends

So,

the height is equivalent to the width

Let us assume the width be W so the height also be W

Now the length is W + 13

The volume is

W × W × (W + 13) = 60

After solving this W is 2 cm

Answer:

answer: 20

Step-by-step explanation:

To find the area of a parellologram you just have to do base × height are base here is 10 and our height is 2 so 10 × 2 = 20 So 20 is the area! Hope that helps/explains well!

Answer:

the volume of the cut-out is 200 cm³

Step-by-step explanation:

Given;

length of each side of the square cardboard, L = 10 cm

the thickness of the cardboard, h = 2 cm

The volume of the cut-out = area of the square cardboard  x  thickness of the cardboard

The volume of the cut-out = L² x h

The volume of the cut-out = 10 cm x 10 cm x 2 cm

The volume of the cut-out = 200 cm³

Therefore, the volume of the cut-out is 200 cm³

Answer:

-335

Step-by-step explanation
