Can someone help ASAP please?

Answer:

Step-by-step explanation:

if we are supposed to solve [tex]x^{2}[/tex] + 2x + 9 = 0   there here is the solution

using the quadratic formula

= (-2 ± [tex]\sqrt{2^{2}-4*9 }[/tex] )/2

= (-2 ± [tex]\sqrt{-32}[/tex]) / 2

= (-2 ± i [tex]\sqrt{16*2}[/tex])/2

= (-2 ± i 4[tex]\sqrt{2}[/tex])/2

= -1 ± i 2[tex]\sqrt{2}[/tex]

Answer:

80 pages

Step-by-step explanation:

Let the required length of paper = x

Hence:

80% of x = 64 pages

80/100 × x = 64 pages

80x /100 = 64 pages

Cross Multiply

80x = 100 × 64 pages

x = 6400/80

x = 80 pages

Therefore, the required length of the paper = 80 pages

Answer:

2. y=9x

3. 180*9 = 1620

Step-by-step explanation:

2. y = mx+b, so find the slop efirst

lacampanella avatar

so take the first two points you got

lacampanella avatar

(2,18) and (5,45),

lacampanella avatar

(45-18)/(5-2) = 9

lacampanella avatar

then use (2,18)

lacampanella avatar

18= 9*2+b

lacampanella avatar

so b=0

3. y = 9x

x= 180. y = 9*180 = 1620

Answer: x= -7

Explanation for answer:

Answer:

x = -7

Step-by-step explanation:

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other.

First, add 2x and subtract 18 from both sides:

5x - x + 18 (-18) (+2x) = 6 - 2x (+2x) - 30 (-18)

5x - x + 2x = 6 - 30 - 18

Next, simplify. Combine like terms:

(5x - x) + 2x = 6 + (-30 - 18)

(4x) + 2x = 6 + (-48)

6x = -42

Next, fully isolate the variable, x, by dividing 6 from both sides:

(6x)/6 = (-42)/6

x = -42/6 = -7

x = -7 is your answer.

Answer : The angles are vertical angles and the value of x is [tex]25^o[/tex]

Step-by-step explanation :

Adjacent angles : It is defined as the two angles that have the common arm and common vertex.

Vertical angles : It is defined as the two lines intersect each other and form angles. The opposite angles are known as vertically opposite angles.

And we know that the vertically opposite angles are equal.

In the given image, the angles are vertical angles and vertically opposite angles are equal.

So,

[tex](4x-25)^o=75^o[/tex]

[tex]4x-25^o=75^o[/tex]

[tex]4x=75^o+25^o[/tex]

[tex]4x=100^o[/tex]

[tex]x=\frac{100^o}{4}[/tex]

[tex]x=25^o[/tex]

Therefore, the angles are vertical angles and the value of x is [tex]25^o[/tex]

Answer:

x = [tex]\sqrt{3}[/tex]/6

Step-by-step explanation:

30-60-90 triangles have legs in the ratio of 1 : [tex]\sqrt{3}[/tex] : 2

create a proportion:  (6 ÷[tex]\sqrt{3}[/tex]) = (1÷x)

cross-multiply:  6x = [tex]\sqrt{3}[/tex]

Plug in the numbers: 3≤3-2(0)

3≤3-0

3≤3

Step-by-step explanation:

it's rule is multiplying the in by 3

2 *3 = 6

4 * 3 = 12

7 * 3 = 21

9 * 3 = 27

Answer:

times 3

Step-by-step explanation:

ok so this is how I do it, I recommend it!

Look out the out number in the first number: 6

Ask yourself how to get from 6 to 2???......divided by 3 ofc!

Ok so then we see 4 and we multiply by 3=12

21 divided by 3 is 7! Rule right again!

27 divided by 3 is 9! Yay we did it!

Hope this helps :>

Step-by-step explanation:

Answer:

angle x = 98

angle y = 82

angle z = 82

Step-by-step explanation:

angle y + 98 = 180; therefore, angle y = 82 degrees

angles z and y are alternate interior angles and are congruent (equal)

angle x is 98 degrees because angles x and y are same-side interior and their angles are supplementary (add up to 180 degrees)

Step-by-step explanation:

Answer:

$4.04

Step-by-step explanation:

Since the ice cream is 15% off, that means you will have to subtract 0.15 from 1, since 1 is 100%, and 0.15 is 15%. If you do the math, then you will get 0.85, which translates to 85%. So now that we have found the percentage of the original price that we have to pay, we can do some more advanced calculations. Since we found the 1 - 0.15 = 0.85, we will multiply the original price, which is $4.75, by 0.85. You can do this by hand or by calculator. You will get 4.0375, which is your answer. Since this is about money, you will have to add a $ sign at the beginning, which would be $4.0375. Of course, you can't pay a percentage of a cent, so you would have to round that up to $4.04. In conclusion, the sale price of the half-gallon of ice cream is $4.04.

Answer:

  24 cm^2

Step-by-step explanation:

The larger rectangle has dimensions in cm of 12 by (4+x). The smaller rectangle has dimensions of (x+2) by x. The area of the larger is 4 times the smaller, so ...

  12(4+x) = 4(x)(x+2)

  3(4+x) = x(x+2) . . . . . . divide by 4

  x^2 +2x -3x -12 = 0 . . . eliminate parentheses, subtract 3(4+x)

  (x -4)(x +3) = 0 . . . . . . . factor

The positive solution is x = 4, so the area of the smaller rectangle is ...

  x(x+2) = 4(4+2) = 24 . . . cm^2

Answer:

The answer is A. 25 ft

Step-by-step explanation:

Given a=24 and b=7,

c = 25

∠α = 73.74° = 73°44'23" = 1.287 rad

∠β = 16.26° = 16°15'37" = 0.28379 rad

h = 6.72

area = 84

perimeter = 56

inradius = 3

circumradius = 12.5
