Answer:

4 and -3

Step-by-step explanation:

2x+6=0

2x=-6

-3

x-4=0

x=4

So its 4 and -3

Answer:

-3,4

Step-by-step explanation:

(2x+6)(x-4) = 0

Using the Zero Factor Principle: If ab =0 then a=0 or b=0

2x+6=0 or X-4=0

solve 2x+6=0:

2x+6=0

Subtract 6 from both sides

2x+6-6 0-6

Simplify

2x = -6

Divide both sides by 2

2x/2 = -6/2

Simplify

X=-3

then x-4 =0

add 4 from to both sides

x=4

zeros : -3,4

(-3,0),(4,0)

A Taylor series approximation uses a Taylor series to represent a number as a polynomial that has a very similar value to the number in a neighborhood around a specified x value: f ( x ) = f ( a ) + f ′ ( a ) 1 ! ( x − a ) + f ′ ′ ( a ) 2 !

Answer:

  2 inches

Step-by-step explanation:

The area of the frame will be the difference between the area of the picture with frame, and the area of the picture without. We want that difference to be equal to the area of the picture without the frame.

Let x represent the width of the frame. The overall length and width of the picture will be increased by 2x when the frame is added. Then we have ...

  a = LW = (8+2x)(12+2x) . . . . area of picture and frame

  b = LW = (8)(12) . . . . . . . . . . area of picture

  a -b = b . . . . . . desired relationship between areas

Substituting and expanding the expressions for 'a' and 'b', we find ...

  a -2b = 0 . . . . subtract b

  (8 +2x)(12 +2x) -2(8)(12) = 0

  4x² +40x -96 = 0 . . . simplify

  x² +10x -24 = 0 . . . . . divide by 4

  (x -2)(x +12) = 0 . . . . factor

The positive value of x that makes this true is x = 2.

The width of the frame is 2 inches.

Answer:

x = 1

explanation:

[tex]\sf \rightarrow \dfrac{3}{x} -1 = 2[/tex]

[tex]\sf \rightarrow \dfrac{3}{x} = 2+1[/tex]

[tex]\sf \rightarrow \dfrac{3}{x} = 3[/tex]

[tex]\sf \rightarrow {3} = 3(x)[/tex]

[tex]\sf \rightarrow \dfrac{3}{3} = (x)[/tex]

[tex]\sf \rightarrow x = 1[/tex]

checking if x = 1,

[tex]\sf \rightarrow \dfrac{3}{1} -1 = 2[/tex]

[tex]\sf \rightarrow3 -1 = 2[/tex]

[tex]\sf \rightarrow 2 = 2[/tex]

→ Hence proved x : 1 as L.H.S = R.H.S

Step-by-step explanation:

[tex] \frac{3}{x} - 1 = 2 \\ [/tex]

[tex] \frac{3}{x} - 1 + 1 = 2 + 1 \\ \frac{3}{x} = 3[/tex]

[tex]3 \times x = 3 \times 1 \\ 3x = 3[/tex]

Dividing both sides by 3, we get

[tex] \frac{3x}{3} = \frac{3}{3} \\ x = 1[/tex]

Answer:

D. 33

Step-by-step explanation:

Triangle OSP is dilation of 1.5 of triangle NGQ, and side SP corresponds to side GQ.

22*1.5 = 33

Hope this helps :)

The interior angles of any triangle sum to 180° in measure, and in ∆ABC, the angles at vertices A and C are congruent. If we call their measure a, then

24° + 2a = 180°   ⇒   2a = 156°   ⇒   a = 78°

The angle at vertex C and the angle with measure (2x - 18)° are supplementary, meaning they add up to 180° :

a + (2x - 18)° = 180°

Solve for x :

78° + (2x - 18)° = 180°

(2x - 18)° = 102°

2x = 120

x = 60

1. Create a grid that is 5 squares wide by 2 squares tall. Shade 8 squares as shown above.

 A. Look at the shaded:total in the gizmo table. What decimal and percent are modeled by the shaded squares?

Decimal part =

10 squares

8 shaded

0.2=2 squares shaded

so

8 squares shaded = 0.8

Percent part =

if 100% = 1 whole

1 whole = 10 blocks in gizmo table

then

8 blocks in gizmo table = 80%

since

1 block = 10%

10%x8=80

80%

B. Look at the unshaded:total row. What decimal and percent by the unshaded squares?

Decimal part:

If there are 2 unshaded squares

and we know that 1 square = 0.1

then, 2 squares = 0.2

0.2

Percent part:

if we know that 10 blocks = 1 whole

and 1 block = 10%

then 2x10%=20%

20%

1. The Gizmo gives two equivalent (equal) fractions — simplified and unsimplified — for the shaded:total and unshaded:total ratios. Record them below. (to see why these are equivalent, notice how many shaded and unshaded squares are in each row of the grid.)

Answer:

x = 80.34 (2 dp)

Step-by-step explanation:

[tex]2\ln(x)+7=\ln(4x)+10[/tex]

[tex]\implies \ln(x^2)+7=\ln(4x)+10[/tex]

[tex]\implies \ln(x^2)-\ln(4x)=10-7[/tex]

Answer:

120 - 15% × 120 = x

Step-by-step explanation:

All given answers are incorrect.

15% means 0.15

She is not subtracting 15% or 0.15 from 120.

She is subtracting 15% of 120 from 120.

The correct answer is

120 - 15% × 120 = x

Answer:

Step-by-step explanation:he equation for circumference is:

c=2%28pi%29r

The equation for area is:

a=%28pi%29r%5E2

First, we'll find the circumference.

The 'r' in the equation stands for radius. The radius of a circle is half of its diameter, so the circle's radius is half of 6--3 inches.

So, we can substitute 3 in for 'r' and 3.14 in for pi

c=2%28pi%29r

c=2%2A3.14%2A3

Then, we can simply multiply.

c=2%2A3.14%2A3

c=18.84

Therefore, the circumference of the circle is 18.84

Next, we'll find the circle's area.

Again, we can substitute 3 in for 'r' and 3.14 in for pi

a=%28pi%29r%5E2

a=3.14%2A3%5E2

The, we'll square three and multiply.

a=3.14%2A3%5E2

a=3.14%2A9

a=28.26

Therefore, the circumference is 18.84 and the area is 28.26.

Step-by-step explanation:

There are 7 sections of equal size.

The total number of possible outcomes is 7.

There is one single outcome that is desired, landing on 7.

probability of an event = (number of desired outcomes)/(total number of possible outcomes)

p(7) = 1/7 = 0.142857... = 14%

ans = 9 degree

Step-by-step explanation:

81 + (4x) + (5x+18) = 180 (The sum of all angles of triangle is 180 degree)

81 + 4x + 5x + 18 = 180

99 + 9x = 180

9x = 180 - 99

9x = 81

x = [tex]\frac{81}{9}[/tex]
