Step-by-step explanation:

x - 4 = 0

=> x = 4

f(x)= 5x – 22x - 2x² – 25x +4

By remainder theorem,

f(4)= 5(4) – 22(4) - 2(4)² – 25(4) + 4

    = 20 - 88 - 32 - 100 + 4 ≠ 0

Since the remainder is not 0, x - 4 is not a factor.

Answer:

The answer is AAS.

Step-by-step explanation:

Since you have 2 angles that are the same and 1 side which are the same or congruent.

A = E

and C=C they are vertical angles so they are the same

And the AB and ED  side are also same.

[tex]\stackrel{\large{\frown}}{ADC} = 186^{\circ}[/tex]

Step-by-step explanation:

Given

See attachment

Required

Determine the measure of [tex]\stackrel{\large{\frown}}{ADC}[/tex]

[tex]The\ sum\ of\ angles\ in\ a\ circle\ is[/tex] [tex]360^{\circ}[/tex].

So, we have:

[tex]\stackrel{\large{\frown}}{ADC} + \stackrel{\large{\frown}}{APB} + \stackrel{\large{\frown}}{BPC} = 360^{\circ}[/tex]

Where:

[tex]\stackrel{\large{\frown}}{APB} = 70^{\circ}[/tex]

[tex]\stackrel{\large{\frown}}{BPC} = 104^{\circ}[/tex]

Substitute these values in the above equation.

[tex]\stackrel{\large{\frown}}{ADC} + 70^{\circ} +104^{\circ} = 360^{\circ}[/tex]

[tex]\stackrel{\large{\frown}}{ADC} + 174^{\circ} = 360^{\circ}[/tex]

Collect Like Terms:

[tex]\stackrel{\large{\frown}}{ADC} = 360^{\circ} - 174^{\circ}[/tex]

[tex]\stackrel{\large{\frown}}{ADC} = 186^{\circ}[/tex]

Answer:

186 is correct on khan academn=y

Answer:

Step-by-step explanation:

y = -4x + 7

perp. 1/4

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

y - 3 = 1/4x + 2

y = 1/4x + 5

The equation of the perpendicular line is y = 1/4x + 5

The equation is given as:

4x + y = 7

Make y the subject

y = -4x + 7

A linear equation is represented as:

y = mx + c

Where m represents the slope.

This means that:

m = -4

A line perpendicular to 4x + y = 7 will have a slope of:

Slope = -1/m

This gives

Slope = 1/4

The equation of the line is then calculated as:

y = Slope(x - x1) + y1

This gives

y = 1/4(x + 8) + 3

Expand

y = 1/4x + 2 + 3

Evaluate

y = 1/4x + 5

Hence, the equation of the perpendicular line is y = 1/4x + 5

Answer: 2(4)+2b=30  /missing lenght=11

Step-by-step explanation: We know the equation of a rectangle is 2a+2b=perimeter    "a" and "b" both represent a side length

2(4)+2b=30         <--- Plug in the know side lenght

8+2b=30            

8(-8)+2b=30(-8)  <--- Subtract "8" from both sides to further solve

2b=22

2b/2=22/2          <--- Divide each side by "2"

b=11

Answer:

y=2x+10

Step-by-step explanation:

In line equations its helpful to write your line in the form y = ax + b. This helps because a is always the gadient of the line and b is always the y intercept.

In this case it is y=2x+3

All parallel lines have the same gradient. The gradient of this line = 2.

If the line crosses the x axis at x=-5, then when x =-5 y = 0.

If you put all this in the form y =ax + b you get 0 = 2(-5) +b

So all you need to do to find b is rearrange. b = 10.

Therefore your line has gradient 2 and y intercept 10.

y = 2x + 10

Answer:

if x + 0 = 5, the value of x is 5.

Step-by-step explanation:

we discard 0 since it is of no value in the equation. thus, x = 5. i'm not sure if the one next to the plus sign is 0, since there's nothing there, but we'll assume it's 0. however, if it turns out to be another number, just transpose the other number next to 5 (it would be negative), and subtract. that will be your x.

Answer:

No, it does not.

Step-by-step explanation:

As if we attempted to solve for x, 5x & 5x will both cross each other out. There are no values of x that make the equation true.

Answer:

Step-by-step explanation:

In order for Forest to decide how many cans of paint to buy he first needs to know how many square feet make up the wall that he wants to paint. He can calculate this by multiplying the length of the wall by the height of the wall. That will give him the square footage of the wall which can be represented as x in the following formula. Now that he has that, he needs to divide this value by 150 which is what each can of paint covers. The answer will be the number of cans that Forest should buy.

x / 150 = number of cans

The numbers of cans of paint he should buy can be calculated as follows :

x / 150.

where

x = Area of the wall needed to be painted in square feet.

Forest needs to paint the right side of his house because of sunlight and

rain.

According to his analysis each can of paint will cover an area of 150 ft².

This simply means for every 150 square feet of his wall, he will require 1

can of paint.

The number of paint he should buy can be determined as follows:

let

x = area of the right side of his wall needed to be painted

The number of can required = x / 150

Answer: x=12

Step-by-step explanation: 10(x−3)=90

(10)(x)+(10)(−3)=90 (Distribute)

10x+−30=90

10x−30=90

Step 2: Add 30 to both sides.

10x−30+30=90+30

10x=120

Step 3: Divide both sides by 10.

x=12

Answer:

Perimeter of triangle PQR = 181.5 mm

Step-by-step explanation:

Midsegment theorem states that,

"Midsegment connecting the midpoints of the two sides of a triangle is parallel and half of the length of the third side"

From the figure attached,

PQ = [tex]\frac{1}{2}(EF)[/tex]

     = [tex]\frac{83}{2}[/tex]

     = 41.5 mm

PR = [tex]\frac{1}{2}(GF)[/tex]

     = [tex]\frac{110}{2}[/tex]

     = 55 mm

QR = [tex]\frac{1}{2}(GE)[/tex]

      = [tex]\frac{170}{2}[/tex]

      = 85 mm

Perimeter of triangle PQR = PQ + QR + PR

                                           = 41.5 + 55 + 85

                                           = 181.5 mm

Answer:

45.6° (1 d.p)

Step-by-step explanation:

Using the cosine rule;

c = √( a² + b² - 2ab Cosx)

11 =√(8² + 15² - 2 (8) (15) Cosx)

11² = 8² + 15² - 240 Cosx

11² - 8² - 15² = - 240 Cosx

-168 = -240 cosx

cosx = 0.7

x = cos⁻¹ (0.7) = 45.57 ≈ 45.6°
