Answer:

D. 4+4k

Step-by-step explanation:

(12k +8) - (8+ 8k - 4)

12k +8 - 8 - 8k + 4

4k +4

d}4+4k

2(6k+4)-4(2+2k-1) writing down the question

12k+8-8-8k+4 multiplying the numbers by the coefficients

12k-8k+8-8+4 collecting like terms

4k+4 the answer

Answer: weight of wood part = 3.6 kilogram.

Step-by-step explanation:

Sculpture made of  both metal and wood = 14.4 kilogram

Weight of  metal=3/4 of 14.4 kilogram

which means the weight of metal = 3/4 x 14.4kg= 10.8kg

Since the rest is wood, we can say that

weight of wood = Total weight - weight of metal

= 14.4 kilogram-  10.8 kilogram= 3.6 kilogram

Answer i think 3.6

Step-by-step explanation:

The distance from the centre to any point on the circle is called the 'radius'. ... (i) Find the centre and radius of the circle (x-2)2+(y + 5)2 =9. ... Find the equation of the circle which has the line segment from a(-4, 3) to b(2, 1) as diameter. ... b and c. 22. Find the equation of the circle with centre (1, 3) and having the line 3x + 4y ...

Step-by-step explanation:

y = 4x - 7

Comparing the given equation with y = mx + c Then

slope (m) = 4

y -intercept (c) = - 7

Answer:

y-6 = -6(x-8)

Step-by-step explanation:

Here, we want to get the equation of the line in point-slope form

The point slope form is;

y-y1 = m(x-x1)

(x1,y1) represents the slope

We have this as ;

y-6 = -6(x-8)

Answer:x = 14

My Step-by-step explanation:

Turn the problem around by switching around the division:

238/x=17 means 238/17=x so x = 14.

Answer:

Let length of bc be x cm

Thus, ab=4x

ab+bc=ac

4x+x=75

5x=75

x=75/5

x=15

Therefore, ab=x=15cm

bc=4x=60cm

Answer:

2³ × 3² × 5

Step-by-step explanation:

360 = 2 × 2 × 2 × 3 × 3 × 5 = 2³ × 3² × 5

Answer:

formula

[tex]m = \frac{y2 - y1}{x2 - x1} [/tex]

Step-by-step explanation:

choose two point of A, let k(-2, -3) and l(1, 3)

[tex] m = \frac{ - 3 - 3}{ - 2 - 1} = \frac{ - 6}{ - 3} = \frac{1}{2} [/tex]

choose two point of B, let c(0, 5) and d(5, 0)

[tex]m = \frac{5 - 0}{0 - 5} = \frac{5}{ - 5} = - 1[/tex]

Hence the gradient of A is

[tex] \frac{1}{2} [/tex]

and B is -1

Step-by-step explanation:

Answer:

£600

Step-by-step explanation:

1/5 of 1000= £200

that means £800 is left over

ben gets £600, will gets £200

Answer:

Option c - 67.5

Step-by-step explanation:

Base= 15

Height = 9

Area= 1/2 x b h = 1/2 x 9 x 15 = 67.5 feet

Given:

Principal value = 40000

Rate of compounded interest = 20%

Time = 2 years

To find:

The interest.

Solution:

Formula for amount is

[tex]A=P\left(1+\dfrac{r}{100}\right)^t[/tex]

Where, P is principal, r is rate of interest and t is time in years.

Putting the given values, we get

[tex]A=40000\left(1+\dfrac{20}{100}\right)^2[/tex]

[tex]A=40000\left(1+\dfrac{1}{5}\right)^2[/tex]

[tex]A=40000\left(\dfrac{6}{5}\right)^2[/tex]

[tex]A=40000\left(\dfrac{36}{25}\right)[/tex]

[tex]A=57600[/tex]

Now, the formula for interest is

[tex]I=A-P[/tex]

[tex]I=57600-40000[/tex]

[tex]I=17600[/tex]

Therefore, the amount of compound interest is 17,600.

Answer:

x = [tex]942\frac{2}{9}[/tex]

Step-by-step explanation:

0.9 ( x - 20) = 830

0.9x - 18 = 830

0.9x = 848

9x = 8480

x = [tex]942\frac{2}{9}[/tex]

Answer:

Let's solve for x.

2x+3y=6

Step 1: Add -3y to both sides.

2x+3y+−3y=6+−3y

2x=−3y+6

Step 2: Divide both sides by 2.

2x 2 =

−3y+6

2 x= −3

2 y+3

Answer:

x= −3 2

Answer:

-0.8(x + 9)(x - 1)

Step-by-step explanation:

Note that 0.8 is a factor of the three coefficients -0.8, -6.4 and 7.2.  Thus,

-0.8x2 - 6.4x + 7.2  =  0.8(-1x^2 - 8x + 9), or, equivalently,

                               = -0.8(x^2 + 8x - 9), which factors further as follows:

                                = -0.8(x + 9)(x - 1)

Step-by-step explanation:

(x+20)=9x

4x=20

x= 5°

because GEF AND DEG ARE EQUAL

THEN DEF= 2 * GEF

DEF = (9*5)*2=90

DEF= 90°

Answer:

x=9

Step-by-step explanation:

I basically just used the bottom left corner and since all of them are 90 degrees, i did 90-18 then i got 72 and i just divided it by 8 and got 9.
