plsssssssssssssss help me nobody knows how to do it and its due tonight

Answer:

(x - 15) ( x + 3)

Step-by-step explanation:

x² - 12x - 45

= x² - (15 - 3)x - 45

= x² - 15x + 3x - 45

= x(x - 15) + 3(x - 15)

= (x - 15) ( x + 3)

Step-by-step explanation:

Answer:

100 inches

Step-by-step explanation:

Given that the mans height is 71 inches. Height of lamp is 108 inches and distance between them is 52 inches. For Figure refer to attachment . The given figure both triangles are similar by AA similarity Condition. So we know that the corresponding parts of similar triangles are proportional .Let Distance between man a d its shadow be x .

Using this concept ,

=> AM / PN = QA / QP

=> 108 / 71 = 52 + x / x

=> 1.52 x = 52 + x

=> 1.52 x - x = 52

=> 0.52 x = 52

=> x = 52/0.52

=> x = 100 in .

Answer:

[tex]\£3840.2[/tex]

Step-by-step explanation:

Let P denotes principal amount, T denotes time period and R denotes rate of interest.

Amount = [tex]P(1+\frac{R}{100})^T[/tex]

Amir pits £3035 into a bank account. The account pays 4% compound interest each year.

Put [tex]P=\£3035,\,R=4\%,\,T=6[/tex]

Amount = [tex]3035(1+\frac{4}{100})^6=3035(\frac{104}{100})^6=\£3840.2[/tex]

Therefore, Amir will have [tex]\£3840.2[/tex] in the account after 6 years.

Answer:

m = 4

Step-by-step explanation:

Points on the graph: ( -3, -3) and ( -2, 1)

Slope:

m=(y2-y1)/(x2-x1)

m=(1+3)/(-2+3)

m=4/1

m = 4

Step-by-step explanation:

3x+12=2x+2x

3x+12=4x

3x-4x=-12

-x=-12

x=12

Answer:

no, the answer is x = 12

Step-by-step explanation:

3(x + 4)= 2x - (-2x)

3(x + 4)= 2x + 2x

3x + 12 - 12 = 4x - 12

3x - 4x = 4x - 12 - 4x

-x = -12

x = 12

Answer:

100 minutes

Step-by-step explanation:

This is because it takes 5 minutes to fry 24 wantons, so we can write 5/24. Now we need to find out how long it takes to fry 40 dozen wantons, or 480 wantons. We can rewrite this as x/480. Since the time should be proportional, we get the following:

5/24 = x/480

We can now cross multiply. 24x=5x480. Therefore, 24x = 2400. If we divided each side by 24, we would get 100. Therefore, it takes 100 minutes to fry 40 dozen wantons, or about 1  2/3 hours.

Answer:

100 minutes (1 hour & 40 minutes).

Step-by-step explanation:

5 minutes = 2 dozen, which means it takes 2.5 minutes to cook 1 dozen.

2.5 minutes x 40 dozen = 100 minutes...

Answer:

4 ounces

Step-by-step explanation:

the measurement of water and the bottle are in different units. This, they have to be converted to the same units

1 cup = 8 ounces

if the bottle holds one cup, it would hold 8 ounces

ounces of water left over = 12 - 8 = 4 ounces

Answer:

Simple: C. 70% = Rs. 84

Step-by-step explanation:

cause it can't be 120% if Rs.120 is the 100%

Answer:

Step-by-step explanation:

Notice that the difference is in the y-intercept.  The first equation has a y-intercept of 0 since y = 4x + 0, the second has a y-intercept of 1 since

y = 4x + 1.  In other words, the graph is translated up 1 unit to cross at (0,1) instead of (0,0)

Answer:

$19.2

Hope this helps!! :)

Answer:

$19.20

Step-by-step explanation:

First find how much 20% of 24 is.

What is 20% of 24?

Y is 20% of 24

Equation: Y = P% * X

Solving our equation for Y

Y = P% * X

Y = 20% * 24

Converting percent to decimal:

p = 20%/100 = 0.2

Y = 0.2 * 24

Y = 4.8

Then subtract that from $24

Which gives you $19.2

because at that point is where the line crosses the y axis.

Answer:

64 - .75

64 - .75 = 63.25

have a good day/night

Answer: 63.25 (Decimal) or 63 1/4 (fraction)

Step-by-step explanation: 64 - 3/4. 3/4 is 0.75 in decimal form, so subtracting it would be 63.25 which would be 63 1/4 in fraction form. I don’t think you can simplify it since 1/4 is already at it’s smallest form.

Answer:

x = 7; y = 77

Step-by-step explanation:

y = 9x + 14

y = 4x + 49

Since both equations are solved for y, set the two right sides equal and solve for x.

9x + 14 = 4x + 49

5x = 35

x = 7

Sow substitute 7 for x in the first equation and solve for y.

y = 9x + 14

y = 9(7) + 14

y = 63 + 14

y = 77

Answer: x = 7; y = 77

Answer:

x=7 y=77

Step-by-step explanation:

Subtract 4x from 9x you get 5x

subtract 14 from 49 you get 35

5x=35

9*7=63+14=77

4*7=28+49=77

Answer:C

Step-by-step explanation:

Answer:

y=11x-18

Step-by-step explanation:

y=11x+b (b is the unknown y-int)

to find the y-int, substitute in (2, 4), and solve for b *substitute in 2 for x and 4 for y*

y=11x+b

4=11(2)+b

4=22+b

b=-18

the equation of the line:

y=11x-18

Answer: 84.8°

Step-by-step explanation:

a²+b²+c²-2bc(cosA)

cosA = b² + c² - a² / 2bc

That is the formula we will be using.

Then, plug in our numbers.

cosP= 500² + 380² - 600² / 2(500)(380)

cosP= 34400/380000

cosP≈ 0.09052631

cos⁻¹(0.09052631) ≈ 84.81

∠P = 84.8°
