Please help me I don’t understand this at all and I need to pass quits so please somebody out there help me

(x-8)(x+4)+(x-3)(x+9)

Remove parenthesis.

x-8+x+4+x-3+x+9

Then rearrange.

x+x+x+x+4+9-8-3

Now add/subtract.

4x+13-11

We still have combining to do...

4x+2

That's as far as it goes

Answer:

[tex]tan(30) = \frac{A}{B}[/tex]

Step-by-step explanation:

Given

The attached triangle

Required

Find tan(30)

Let the side opposite 30 degrees be A and the side adjacent 30 degrees be B

So [using tangent identity]:

[tex]tan(\theta) = \frac{Opposite}{Adjacent}[/tex]

This gives:

[tex]tan(30) = \frac{A}{B}[/tex]

Answer:

A spinner has equal sections numbered 1-8. If you spin the spinner once, what is the probability that you will not get a 5? | Socratic A spinner has equal sections numbered 1-8. If you spin the spinner once, what is the probability that you will not get a 5?

Step-by-step explanation:

Answer:

30 sq ft

Step-by-step explanation:

2 yd = 6ft

6 x 5=30

P = ½ * a * h

a = 2 yd = 2 * 3 ft = 6 ft

h = 5 ft

P = ½ * 6 * 5 = 30 sq ft

Answer:

Question unclear.

If the question was about the perimeter of the rectangle, it is calculated as:

= (Length * 2) + (Height * 2)

= (11 * 2) + (6 * 2)

= 22 + 12

= 34 cm

If the question was bout Area, the area is:

= Length * width

= 11 * 6

= 66 cm²

The value of x is 50 because, in a quadrilateral, the sum of the opposite angles is equal to 180 degrees. option (B) is correct.

It is defined as the four-sided polygon in geometry having four edges and four corners and two pairs of congruent sides.

We have:

In the diagram below, OP is circumscribed about quadrilateral ABCD.

In a quadrilateral, the sum of the opposite angles is equal to 180 degree

x + 20 + 110 = 180

x + 130 = 180

x = 50

Thus, the value of x is 50 because, in a quadrilateral, the sum of the opposite angles is equal to 180 degrees. option (B) is correct.

Answer:

one way to solve this question is to realize that every 100 pounds on planet A equals only 3 pounds on planet B.

So, 5000 pounds divided by 100 = 50. Then that number times 3 will give the weigh on planet B which is 150 pounds.

Algebraically, 100/3 = 5000/x; when we cross multiply, we get 15000/3 = x; x = 150

Answer:

she will be recivining $24.06

Step-by-step explanation:

4x3.99=15.96

2x4.99=9.98

15.96+9.98=25.94

50-25.94=24.06

Of course with out taxes

2x+y=9

3x+5y=19

I will do this problem in 2 ways. I.)Substitution II.)Elimination

Solution I.) Substitution

We can subtract 2x from both sides in the first equation.

y=9-2x

Now we can substitute the y in the second equation with 9-2x

3x+5(9-2x)=19

-7x+45=19

-7x=-26

x=26/7

y=9-2(26/7)=11/7

Solution II.)Elimination

We can multiply both side of first equation by 5 to get a 5y in both equations.

10x+5y=45

Now because both are positive 5y we just need to do simple subtraction of the 2 equation, each side respectively.

(10x+5y)-(3x+5y)=45-19

7x=26

x=26/7

2*26/7+y=9

y=11/7

Ultimately you get the same answer, both are viable methods, some problems are faster with one method but I recommend mastering both since they are very useful.

Answer: y = 1/5x + 6

Step-by-step explanation:

Let's break this up:

Radius: 19

Diameter: 38

Circumference: 119.4

So...

The area of a circle with radius 19 is 1134

A = πr2 = π(d

2

)2 A = C2

4π

π = 3.1415

A = area

C = circumference or perimeter

r = radius, d = diameter

SOLUTION STEPS:

Area of a circle in terms of radius:

Area = π·r2 = 3.14·192 = 1134 square cm(*)

Area of a circle in terms of diameter:

Area = π·(d

2

)2 = 3.14·(38

2

)2 = 3.14·(19)2 = 1134 square cm(*)

Area of a circle in terms of circumference:

Area = C2

4π

= 119.42

4π

= 14256.36

(4·3.14)

= 14256.36

12.56

= 1134 square cm(*)

(*) 1134.1149479459 cm, exactly or limited to the precision of this calculator (13 decimal places).

Note: for simplicity, the operations above were rounded to 2 decimal places and π was rounded to 3.14.

Result in other units of area:

A circle of radius = 19 or diameter = 38 or circumference = 119.4 cm has an area of:

1.134 × 10-7 square kilometers (km²)

0.1134 square meters (m²)

1134 square centimeters (cm²)

1.134 × 105 square millimeters (mm²)

4.3784 × 10-8 square miles (mi²)

0.135625 square yards (yd²)

1.22063 square feet (ft²)

175.77 square inches (in²)

Answer:

Step-by-step explanation:

Ok so basically 3 is 153 degrees and every line is 180 degrees, so 180-153=27.  So 3 and 2 make a line, 2 is 27 degrees and 4 and 3 make a line so that makes 4 -27 degrees. 1 is vertical to 3 and if 2 and 4 are 27 degrees and makes the lines with the other angles that equal 27 degrees then 1 is also 153 degrees.

Sorry if this is hard to understand. Good luck! :)

a is correct

Step-by-step explanation:

Area of Bigger rectangle = 4x2 + 5x - 2

Area of Smaller rectangle = x2 + 3× + 5

diff. = ( 4x2 + 5x - 2) - (x2 + 3x - 5)

= 4x2 + 5x -2-x2 - 3x - 5

= 3x2 + 2x - 7

Answer:

cats rule dogs drool

Step-by-step explanation:

just did it edge23

Answer:

Step-by-step explanation:

d is on a line with s so they are supplementary d+80 = 180 so d has to be 100

s and h are equal, therefore vertical angle x is also 80

Then 80 + 60 + y = 180 since they are on a straight line so y=40

Answer:

y=2x+5

Step-by-step explanation:

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

m=(9-(-1))/(2-(-3))

m=(9+1)/(2+3)

m=10/5

m=2

y-y1=m(x-x1)

y-(-1)=2(x-(-3))

y+1=2(x+3)

y=2x+6-1

y=2x+5
