Hey there!

First we expand then can find the asnwer by simplifying:

\((5x^2-3x+5)-(-6x^2+3x+8)\)

\(5x^2-3x+5+6x^2-3x-8\)

\(11x^2-6x-3\)

Hope this helped :)

Use. your. brain dummie  DUH

please include the address of the first question.

We can solve this with a system of equations.

Let l represent the rectangle's length.

Let w represent the rectangle's length.

We know that:

l = 3w - 9

and 

Perimeter = 222

Since the perimeter is simply 2(l+w);

2(l+w) = 222

l + w = 111

Now substitute in 3w +9 into l + w = 111:

l + w = 111

(3w - 9) + w = 111

4w - 9 = 111

4w = 120

w = 30

l = 3w - 9

l = 3(30) - 9

l = 90 - 9

l = 81

Therefore the length is 81 ft, and the width is 30 ft.

For the minute hand to 60 minutes is a full rotation of the clock, or 360°.

5:45 - 5:35 = 10 minutes.

10 minutes is 1/6 of 60 minutes, so 10 minutes is 1/6 of 360° = 60°.

Now we can calculate the arc using the angle of 60°.

Arc length = (60/360)(πr²)

                  = (1/6)(3.14)(6²)

                  = 18.84

Therefore, the length of the arc made by the hand is 18.84 inches.

First, find the area of the picture:

5*7 = 35 in²

The area of just the frame is:

80 - 35 = 45 in²

Now, note that the frame is nothing but 4 equal squares for the corners of the frame and 4 rectangles.

The corners have an area of x².

Two of the rectangles have an area of 5x, and the other 2 have an area of 7x.

Therefore the area of the frame is

4(x²) + 2(5x) + 2(7x) = 4x² + 24x

Which equals:

4x² + 24x = 45

Solving the quadratic, we get:

4x² + 24x = 45

4x² + 24x - 45 = 0

(2x-3)(2x+15) = 0

 2x - 3 = 0

2x = 3

x = 1.5

(The other solution for x would be negative)

Therefore, the width is 1.5 in².

Solved! :)

The number of seven-digit telepone number is 14876.

Area of triangle BOC cannot be 20 square units!!! 

the probability she draws a red marble is $\frac{5}{12}.$ 

since there's no replacement, we now have a pool of 11 marbles to pick from. the chance of picking a blue marble from this is $\frac{4}{11}.$

multiplying the two fractions, we have $\frac{5 \cdot 4}{12 \cdot 11} = \frac{20}{132} = \boxed{\frac{5}{33}}$

please confirm if this is wrong or not as my alcumus rating for counting and probability is very low  

if i get this problem right, it will be very lucky for both you and me 

Why are you answering your own question?

Are you sure?

Please tell explanation.

We can compare the areas of the shapes to the probability that points will get chosen inside them.

Area of the Triangle = bh/2

                                 = 7*4/2

                                 = 14 m²

Area of the Trapezoid = (ab/2)h

                                    = (8*13/2)*4

                                    = 52*4

                                    = 208 m²

Area of the Rectangle = bh

                                    = 17*25

                                    =  425 m²

Now, the final probability is =

\({14 + 208}\over{425}\)

= 222/425

A dozen is 12; thus 12 dozen is 12*12 = 144.

144/36 = 4

 Therefore Denis is making 4 times as many cookies; meaning he needs 4 times the ingredients.

(1 1/2) * 4 = 6 cups of flour

(2 3/4) * 4 = 11 cups of sugar

(1/8) * 4 = 1/2 cup of milk

Thus Denis needs 6 cups of flour, 11 cups of sugar, and 1/2 cup of milk to make 12 dozen cookies.

LOL!!!

Since  AB = AC, the  angles  ABC = ACB  = 72°

Bisecting  angle  ABC  means that  angle  ABD =  angle BAD  = 36°

Therefore....in triangle   ABD......AD = BD

And the  thitd  angle in this triangle, BDA  =  108°

So angle  BDC   =  180  - 108°  =  72°

And  angle  ACB =  DCB = 72°

So.....in triangle  BDC, angle  DCB = angle BDC    

So  BD = BC

So

BC =  BD  = AD

$g(x) = \frac{x + 9}{2}$ is the inverse function of $f(x) = 2x - 9$, and vice versa. your answer is $B.$ nice

The first option, $A = 8(15) + \frac{1}{2}(15 \cdot 7) + \frac{1}{2}(9 \cdot 8).$

$8(15)$ finds the area of the rectangle, $\frac{1}{2}(15 \cdot 7)$ finds the area of the triangle residing on top of the rectangle, and $\frac{1}{2}(9 \cdot 8)$ finds the area of the triangle to the right.

hello there

hi centslordm

dude, you just one-upped me like an absolute god

6x + 8y - 3z = -10     (1)

2x + 8y - 5z = 2        (2)

-5x - 8y + 4z = 7       (3)

Add ( 1)  and (3)   and we have

x + z =   -3       (4)

Add ( 2)  and (3)  and we have

-3x - z  =  9         (5)

Add ( 4)  and (5) and we  have  that

-2x  =  6

x =  6 /  -2  =  -3

And

x + z  = -3

-3 + z  =  -3

z  = 0

And

6(-3)  + 8y  - 3(0) = -10

-18   + 8y  = -10

8y  = 8

y  = 1

So  ( x,  y , z)  =   ( -3 , 1 , 0)  as CentsLord  found
