WHAT IS THE TOTAL SURFACE AREA OF THE SQUARE PYRAMID???? THIS IS THE LAST QUESTION AND I ONLY HAVE 13 POINTS SO PLEASE ANSWER CORRECTLY!!!! :DD WILL GIVE BRAINLIEST AND 5 STARS AND THANKS IF YOUR RIGHT

Answer:

D. y = -1/2x + 18.5

Step-by-step explanation:

First you want to find the slope of the line that these coordinates make. To do this, use the slope formula: (y₂ - y₁) / (x₂ - x₁). I will use the first and last points.

(1, 18) & (6, 15.5)

Plug in these values:

(15.5 - 18) / (6 - 1)

Simplify the parentheses.

= (-2.5) / (5)

Simplify the fraction.

-2.5/5

= -1/2

This is your slope.

Now plug this into the standard slope-intercept equation: y = mx + b

y = -1/2x + b

b is the y-intercept, or the value of y when x = 0.

To find b, we want to plug in a value that we know is on this line: in this case, it is (1, 18). Plug in the x and y values into the x and y of the standard equation.

18 = -1/2(1) + b

To find b, multiply the slope and the input of x (1)

18 = -1/2 + b

Now, add 1/2 to both sides to isolate b.

18.5 = b

Plug this into your standard equation.

y = -1/2x + 18.5

This is your equation.

Hope this helps!

Answer:

([tex]\sqrt{5}[/tex] n - 4)([tex]\sqrt{5}[/tex] n + 4)

Step-by-step explanation:

Using the factorising method, difference of 2 squares

a² - b² = (a - b)(a + b) , then

5n² - 16

= ([tex]\sqrt{5}[/tex] n )² - 4²

= ([tex]\sqrt{5}[/tex] n - 4)([tex]\sqrt{5}[/tex] n + 4)

Answer:

2

Step-by-step explanation:

The answer would be 2 because it reduces to the same system of equations as the original, which I knew since the first equation was the same and if you divide everything in the second by 2, you'll get 3x-y=8. :)

Answer:

BE=15

Step-by-step explanation:

Since E is the center, BE=2x+1

And AC is 6x-12 with E being a midpoint.

Since AC is 2 segments and BE is only 1 then you multiply 2x+1 by 2 so that

you can find x. You multiply 2x+12 by 2 because E is the midpoint so that means ED is the same value as BE

6x-12=4x+2

BD=AC

6x-4x-12=2

2x=2+12

2x=14

x=7

BE= 2x+1

2(7)=14+1=15

Answer:

It's B

Step-by-step explanation:

Line segment TU is parallel to line segment RS because 32/36 = 40/45.

According to the "Side Splitter" Theorem, a line that crosses two sides of a triangle and runs parallel to its third side proportionally divides those two sides.

A line will divide two sides of a triangle proportionally if it runs parallel to one of the sides and intersects the other two.

Given

It is evident from the presented figure that QT=32, TR=36, QU=40, and US=45.

The opposite of the side splitter theorem asserts that a line is parallel to a third side if it divides two sides proportionally.

TU separates the two sides by a factor of in

QT/TR = 32/36 = 8/9

QU/US = 40/45 = 8/9

QT/TR = QU/US

It implies that the line TU divides the two sides equally.

Line segment TU is parallel to line segment RS using the reverse of the side splitter theorem because

32/36 = 40/45

Hence option 1 is correct.

The complete Question is,

Answer:

36 square inches.

Step-by-step explanation:

Since the original figure was a square, all four side lengths are equivalent. The area for the square will be:

[tex]A=s^2[/tex]

Where s is the length of one side.

One side is increased by nine inches and the other side was decreased by two inches. The area of the resulting rectangle is 60 square inches.

So, one of the new sides is (s + 9).

And the other is (s - 2).

The area with these dimensions is 60. Thus:

[tex]60=(s-2)(s+9)[/tex]

Solve for s. Distribute:

[tex]60=s^2+7s-18[/tex]

Isolate the variables:

[tex]s^2+7s-78=0[/tex]

Factor:

[tex](s+13)(s-6)=0[/tex]

Zero Product Property:

[tex]s+13=0\text{ or } s-6=0[/tex]

Solve for each case:

[tex]s=-13\text{ or } s=6[/tex]

A side length cannot be negative. So, our only solution is:

[tex]s=6\text{ inches}[/tex]

Since each side of the square measures six inches, the area of the original square will be 36 square inches.

Answer:

Step-by-step explanation:

use the law of Cosines so that you can solve a SSS triangle

Cos(C) = [tex]a^{2}[/tex] + [tex]b^{2}[/tex] - [tex]c^{2}[/tex]  / 2ab

c is the side of 24 for our triangle and angle C is the top one in the picture.

C = arcCos ( [tex]a^{2}[/tex] + [tex]b^{2}[/tex] - [tex]c^{2}[/tex]  / 2ab )

C = arcCos ( -32 / 480 )

C = 93.82255373 °

the angles at the top are each half of that or 46.91127 °

let's solve another angle for the big triangle now let's go for the one on the left and call it A

Cos(A) = [tex]c^{2}[/tex] + [tex]b^{2}[/tex] - [tex]a^{2}[/tex]  / 2bc   where a = 20

A = arcCos( [tex]c^{2}[/tex] + [tex]b^{2}[/tex] - [tex]a^{2}[/tex]  / 2bc)

A = arcCos( [tex]24^{2}[/tex] + [tex]12^{2}[/tex] - [tex]20^{2}[/tex] / 2*12*24

A = arcCos(320 / 576)

A = 56.2510 °

then angle B is  180 =93.823 + 56.251 + B

29.926 ° = B

so now we know all 3 angles.. seems like a lot of work , huh  :D

for the triangle with the question mark we now know two angles and the Hyp, so let's use Law of Sines to find that last side  :)

Sin(A)/a = Sin(B) /b  where A can be the angle at the top and B can be the angle at the base. which we have to find still  :/  

it's 180 = 46.9112 + 29.926 + B

103.162 = B

Sin(46.91127 ) / a = Sin(103.162) /20

Sin(46.91127 ) * 20 / Sin(103.162) = a

14.99998 = a    I feel confident this is supposed to be 15 and I have a tiny bit of rounding error..

? = 15   there you go  

your answer is 15

Answer:

Step-by-step explanation:

The sum of the three interior angles of a triangle is always 180.

Knowing this, we can set up an equation for the given angles:

[tex]8x + 10x + 12x = 180[/tex]

[tex]30x = 180[/tex]

[tex]x = 6[/tex]

Knowing this, we can now plug it into the angles:

[tex]8x[/tex]

[tex]8 * 6[/tex]

[tex]48[/tex]

[tex]10x[/tex]
