Which equation can be used to find the length of AC?

Answer:

SA =12.

Step-by-step explanation:

In a parallelogram the diagonals bisect each other , so:

2x - 1 = x + 7

2x - x = 7 + 1

x = 8.

QS = x + 4 = 8 + 4

= 12.

But QS = SA, so SA =12.

Answer:

=180-31+40

=180-71

=109

Answer:78.5

Step-by-step explanation:

the median is the middle digit so with 10 different numbers it would be the 5th or sixth number  

but you have to first have them in least to greatest order

53,59,68,70,75,82,82,87,94,95

5th+6th/2

75+82= 157

157/2

78.5

Answer: 2x=74

Step-by-step explanation:

Every triangle is 180 degrees.

so you will take 180-32= 148

then with that you will add up the x's and there are 4...

so then you will take 148/4 and get the answer of...

148/4=37

x=37

but it asked for 2x

37*2

2x=74

final answer is 74

A) The wall is larger than you, so no force is exerted

Step-by-step explanation:

Answer:

a + (b + c) = (a + b) + c

Step-by-step explanation:

a= (-12), b = 4, c = (-25)

[tex](12) + (4 + ( - 25)) = ( - 12 + 4) + ( - 25) \\ - 33 = - 33[/tex]

Answer:

GIVEN :-

TO VERIFY :-

SOLUTION :-

Find the values of L.H.S. & R.H.S.

L.H.S. :-

Put all values in → [tex]\boxed{a+(b+c)}[/tex]

⇒ -12 + [4 + (-25)]

⇒ -12 + (4 - 25)

⇒ -12 + (-21)

⇒ -12 - 21

⇒ -33

R.H.S. :-

Put all values in → [tex]\boxed{(a+b)+c}[/tex]

⇒ (-12 + 4) + (-25)

⇒ -8 - 25

⇒ -33

CONCLUSION :-

L.H.S. = R.H.S.

⇒ a + (b + c) = (a + b) + c

Answer:

Measure of obtuse angle is 134 degrees

Step-by-step explanation:

these two angles are supplementary so they add up to 180

68x-2 +23x=180

91x-2=180

91x = 182

x = 2

plug in x

68 (2) -2 = 134

23 (x) = 46

Answer:

multiplying by 2.3 is the opposite

Answer:

[tex]Height = 7in[/tex]

Step-by-step explanation:

Given

See attachment for parallelogram

[tex]Base = 28in[/tex]

Required

What is the height?

The opposite sides of a parallelogram are equal and the height is the distance between the parallel sides.

From the question, we have:

[tex]Base = 28in[/tex]

Also from the question, the difference between the two parallel sides is 7in.

Hence, the height of the parallelogram in 7in

A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation. Using this equation, find the time that the rocket will hit the ground, to the nearest 100th of second.

y=-16x^2+129x+119

y=−16x

Step-by-step explanation:

Answer:

Step-by-step explanation:

-2÷1 = -2

4÷(-2) = -2

-8:4 = -2

So this is a geometric sequence with a common ratio of -2

Therefore:

the 5th term:   -8×(-2) = 16

the 6th term:   16×(-2) = -32

Answer:

area = 82 cm²

Step-by-step explanation:

The figure comprises a trapezoid, a triangle and a square.

Calculating areas of the three shapes separately and then adding them will give us the required area of the composite figure.

Area of square : (side)²

= (2)²

= 4 cm²

Area of triangle : ½ × b × h

= ½ × 3 × 12

= 3 × 6

= 18 cm²

Area of trapezoid : ½ × (a + b) × h

= ½ × (5+5) × 12

= ½ × 10 × 12

= 5 × 12

= 60 cm²

Now, area of the composite figure :

= 4 + 18 + 60

= 22 + 60

= 82 cm²

Answer:

Step-by-step explanation:

If you exclude the square on the bottom, you have a trapezoid with bases of 5 cm and 8 cm and the height of 12 cm.

Its area is:

Add the area of the square with sides of 2 cm:

Total area is:
