Answer:

Both of them

Step-by-step explanation:

-2*-3 = 6

So -2(-3)(4) is equal to 6(4).

-3*4 = -12

So -2(-3)(4) is equal to -2(-12).

Answer:

3, 130 degrees

Step-by-step explanation:

Angles TUW and VUW are congruent, so their opposite sides will be congruent as well

GF and IF are congruent, so their opposite angles will be congruent as well. 65 + 65 is 130 degrees.

6. If s is the number of programs sold for $0.45 each, then the contribution to Devon's pay (p) from selling programs is 0.45s. The per-game pay is added to that to give Devon's total pay:

  p = 0.45s + 40 . . . . . matches choice A

__

7. If Robert earns $25 per hour for x hours in tips, his tip pay is 25x. The flat rate is added to that to give the amount Robert makes:

  y = 25x + 40 . . . . . matches choice C

8. The graph of a proportional relationship is a straight line through the origin. This description matches B and C only, choice E.

Answer:

C. The area is 900 square feet

Step-by-step explanation:

A square has four equal sides, and if one side is 30 feet then all sides are 30 feet. The formula for a square is A=s2

A=30 squared

A=900 square feet

Answer:

C) 900 square feet

Step-by-step explanation:

A = s^2

A = 30^2 ->30^2 is the same as 30 × 30

A = 900 square feet

Answer:

1. 20x+8=48 2. x=2 3. the area of the square is 144units^2

Step-by-step explanation:

assuming its a perfect 4 sides square the total perimeter would be 5x + 2 units multiplied by 4 = the perimeter so 20x+8 = 48

20x+8=48

subtract 8 from both sides

20x=40

divide 20

x = 2 units

For area plug x back into 5x+2 and you will get 12 units for one side and all sides here should be 12 units so multiply one side with another

12 x 12 = 144 units^2

Answer:

Well I answered in the comments, but I need points so the answers are (in order) 12, 2, and 144

Step-by-step explanation:

Since it's a square, the sides will be the same length. If the perimeter is 48, then you divide 48 by 4 and you will have 12- your answer.

For x, subtract 2 from 12 to get ten, then divide that by five to get your answer which would be 2.

If the side length is 12, you square that and 12 squared is 144.

Answer:

For 3x + 5y = -13 the answer is x= -13/3 + 5y/3

and for 2x + 15y=3 the answer x= 1.5 + (-15y/2)

Step-by-step:

For 3x+5y=-13 you have to add 5y on both sides. Then you have to divide by 3 on both sides and cancel out the common factor of 3. Then you would get x= 13/3 + 5y/3.

For 2x + 15y=3 you have to subtract 15y on both sides of the equation. You should have 2x=3 + (-15y). Then divide by 2 on both sides. 3 divided by 2 is 1.5 and -15y divided by 2 is -15y/2 since 2 doesn't have the same variable. so the answer should be x= 1.5 + (-15y/2).

Answer:

The quadrilateral ABCD is a parallelogram

Step-by-step explanation:

The vertices of the quadrilateral ABCD are;

A(-2 -2), B(5, -2), C(4, -3)and D(-3, -3)

The slope of segment [tex]\overline {AB}[/tex] = (-2 - (-2))/(5 - (-2)) = 0

The length of segment [tex]\overline {AB}[/tex] = 5 - (-2) = 7 (points having the same y-coordinates)

The slope of segment [tex]\overline {AD}[/tex] = (-3 - (-2))/(-3 - (-2)) = 1

The length of segment [tex]\overline {AD}[/tex] = √((-3 - (-2))² + (-3 - (-2))²)  = √2

The slope of segment [tex]\overline {DC}[/tex] = (-3 - (-3))/(-3 - 4) = 0

The length of segment [tex]\overline {DC}[/tex] = 4 - (-3) = 7 (points having the same y-coordinates)

The slope of segment [tex]\overline {BC}[/tex] = (-3 - (-2))/(4 - 5) = 1

The length of segment [tex]\overline {AD}[/tex] = √((4 - 5)² + (-3 - (-2))²)  = √2

Therefore;

The opposite sites of the quadrilateral ABCD are equal; [tex]\overline {AB}[/tex] = [tex]\overline {DC}[/tex], [tex]\overline {AD}[/tex] = [tex]\overline {BC}[/tex]

Given that the slope of a line gives the inclination of the line on a graph, we have;

The opposite sites of the quadrilateral are parallel; [tex]\overline {AB}[/tex] ║ [tex]\overline {DC}[/tex], [tex]\overline {AD}[/tex] ║ [tex]\overline {BC}[/tex]

Therefore the quadrilateral ABCD is a parallelogram because the opposite sides of the quadrilateral ABCD are parallel.

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

The graph shows a turning point at x = - 1

This indicates a zero at x = - 1 with multiplicity 2

The corresponding factors are (x + 1) and (x + 1), thus

y = (x + 1)(x + 1) ← best describes the graph

Answer:

The answer should be, x ÷ 180 or [tex]\frac{x}{180}[/tex]

good luck, i hope this helps :)

Answer:

20 liters

Step-by-step explanation:

The computation of the number of liters does it pump in 1 second is shown below:

Since the borehole pumps 7,2 kl of water i.e. 72,000 liters in one hour

Now the number of liters in 1 second is

= 72,000 × 1 seconds ÷ 3,600 seconds

= 20 liters

Answer:

[tex]24\pi \: cm {}^{2} [/tex]

Step-by-step explanation:

The area of a cone is

[tex]\pi \times r {}^{2} + \pi \times r \times \sqrt{ {r }^{2} + {h}^{2} } [/tex]

The volume of the conical paper cup will be option (D) 24π

The steps are as follow:

r = base radius = 3 cm

h = height of cone = 8 cm

V = volume of cone = (1/3)πr²h.

V = (1/3)π*3²*8.

V = 24π

So, the volume of the conical paper cup will be option (D) 24π
