HELP, 7th grade math

Answer:

x2+x-4=0

Step-by-step explanation:

Answer:

-7i - 9

-11i + 12

Step-by-step explanation:

i stands for imaginary number, in which i² = -1

6i² = 6 * -1 = -6

-6 - 7i - 3

Combine like terms:

-6 - 3 = -9

-7i - 9

2i^2 = 2 * -1 = -2

Combine like terms:

-11i + 14 - 2

-11i + 12

Answer: 40 ft^3

Step-by-step explanation:

l*w*h to find volume of space in the drawer so

5*4=20 and 20*2= 40 so the volume is 40

Answer:

The area is 40 square feet.

Step-by-step explanation:

To find area, you multiply length x height x width. 5x4x2=40

Answer:

x = 5

Step-by-step explanation:

6x - 3 = 3x + 12

-3x       -3x

_____________

3x - 3 = 12

    +3    +3

_____________

3x = 15

15 divided by 3 = 5

x = 5

You can double check this by replacing x with (5)

If it is right both sides should equal the same

6(5) - 3 = 3(5) + 12

30 - 3 = 15 + 12

27 = 27

This would prove that x = 5

Answer:

[tex]QR = 6.0033[/tex]

[tex]QS = 8.22[/tex]

[tex]RS = 6.0033[/tex]

QRS is isosceles

Step-by-step explanation:

Given

See attachment for complete question

From the attachment, we have the following parameters[tex]QR = \sqrt{(-3-0)^2+(-5.2-0)^2}[/tex]

[tex]QR = \sqrt{9+27.04}[/tex]

[tex]QS = \sqrt{(-3-5)^2+(-5.2-(-3.322))^2}[/tex]

[tex]QS = \sqrt{64+3.53} = \sqrt{67.53[/tex]

[tex]RS = \sqrt{(0-5)^2 + (0 - (-3.322))^2}[/tex]

[tex]RS = \sqrt{(25 + 11.04}[/tex]

Solving further, we have:

[tex]QR = \sqrt{9+27.04}[/tex]

[tex]QR = \sqrt{36.04}[/tex]

[tex]QR = 6.0033[/tex]

[tex]QS = \sqrt{64+3.53} = \sqrt{67.53}[/tex]

[tex]QS = 8.22[/tex]

[tex]RS = \sqrt{25 + 11.04}[/tex]

[tex]RS = \sqrt{36.04}[/tex]

[tex]RS = 6.0033[/tex]

From the calculations;

[tex]RS = QR = 6.0033[/tex]

This means that: QRS is isosceles

Answer:

1 hour 37 minutes

Step-by-step explanation:

Given that :

Time Amelia started puzzle = 12 : 56

Time Amelia solved puzzle = 2 : 33

The time it took Amelia to solve puzzle :

Time Amelia solved puzzle - Time Amelia started puzzle

2 : 33 - 12 :56

12 :56 to 1 :56 = 1hr

1:56 to 2:33 = 37 minutes

Total time spent on puzzle = 1 hour + 37 minutes = 1 hour 37 minutes

The table shows a linear function :)

Answer:

Step-by-step explanation:

9/2 is the slope. Slope defines how steep is the straight line.

Slope =  change in y ÷ change in x

In this model, 9 refers to the vertical distance between two points

and 2 refers to  the horizontal distance between two points.

9/2 is a positive slope. It indicates that if 'x' increases, y also increase.

Answer:

gustavo is wrong

Step-by-step explanation:

Answer:

v = 60

Step-by-step explanation:

65 + 55 + v = 180

65 + 55 = 120

180 - 120 = 60

v = 60

Answer: B

Step-by-step explanation:

y intercept is -2

y = 3/2x^2 + 4x – 2

y = 3/2(0^2) + 4(0) – 2 = -2

and x intercepts are

0 = 3/2x^2 + 4x – 2

Step-by-step explanation:

Answer:

12.25 cm^2

Step-by-step explanation:

Draw a segment from the bottom of the 1.5-cm vertical side to the bottom side of the entire polygon.

Now you have two rectangles.

The left rectangle has dimensions 3.5 cm by 1.5 cm.

The right rectangle has length 5 cm - 1.5 cm = 3.5 cm and width 3.5 cm - 1.5 cm = 2 cm.

The total area is the sum of the areas of the two rectangles.

area of rectangle = length * width

total area = 3.5 cm * 1.5 cm + 3.5 cm * 2 cm

total area = 5.25 cm^2 + 7 cm^2

total area = 12.25 cm^2

Answer:

[tex]\sqrt{117}[/tex] or [tex]3\sqrt{13}[/tex]

Step-by-step explanation:

The formula for finding the any side of the triangle is

[tex]a^{2}+b^{2} =c^{2}[/tex]

We know that a=2 and c=11, so we can go ahead and plug those into the formula.

[tex]2^{2}+b^{2} =11^{2}[/tex]

[tex]4+b^{2} =121[/tex]

To find side b, we have to make it alone on one side. Subtract 4 on both side.

[tex]b^{2} =117[/tex]

Now square root both sides, and that leaves us with:

[tex]b=\sqrt{117}[/tex] or [tex]3\sqrt{13}[/tex]
