A rectangle has a length of x+5 cm and a width of x cm. The perimeter of the rectangle is 50 cm. What is the value of x?

Answers

Answer:x=10

Step-by-step explanation:

First let's create an equation:

2(x+5)+2x=50

2x+10+2x=50

4x+10=50

4x=40

x=10

Answer:

x = 10

Step-by-step explanation:

perimeter is the sum of all sides

2 sides = 'x+5' cm

2 sides = 'x' cm

2(x + 5) + 2x = 50

2x + 10 + 2x = 50

4x + 10 = 50

4x = 40

x = 10

I don’t know if this is right or not so, sorry if it’s wrong ;-;

1,2,3,4,5 = independent

Number of avocados = independent

Cost of avocados = dependent

Which of the following equations have two complex solutions? Select all that apply.
(CHECK IMAGE ATTACHED)

Answers

Correct Answer: A and F!!

A- 3x^2+ 5x + 10=0

F- 2x^2 + 12 = -9x

Step-by-step explanation: Just did it and it’s right, hope that helped!! :)

The equations that have two complex solutions are 3x^2 + 5x + 10 = 0 and 2x^2 + 12 = -9x

For a quadratic equation to have a complex solution, hence the discriminant must be less than zero.

The discriminant is expressed as:

D = b^2 - 4ac

For the equation 10x^2 - 10 = 0

D = 0^2 - 4(10)(-10)

D = 400

Option B is false.

For the equation 3x^2 + 5x + 10 = 0

D = 5^2 - 4(3)(10)

D = 25 - 120

D = -95

Since D < 0, hence the equations 3x^2 + 5x + 10 = 0 have two complex solutions

For the equation 2x^2 + 12 = -9x

D = 9^2 - 4(2)(12)

D = 81 - 96

D = -15

Since D < 0, hence the equations 2x^2 + 12 = -9x have two complex solutions

Question: This pile of gold (photo below) is worth $50,000. Shrink the pile ( I already did it for you:) so that it is 18% of its height.

How much will the gold be worth? Explain your thinking.

Answers

Answer:

I beleive the answer is $9000

Step-by-step explanation: What is 18% of 50000?

Y is 18% of 50000

Equation: Y = P% * X

Solving our equation for Y

Y = P% * X

Y = 18% * 50000

Converting percent to decimal:

p = 18%/100 = 0.18

Y = 0.18 * 50000

Y = 9000

9000 is how much is taken off, just take 18% of 50000=9000
50000-9000=41,000.
After 18% is taken off it’s $41,000
It asked for how much the gold would be worth not how much is taken off.
