What is the area of a right angled triangle having base 10 cm and height 5 cm?

Answer: x = 2, 1

Step-by-step explanation:2x^2 - 6x + 4 = 0

Firstly, simplify. Divide by 2 to get

2(x^2-3x+2) = 0

Move the constant to the other side.

2(x^2-3x) = -2

Divide the x term by 2 and square it

-3/2^2 = 9/4

Add this result to both sides.

2(x^2-3x+9/4) = 1/4.
Put the perfect sq on both sides
2(x-3/2)^2=1/4
Then solve the equation:

take the sqrt of both sides and isolate x for each solution

x-3/2= +/-1/2
x = 3/2 + 1/2
x= 3/2-1/2
x= 2, 1

If Elena earn y = 8.40x dollars where x represent how many hours she work and Jada earn $7 per hour, it would take Elena approximately 17.86 hours and Jada approximately 21.43 hours to earn $150

To find out how many hours it would take for Elena to earn $150, we need to solve the equation:

y = 8.4x

150 = 8.4x

x = 150/8.4

x ≈ 17.86 hours

So it would take Elena approximately 17.86 hours to earn $150.

To find out how many hours it would take for Jada to earn $150, we divide 150 by her hourly rate:

= $150 /( $7/ hour)

≈ 21.43

So it would take Jada approximately 21.43 hours to earn $150.

You can tell if a table shows a proportional relationship by calculating the ratio of each pair of values.

The table depicts a proportionate relationship if all of those ratios are the same.

If all of the ratios of the variables are equal, then there is a proportional link between the two variables.

In proportional relationships, one variable is, in other words, always a constant value multiplied by the other variable. The proportionality constant is the name given to the constant value. A mathematical equation of the form y=kx, where k is the proportionality constant, can be used to model any proportional relationships. The unit rate is another name for the proportionality constant.

Answer:

Step-by-step explanation:

x+12=y

2x+12=56

2x=44

x=22

y=56-22

y=34

x=22

hope this helps

Answer:

34 and 22

Step-by-step explanation:

x + y = 56   Add the two equations together

x - y = 12

2x     = 56  Divide both sides by 2

x = 34

substitute 34 for x in either of the two original equations to solve for y

x + y = 56

34 + y = 56   Subtract 34 from both sides

y = 22

Check:

x + y = 56

34 + 22 = 56  Checks

x - y = 12

34 - 22 = 12

12 = 12  Checks

An expression to represent the perimeter of the rectangle with  10/(x² + 11x +24) and (x+1)/(x+3) would be (x+12)(x+6)//(x+8)/(x+3).

What is the perimeter?

A closed path that covers, encircles, or outlines a one-dimensional length or a two-dimensional shape is called a perimeter. A circle's or an ellipse's circumference is referred to as its perimeter. There are numerous uses in real life for perimeter calculations.

Here, we have

Given: Sides = 10/(x² + 11x +24) and (x+1)/(x+3)

The perimeter is when you add all the sides of a shape.

In a rectangle, two sides are the same, and so are the other two. therefore, if the two sides are 10/(x² + 11x +24) and (x+1)/(x+3) the expression will be:

= 2(10/(x² + 11x +24)) + 2(x+1)/(x+3)

= 20/(x² + 11x +24) + 2(x+1)/(x+3)

= 20/(x+8)/(x+3) + 2(x+1)/(x+3)

= {20 + 2(x+1)(x+8)}/(x+8)/(x+3)

= {20 + 2(x² + 9x + 8)}/(x+8)/(x+3)

= { 20 + 2x² + 18x + 16}/(x+8)/(x+3)

= {2x² + 18x + 36}/(x+8)/(x+3)

= (x+12)(x+6)//(x+8)/(x+3)

Hence, an expression to represent the perimeter of the rectangle with  10/(x² + 11x +24) and (x+1)/(x+3) would be (x+12)(x+6)//(x+8)/(x+3).
