Answer:

  rhombus

Step-by-step explanation:

It is helpful to plot the points on a graph. There, you can see that the rise and run of each segment are 1 and 4 (or vice versa). This tells you they are the same length, but not perpendicular.

A quadrilateral with all sides the same length, but not perpendicular, is a rhombus.

Leah knit a scarf that is 130 centimeters long, Theo knit a scarf that is 4/3 as long
Delvig [45]

Answer: Theo's scarf is  173 + 1/3 centimeters long.

Step-by-step explanation:

The scarf of Leah is 130 centimeters long.

The one of Theo is 4/3 as long as the one of Leah, then we have that the length of the scarf of Theo is:

Lenght = (4/3)*130 cm =(4*130)/3 cm =520/3 cm  

Now, we know that if all the digits of a number add up to a multiple of 3, that number is divisible by 3.

520/3 = (519 + 1)/3 = 519/3 + 1/3 = 173 + 1/3

Theo's scarf is  173 + 1/3 centimeters long.

Find the product of (x^2+2x-3)(4x^2-5x+6)
Evgesh-ka [11]

Answer:

x^{4} + 3x³ - 16x² + 27x - 18

Step-by-step explanation:

Each term in the second factor is multiplied by each term in the first factor, that is

x²(4x² - 5x + 6) + 2x(4x² - 5x + 6) - 3(4x² - 5x + 6)

Distribute all 3 parenthesis

= 4x^{4} - 5x³ + 6x² + 8x³ - 10x² + 12x - 12x² + 15x - 18

Collecting like terms

= 4x^{4} + 3x³ - 16x² + 27x - 18

60% of a number is 54. what is 50% of the same ?
tangare [24]

Answer:

The answer is 45.

Step-by-step explanation:

60% of a number is 54, find the original number

54 ÷ 60%

= 54 ÷ 60/100

= 54 * 100/60

= 90

50% of 90 is

90 * 50%

= 90 * 50/100

= 90 * 1/2

= 45
