Use four unit multipliers to convert 630 square yards into square inches
vagabundo [1.1K]
We are asked to determine the unit multipliers in order for us to convert 630 square yards to into square inches. Well, first we need to convert square yards to square feet and secondly, we convert square feet to square inches.
square yards -> square feet -> square inches
We also take note the following:
1 yard = 3 feet
1 foot = 12 inches
The solution in converting the unit is shown below:
630 yards² * (3 feet / 1 yard)² = 5670 feet²
5670 feet² * (12 inches / 1 foot)² = 816,480 inches²

The answer is 816,480 inches².

Find a polynomial function of lowest degree with
ra1l [238]

Answer:

x^3-4x^2+25x-100

Step-by-step explanation:

We have 2 roots -5i and 4. Using the conjugate root theorem for the root -5i, we know that 5i should be another root

Combining the roots into a polynomial gives us:

(x+5i)(x-5i)(x-4)

Expand:

(x^2 + 25)(x-4)

x^3-4x^2+25x-100
