x² - x + 4x - 4 → D

Expand using the FOIL method

F → multiply First terms → x and x = x²

O → multiply the Outer terms → - 1 and x = - x

I → multiply the Inner terms → 4 and x = 4x

L → multiply the last terms → 4 and - 1 = - 4


(x + 4)(x - 1) = x² - x + 4x - 4

Select all shapes that have a volume of \small 36\pi cubic units.
Gnesinka [82]

Answer:

Step-by-step explanation:

Chelsea is making a kite in the shape of a triangle. To determine if the triangle is a right triangle, Chelsea completed the following steps.

Step 1:

Find the side lengths of the triangle: 30 inches, 24 inches, 18 inches.

Step 2:

Substitute the values into the Pythagorean theorem: 18 squared + 24 squared = 30 squared.

Step 3:

Combine like terms: (18 + 24) squared = 30 squared.

Step 4:

Evaluate each side: 1764 not-equals 900.

Chelsea says the triangle is not a right triangle. Which best describes the accuracy of her explanation?

The triangle is actually a right triangle. In step 2, Chelsea incorrectly substituted the values into the Pythagorean theorem.

The triangle is not a right triangle, but in step 2 Chelsea incorrectly substituted the values into the Pythagorean theorem.

The triangle is actually a right triangle. In step 3, Chelsea incorrectly rewrote the expression on the left side of the equation.
