Ans? u9999y

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.

The triangle is not a right triangle, but in step 3, Chelsea incorrectly rewrote the expression on the left side of the equation.

Step-by-step explanation:

<u>Step 1: Define</u>

f(x) = 3x² + 2x - 3

f(3) is x = 3

<u>Step 2: Evaluate</u>

  1. Substitute in <em>x</em>:                    f(3) = 3(3)² + 2(3) - 3
  2. Exponents:                          f(3) = 3(9) + 2(3) - 3
  3. Multiply:                               f(3) = 27 + 6 - 3
  4. Add:                                     f(3) = 33 - 3
  5. Subtract:                              f(3) = 30

The shorter side of a trapezoid is equal to its height, and the longer side is 3/2 times as long. If the area is 80, find the le
lara31 [8.8K]

Answer:

  8

Step-by-step explanation:

Let s represent the length of the shorter base and height. Then (3/2)s is the length of the longer base.

The area formula for a trapezoid is ...

  A = 1/2(b1 +b2)h

Filling in the given values, we have ...

  80 = (1/2)(s +3/2s)s = 5/4s²

  64 = s² . . . . . . . . . . . . . . . . . . . multiply by 4/5

  8 = s . . . . . . . . . . . . . . . . . . . . . take the square root

The length of the shorter side is 8.
