  1. Substitute in <em>x</em>:                                                                                                  (-1)³ + 3(-1)² = -1 + 3
  2. Evaluate exponents:                                                                                         -1 + 3(1) = -1 + 3
  3. Multiply:                                                                                                             -1 + 3 = -1 + 3

#4 find the value of x. Round answer to nearest tenth.
igomit [66]

Answer:

Step-by-step explanation:

From the given right angle triangle,

The unknown side represents the hypotenuse of the right angle triangle.

With m∠40 as the reference angle,

x represents the adjacent side of the right angle triangle.

4 represents the opposite side of the right angle triangle.

To determine x, we would apply

the Tangent trigonometric ratio.

Sin θ = opposite side/hypotenuse. Therefore,

Tan 40 = 4/x

x = 4/Tan 40 = 4/0.839

x = 4.8
