Answer:

Step-by-step explanation:

Evaluate 5 x^2 - 3 (x - 2) + x where x = 3:

5 x^2 - 3 (x - 2) + x = 5×3^2 - 3 (3 - 2) + 3

3^2 = 9:

5×9 - 3 (3 - 2) + 3

3 - 2 = 1:

5×9 - 3 + 3

5×9 = 45:

45 - 3 + 3

45 + 3 = 48:

48 - 3

| 4 | 8

- | | 3

| 4 | 5:

Answer: 45

What is the volume of the triangular prism shown below?

liberstina [14]

Answer:

Step-by-step explanation:

The volume (V) of the triangular prism is calculated as

V = area of triangular face × length

Area of triangle = $\frac{1}{2}$ bh ( b is the base and h the height )

Here b = 6 and h = 8, thus

Area = $\frac{1}{2}$ × 6 × 8 = 3 × 8 = 24 units², thus

V = 24 × 20 = 480 units³ → B

Explain howyou wouldestimateto subtract 189 from 643

kupik [55]

I would estimate 643 - 189 by rounding 643 to the tens place and 189 to the hundreds place.

643 => 640

189 => 200

Now you can subtract 200 from 640.

640 - 200 = 440
