Tim wants to determine the height, x, of a nearby tree. He stands 35 feet
kodGreya [7K]

Answer:

x ≈ 29.4 ft

Step-by-step explanation:

The model is a right triangle.

Using the tangent ratio

tan40° = \frac{opposite}{adjacent} = \frac{x}{35} ( multiply both sides by 35 )

35 × tan40° = x , then

x ≈ 29.4 ft ( to 1 dec. place )

Answer:

Option C:   $ \sqrt{\textbf{121}} $

Step-by-step explanation:

Given the side length of a square is 11 units.

Note that $ \sqrt{121} = \pm 11 $

Since, length cannot be negative, we can eliminate - 11.

Hence, the length of the side of the square is 11 units = $ \sqrt{11^2} = \sqrt{121} $.

Hence, the answer.

4x2 + 8x - 7 - (3x2 - X+9)​
Andreas93 [3]

Answer:

<h2>{x}^{2}  + 9x - 16</h2>

Step-by-step explanation:

4 {x}^{2}  + 8x - 7 - (3 {x}^{2}  - x + 9)

When there is a (-) in front of an expression in parentheses, change the sign of each term in the expression:

4 {x}^{2}  + 8x - 7 - 3 {x}^{2}  + x - 9

Collect like terms

4 {x}^{2}  - 3 {x}^{2}  + 8x + x - 7 - 9

{x}^{2}  + 9x - 7 - 9

Calculate

{x}^{2}  + 9x - 16

Hope this helps...

Good luck on your assignment...
