Answer:

B) 7r² - r -1

Step-by-step explanation:

(3r² + 7r + 1) + (4r² - 8r - 2)

1. Remove unnecessary parentheses

3r² + 7r + 1 + 4r² - 8r - 2

2. Combine like terms (ex: r and -2r, n and 4n)

7r² - r -1

Therefore, the correct answer is B.

Hope this helps!

Answer Part A and Part B for the triangle shown

Tom [10]

Answer:

for Part A

Answer is C.

Step-by-step explanation:

$\tan(a) = \frac{opposite}{adjacent } \\$

Here the angle, a is 60°, Opposite is 20 and adjacent is x.

Therefore we have,

$\tan(60 ) = \frac{20}{x}$

Making x the subject gives us

$x = \frac{20}{ \tan(60) }$

Part B

Value of x to the nearest tenth

$x = 11.547 \\ to \: the \: nearest \: tenth \\ x = 12$
