No, u cant. Because they are not like terms

Examples :
1 + 2v....cannot add or subtract because they are not like terms
2v + 4v = 6v...u can if they have exactly the same variable
3x^2 + 2x...cant
x^2 + 4x^2...can...= 5x^2
3 + 3 ....can
2 + 5x...cant

now u can multiply and divide one...u just cant add or subtract them

Answer:

B

Step-by-step explanation:

Since the triangle is right use the tangent ratio to find x

tan22° = $\frac{opposite}{adjacent}$ = $\frac{203}{x}$

Multiply both sides by x

x × tan22° = 203 ( divide both sides by tan22° )

x = $\frac{203}{tan22}$ ≈ 502.5 m → B

Let p = points. 0 -6(3) + 4 - 2 = p. Simplify multiplication to get -18 + 4 - 2. -18 + 4 = -14 - 2 = -16.

Ahat [919]

Given:

A person leaves work and travels west for 15 miles.

They then turn left and travel south for 10 miles, to their home.

To find:

Distance between work place and home.

Solution:

The person travels west for 15 miles, then travel south for 10 miles.

It means, it forms a right angle triangle with legs 15 and 10.

To find the distance between work place and home we need to find the hypotenuse of the triangle.

Pythagoras theorem:

$Hypotenuse^2=Base^2+Perpendicualr^2$

$(OB)^2=(15)^2+(10)^2$

$(OB)^2=225+100$

$(OB)^2=325$

Taking square root on both sides.

$OB=\sqrt{325}$

$OB=\approx 18.03$

Therefore, the bird would fly 18.03 miles.
