Are the following expressions equivalent? Why or why not? <br> 6(2x + 4) and 12x + 24
MrMuchimi

Answer: Yes

Step-by-step explanation:

When using the distributive property, 6(2x + 4) becomes 12x + 24

6 * 2x = 12x and 6 * 4 = 24

12x + 24 = 12x + 24

Therefore, the expressions are equivalent.

How to solve using substitution
DiKsa [7]
X+5 = x^2 - x + 2
0 = x^2 -2x - 3
0 = (x-3)(x+1)

x = -1,3

y = -1 + 5 OR y = 3+5
y = 4 OR y = 8

y = 4,8

So we have two ordered pairs, (-1,4) and (3,8).

Hope that helped!

can you mark my answer as brainliest btw?

A hot-air balloon is moving on a bearing of 2450 at 31mph. A wind is blowing with the bearing of 2600 at 23mph. Find the compone
Alborosie

Answer:

V=(54i) \ mph

Step-by-step explanation:

According to the problem, the hot-air ballon and the wind are movind in the same direction, which means the component form of the velocity of the ballon is the net vector between both velocities.

Basically, the net velocity is

v_{net}=31 + 23 = 54 mph

Because both velocities have the same direction.

Assuming they are moving in a horizontal direction, the component of this velocity is

V=(54i) \ mph
