Answer

Expressions 4(x+5) and 5(x+4) are Equivalent

Expressions 5(2m+2) and 10m+10 are not equivalent

Step-by-step explanation:

Heres why,

4(x+5) and 5(x+4)

4 times x =4x, so multiply 4x by 5 which should give you 20.

and multiply 5 to x which would be 5x and multiply that to 4 which would be 20, they match up so they are Equivalent.

5(2m+2) and 10m+10

times 5 to 2m to get 10m and times 10m by 2 to get 20.

10m+10 = 1 which they are not equivalent

Answer:

x = 0

Step-by-step explanation:

4 (x+5) = 5 (x+4)

4 (x+5) = 5 (x+4)4x+20 = 5x+20

4 (x+5) = 5 (x+4)4x+20 = 5x+205x - 4x = 20-20

4 (x+5) = 5 (x+4)4x+20 = 5x+205x - 4x = 20-20x = 0

What is the length of AC?

ella [17]

Answer:

2.96

Step-by-step explanation:

The cosine of an angle is the length of the adjacent side divided by the length of the hypotenuse. In this case:

$\cos 65=\dfrac{x}{7}$

$x=7\cdot \cos 65\approx 2.96$

Hope this helps!
