. Are the expressions 3(m - 2) + 2(m - 2) and 5(m - 2) equivalent expressions?

MA_775_DIABLO [31]

3m - 6 + 2m -4 comblike like terms you get 5m - 10

Then

Factor it you get 5(m -2) so yes the expressions are equivalent

Answer:

the answer is:

16^2 = 7^2 + x^2

256 = 49 + x2

x^2 = 256 - 49

x^2 = 207

I need help with this please!

Answer:

C) x≥4 and x ≤ -4

Step-by-step explanation:

| 8x | ≥ 32

To remove the absolute values, we get two equations, one positive and one negative

8x ≥ 32 and 8x ≤ -32

Divide each side by 8

8x/8 ≥ 32/8 and 8x/8 ≤ -32/8

x ≥ 4 and x ≤ -4

Someone please help me with all !

You can observe that every next term is computed by adding 4 to the previous one.

This implies that the difference between consecutive terms is always 4, and this is an arithmetic sequence.

In order to find the explicit equation, we can explore the pattern:

$a_1 = -1 = -1+4\cdot 0$

$a_2 = 3 = -1+4\cdot 1$

$a_3 = 7 = -1+4\cdot 2$

$a_4 = 11 = -1+4\cdot 3$

So, as you can see, we have

$a_n = -1+4(n-1) = 4n-5$

If 109 is a term of the sequence, there must exist a natural number n such that

$109 = 4n-5 \iff 4n = 114 \iff n = \dfrac{114}{4} = 28.5$

So, 109 is not a term of the sequence.
