Which expressions are equivalent to 4m + 12? Choose ALL that apply.<br>

riadik2000 [5.3K]

Answer:

Step-by-step explanation:

Option 1:

4(m + 12) = 4m + 48 (not what we want)

Option 2:

6m - 2m + 12 = 4m + 12 (one of the right answers)

Option 3:

4(m + 3) = 4m + 12 (one of the right answers)

Option 4:

3m - m + 12 = 2m + 12 (not what we want)

Therefore the correct answers are Option 2 and Option 3.

Phantasy [73]

Answer:

$14 units$

Step-by-step explanation:

$Solution:-$

$A(5,1)B(7,1)$

$\sqrt{(x_{1}-x_{2} ) ^{2}(y_{2} -y_{1}x^{2} }$

$AB=\sqrt{(7-5)^{2} +(1-1)^{2} }$

$= \sqrt{2^{2} } =2$

$BC=\sqrt{7-7^{2}+(6-1)^{2} }$

$=\sqrt{5^{2} } =5$

$perimeter=2(AB)+2(BC)$

$= 2(2)+2(5)\\$

$= 4+10= 14$

$-----------$

hope it helps...

Find the equation of the line that passes through the points<br> (-4,-2) and (-4,5).

wariber [46]

Sorry I’m not sure if this is much help but the answer is undefined because (y2-y1)/(x2-x1) would equal 7/0 for your slope therefore there is no equation for these points
